Cloud Concepts and Architecture

0:06Today it's time to talk about cloud computing roles.

0:10Now, if you've watched wrestling in the past maybe

0:14roughly 20 years or so, you may have heard the saying,

0:18know your role.

0:21Well, even if you haven't watched wrestling,

0:24you may have heard that saying.

0:25And the thing is, in cloud computing, we've got roles.

0:30And the thing is we need to know what those different roles are

0:33because those different roles have

0:35different responsibilities.

0:37So let's jump in and talk about some

0:39of the roles in cloud computing.

0:43So we're starting off with the customer.

0:45Now, the customer is going to be who's using those cloud

0:48services, right?

0:49Yeah, we know that.

0:50But here's the thing.

0:51When it comes to cloud computing,

0:53the customer is going to own the data, right?

0:57It's the customer who's going to upload the data into the cloud

1:01environment.

1:02And it's the customer who's going

1:04to use the platform as a service to go out and build

1:08different applications.

1:10So the customer's using data, right?

1:13They're uploading their data into the cloud.

1:14They're using and building applications in the cloud.

1:18They're using those services.

1:20So that is the role of the customer.

1:23But what other roles are there?

1:25Well, we've got a cloud service auditor.

1:27That's a role.

1:28And these are folks that are out there verifying

1:30that those Cloud Service Providers, those CSPs,

1:34are doing what they're supposed to do.

1:36They're meeting their Service Level Agreements, or SLAs.

1:40So these auditors are actually out there

1:42to help the customer, right?

1:43They're out there to help make sure

1:45that those CSPs are doing things like they're supposed to

1:49and like they say they're doing and again,

1:51meeting those service level agreements.

1:54And next up is the cloud service broker.

1:58Now, this is a person, or actually an organization,

2:02that kind of maintains relationships

2:04with multiple cloud service providers.

2:07So they've got a bunch of CSPs out there

2:10that they work with, this cloud service broker over here.

2:14And what they do is they kind of act

2:15as a consultant to the customers.

2:19Because when a customer is deciding that they

2:22want to go into the cloud--

2:24they want to start using cloud services-- they

2:25may go to a cloud service broker as a consultant

2:29to help them identify which cloud solutions meet our needs

2:33or which cloud service providers best fit our organization's

2:38needs and requirements.

2:40Because this cloud service broker over here

2:43is going to be very familiar with all these different CSPs

2:47they have relationships with.

2:48And they're going to know about their services

2:50and how they do business and all those things.

2:52So as a customer, we can rely on a cloud service broker

2:56to help us identify what cloud services and cloud service

2:59providers might best fit the needs of our organization.

3:03And yes, it's true these cloud service brokers do sometimes

3:07resell cloud services.

3:10And that's just kind of part of their business model.

3:13Next up?

3:13Well, we can't leave out the cloud service providers, right?

3:16Those are the folks out there in the cloud

3:18providing the services.

3:19They provide us with the CPU in the cloud, the memory,

3:23the storage in the cloud.

3:25They provide us with the platforms for our platform

3:29as a service, right?

3:30They provide us software.

3:32That's part of software as a service.

3:35And then of course, these up here,

3:37if we put that over there, these are

3:38part of your infrastructure as a service.

3:41And then they provide us with billing as well, right?

3:44They're going to bill us.

3:45But they also track our usage.

3:47And that really is something very important because again,

3:50the cloud services, it's kind of a pay-as-you-go method.

3:56And it is a metered service.

3:58So you only pay for what you use.

4:01That's your usage.

4:02That's the meter.

4:03And you kind of pay as you go.

4:04And your cloud service provider is providing these services

4:07to you as the cloud customer.

4:10And we got one more to talk about,

4:12and that is a cloud service partner.

4:14And these are roles that support and work with the CSPs.

4:19And these are any roles, such as a cloud service

4:22broker that we talked about, or it could be a cloud service

4:26auditor.

4:27So those brokers and auditors are kind of

4:31in a supporting role.

4:33And they help support the CSPs.

4:36And they are a cloud service partner.

4:39And there we go, cloud service partners.

4:41And that is the list of the roles

4:44that we need to know about in the cloud.

4:45We had our cloud customer.

4:48Of course, that was us, using cloud services.

4:51Or I guess if you work at a cloud service provider,

4:54then that wouldn't be you necessarily.

4:55But it's going to be our cloud service auditors, of course,

4:59as well.

5:00And then we had the brokers, who brokered services and helped

5:04us identify as a customer which services best met our needs,

5:08maybe which cloud service providers best met our needs.

5:11And of course, we got the providers

5:13who provide all those great cloud services

5:16and then lastly, our partner.

5:18So those are the different roles in cloud services.

5:21Hope this has been informative for you,

5:22and I'd like to thank you for viewing.

0:06I've got a question for you.

0:08What makes you awesome?

0:10Is it your sense of humor, is it your leadership

0:13abilities, or maybe it's your depth

0:16of knowledge in something.

0:17But these are all characteristics

0:19that you have that make you awesome.

0:21Well, cloud services have characteristics as well.

0:25And guess what?

0:26They make them awesome as well.

0:27So let's jump in and talk about some

0:29of these cloud characteristics.

0:32So here we're talking about cloud computing characteristics

0:35and, of course, all those things that make it awesome.

0:37Well, let's start with number one.

0:39On-demand self-service.

0:41Now this is pretty darn cool.

0:43Think about before cloud.

0:45If you're not using cloud, then think about today.

0:48You want to deploy a new server.

0:49Well, what are you going to do?

0:51Well, I need to go and I need to get approval

0:54to purchase a new server, I need to order that server,

0:58and then I need to--

0:59I'm can put dash, dash, dash--

1:01wait for that server to come in.

1:03Then, once it does come in, then we're going to go

1:05and we're going to unbox it, and we're going to rack it.

1:10We're going to cable it up, then we're going to fire it up.

1:12We're going to install our OS.

1:15And then we're going to do our patching.

1:17And then we're going to do whatever

1:18else it is that we need to do to make that server what

1:21we want it to be.

1:22That is a lot of work.

1:24And guess what?

1:25It takes a lot of time.

1:27Wouldn't it be great if we could just do away with most of this?

1:31Well, we can and there's the on-demand self-service.

1:34We can log into our cloud console

1:37and we can click some radio buttons or widgets in there.

1:41And we define how much memory, how much CPU we need,

1:44how much storage we need.

1:45We go through this.

1:46And within just a couple of minutes,

1:47we have a server up and running spinning

1:51in our cloud environment.

1:53Now you take-- let's say it was five minutes.

1:55Five minutes versus maybe five weeks if you're lucky.

2:00So that's a big difference and it's on-demand.

2:03If you want to make changes, boom, jump in there

2:05and make changes.

2:05And that is pretty darn awesome when

2:08it comes to cloud services-- our on-demand self-service.

2:11We also have global access, which

2:14really is the whole idea of using your cloud management

2:18console.

2:19You can log into that from anywhere in the world,

2:21doesn't matter where you are.

2:22You're on vacation and you've got an emergency,

2:24you've got to jump in and work on it,

2:25or maybe you just want to work remotely.

2:27A lot of us are doing that these days.

2:29And you can manage your environment from anywhere.

2:32You have global access, super, darn handy.

2:35Think about on-premise.

2:37When it's on-premise, how do you manage it?

2:38Well, generally, these days, we manage it anyway.

2:41We VPN into our environment and then we manage it from there.

2:45But if you didn't have VPN, how are you going to manage it?

2:48It can be tricky.

2:49Well, we don't have to worry about that with cloud access.

2:51It's super, darn easy.

2:53Our cloud global access.

2:56Next up, resource pooling.

2:58Now when it comes to resource pooling,

3:00well, we think about this, maybe we've

3:02been doing this ourselves.

3:03We have all these different resources

3:04and we use them as we see fit.

3:07Well, in cloud environments when the cloud vendors purchase

3:10and set up their environment, they've

3:12got all this CPU and memory and storage and network

3:18that they've created right.

3:20And they've got these giant pools of resources

3:23for all these different things.

3:25And what that does is it allows them to use this pool very

3:30efficiently.

3:31They can fit a lot of customers in these pools of resources.

3:35And the idea is they can use large amounts of resources

3:39like maybe they operate at 80% capacity.

3:42Well, if you think about it, when we have a server on-site,

3:46on-premise, and maybe this is an active directory or a file

3:50server something, well, we realize if you check your CPU

3:53and your resource utilization, in a good day,

3:56we're running at 20% utilization probably.

3:59But on average, it might be 15% or 18%.

4:03We're not using much, so that's a lot of wasted resources

4:07and wasted money too because we paid for this server,

4:11but we're only using 20% of its capacity.

4:14Well, the thing is, with the cloud providers,

4:17they're able to create these pools

4:18and efficiently use a large majority of it.

4:22So what that does is it makes it more efficient.

4:26It allows them to get more bang for their buck.

4:29And then they can pass that savings

4:31onto the cloud customers.

4:34And why would they want to do that?

4:36Because if they can make cloud more attractive price-wise,

4:41then on--premise, well, why wouldn't you go to the cloud?

4:43It just makes more sense.

4:45So that is our resource pooling.

4:47Next up, resource elasticity.

4:50Now this is awesome.

4:52I love this about cloud.

4:53And here's the thing.

4:55When we have our on-premise servers,

4:58we have a set amount of resources.

5:00We deploy our servers over here and we have a set

5:04amount of CPU, memory storage--

5:09put storage-- and networking.

5:11We only have what we have.

5:13It's not like we can instantly get more.

5:15We can always go down, but we can't go up, necessarily.

5:18Well, in the cloud, ha-ha, we can go up

5:21and we can go back down.

5:22So think about this.

5:23If you're running a web server out here--

5:26there we go-- and it hosts an application that people use,

5:30but certain times of the day, it gets absolutely hammered

5:34and it gets slow.

5:36Wouldn't it be great if we could add more resources

5:40to it or maybe a second instance of that server,

5:44but only during certain periods of the day?

5:46And then during the off periods when we're not real busy,

5:50well, we could actually just get rid

5:53of that extra server or resources.

5:56Well, guess what?

5:57We can do that in the cloud and it is resource elasticity.

6:01So during peak periods of the day up here,

6:04we can increase our resources.

6:07And then during our low demand periods,

6:09well, we decrease our resources.

6:11And this could be automated.

6:13But why do that?

6:15Well, here's why.

6:16Let's jump over here and see why resource elasticity is

6:19so awesome.

6:20Because cloud is a measured service.

6:23You pay for what you use.

6:26So what that means is if you can only

6:28pay for a lot of resources during peak periods

6:31and a little bit of resources during your downtimes, well,

6:35wouldn't that be great?

6:36It's very efficient dollar-wise.

6:39We're not wasting money on resources we're not using.

6:42And that's why resource elasticity really

6:44can save us some money and help us meet

6:48the demands of our customers.

6:50And that's pretty darn awesome.

6:51Now, again, yes, measured service.

6:54We're only paying for what we use.

6:56So think about this.

6:57On-premise, when we buy those servers and deploy them,

7:01maybe we're using 30% of the resources on those servers.

7:05Well, we're still paying for 100% of those servers

7:09that we bought and staged and racked and got ready to roll

7:13and are managing.

7:14But we're only using 30% of their ability.

7:17Well, that's not cool.

7:19Well, that's the thing with measured service,

7:21we only pay for what we use.

7:24So we would only be paying for our 30% that we're using.

7:28And that is super awesome because now we're

7:30not wasting resources.

7:32And, yes, money is a resource.

7:35So there you go.

7:36Those are some cloud computing characteristics.

7:38We had our on-demand self-service, global access,

7:42resource pooling, resource elasticity,

7:45and measured service.

7:46And, yes, they do provide us benefits.

7:49They help us to only pay for what we use and adjust

7:53what we're using to meet demand and access

7:56and manage it from anywhere, and make changes on a whim.

7:59So those are some characteristics that

8:01make cloud computing awesome.

8:03I hope this has been informative for you,

8:05and I'd like to thank you for viewing.

0:00[MUSIC PLAYING]

0:06When you go shopping for a vehicle.

0:09Well, you've got different models to choose from.

0:11You have got sedans, and coupes, and trucks, and SUVs.

0:16All these different types of models to choose from.

0:18And the same is true for cloud.

0:20There are different models of the cloud.

0:23So let's jump in, and talk about some

0:25of these different models, and some reasons

0:28that you would choose one over another.

0:31So our cloud deployment models that's

0:33what we're talking about here.

0:35We've got private, public, community, and hybrid.

0:40Those are four different cloud deployment models.

0:43So let's take a closer look at each of them.

0:45Starting off with private.

0:47So the private cloud is private. .

0:50It's used by a single organization.

0:53So this means that only one client is

0:56housed within this cloud here.

0:59And this cloud could be managed by the client themselves,

1:02or it could be managed by a cloud service provider.

1:06So it could go either way.

1:08The client managing it, or the cloud service provider.

1:11Now, what are some benefits of a private cloud?

1:15Well, some benefits would be increased control

1:20over the data, and its underlying systems.

1:23Definitely retaining of ownership of the data,

1:27because if you don't have any other clients, where you could

1:29have some cross-contamination of data,

1:31or you're going to have a better chance

1:33of retaining your ownership.

1:35You also have the ability to add additional governance

1:39of controls.

1:41And that's because in another type of cloud,

1:43the public cloud, where you have lots

1:45of different customers in it, you

1:47might not be able to make changes or have

1:48the CSP make changes for you, because it

1:51would affect other clients.

1:52But here we could actually have additional controls

1:56over the governance, and maybe add additional security

1:59controls.

2:00And we also have additional assurance of data location.

2:06Because if we have a single cloud,

2:09where we are the single client in that cloud,

2:11we know where it resides.

2:13And we're going to talk about this as the course goes on,

2:16the importance of knowing your data's location.

2:19It comes in very handy, especially

2:21for legal and compliance requirements.

2:23And then lastly, probably the biggest one is privacy.

2:28And that's because if you are the only customer

2:32in this cloud, well guess what?

2:34It's all yours.

2:35You have all the privacy.

2:37So that is a private cloud.

2:39Now, guess what?

2:40[LAUGHS] Yes of course, private clouds cost more.

2:43Because you are shouldering all those expenses of that

2:48cloud yourself.

2:49Or your organization is at least.

2:51So keep that in mind.

2:53Now, what about the public cloud?

2:56The public cloud is a lot different than a private cloud.

2:59Anybody can sign up and use it.

3:01So that is anybody, including bad guys.

3:07And yes, it is possible.

3:09And they do, they sign up and they

3:10use cloud services to launch attacks, and do things.

3:13And yes CSPs or cloud service providers

3:16are out there looking for them, so that they

3:18can knock them offline and revoke their cloud services,

3:21but they are out there so anybody can use it.

3:24And this is your standard cloud service that you think about.

3:27When you think about AWS, and Google Cloud, and Azure,

3:32generally you're thinking about a public cloud.

3:34When you go sign up for an account,

3:36and you spin up resources in the cloud,

3:38well, that's a public cloud.

3:40And your data is isolated between customers,

3:45so that other customers can't access your data,

3:48and you do have the isolation.

3:50But you are sharing the underlying resources.

3:53And that's why it's a public cloud.

3:54Now, some of the benefits of the public cloud are ease of use.

4:02Because it is very easy to use.

4:04You sign up for an account, you log in to your cloud dashboard,

4:07and you can start spinning up instances, or using

4:10the platform to build applications,

4:12or whatever it might be.

4:14And user data is isolated.

4:18And that's very important, because when

4:19you have lots of people using the same service of course,

4:23we want to make sure that our data is

4:25isolated from each other.

4:27So that client A can't access client C's data

4:30over here, that would be a bad thing.

4:32And that is a benefit of the public cloud.

4:34Also with the public cloud, well guess what?

4:37In comparison to a private cloud it's a reduced cost.

4:40Because you're not shouldering the expenses

4:42for the entire cloud setup on your own.

4:45This is a shared endeavor, with all those other users

4:49out there.

4:50Next up is our community cloud, and this

4:53is a pretty interesting one.

4:54And it's kind of a cross between a private cloud,

4:59and a public cloud.

5:00And here's why I say that.

5:02You have multiple users like a public cloud.

5:05However, you all share the same need for a specific service,

5:12or something.

5:13So you're all kind of working towards the same goal.

5:16You're different organizations yes,

5:17but you all have the same goals when it comes to the cloud.

5:21So here's the community cloud

5:23It's used by a group of users that we see down here.

5:26And they all share the same need,

5:28they share the same cloud service, and cost.

5:31So the thing is there is a shared need here,

5:34and then you all shoulder that costs together.

5:37So it helps to drive the cost down, which is a good thing.

5:41Now, the example I'd like to use with this,

5:43is because I've set this up for this exact scenario,

5:46is a group of doctors.

5:48So you've got these doctors offices over here,

5:51let's say we've got three of them.

5:53And they all share, or they want to start

5:56using the same electronic medical record system.

5:59And the thing is, these EMRs, these electronic medical

6:03systems are pretty darn expensive.

6:05And if you spin up an individual instance

6:09for each of these offices, well then all of them

6:12are paying a lot of money.

6:14Wouldn't it be great if we could spin up one instance somewhere?

6:17I don't know, maybe in the cloud.

6:19And they could all share that instance.

6:23Well, guess what?

6:24You can.

6:24And that is a perfect example of a community cloud.

6:28These folks all want to share the same resource,

6:31and it helps to drive down the cost of that resource.

6:36So some of the things that you get,

6:38some of the benefits of community cloud,

6:41are high availability, and resiliency, that's HA,

6:45and resiliency that you get with cloud services.

6:49Basically redundancy, and things that the provider has.

6:53They have redundant hardware, and redundant networking.

6:56And all the stuff that if I was to set this up

6:59in a doctor's office, they're not

7:00going to have all that stuff.

7:02But if we spin that up in the cloud.

7:04Yes, they are going to have that.

7:07So that's where we come up with a benefit of high availability,

7:10and resiliency.

7:11We also have a benefit of added security.

7:15Because many of the cloud service providers

7:17are compliant with lots of different things

7:19like HIPAA, and PCI, and SOC, and NIST.

7:22All things that we're going to talk about in time.

7:25There is a reduced cost of course,

7:28because they're sharing the cost of this.

7:30Instead of spending it up on their own individually,

7:33they get to share the cost, which is super cool.

7:36And then lastly, flexibility.

7:38And I say flexibility because if we buy a server

7:41and spin it up on premise, in one of the doctor's offices,

7:44and we need more memory, or more CPU, or more storage,

7:48well we have limitations.

7:51A server that we purchase can only have so many CPUs in it.

7:55It can only hold so much memory.

7:58It can only hold so much storage.

8:01You see where we're limited here.

8:04But in the cloud, I can just add, and I can add,

8:07and I can add, and I can add, and yes there

8:09are limits of course, there's limits with anything.

8:12But they're pretty out there.

8:14You can add a ton of resources.

8:17And you can do it pretty darn quick,

8:18with just a couple of clicks, and you've

8:20got these added resources.

8:22Completely different than on premise.

8:24So this is a community cloud.

8:27And we've got one more, and that is a hybrid cloud.

8:30And really it's just a combination

8:32of any of the other.

8:33So if you take a public, or a private,

8:37or a community cloud, and you combine them.

8:41Well then you have hybrid right.

8:43Pretty darn straightforward.

8:46Now some of the benefits of hybrids

8:49include, hardware it's our HW reuse.

8:53And that might sound crazy to you.

8:54You think in the cloud it's often some far off data center.

8:58How can I use my hardware in that data center?

9:01Well, here's the thing.

9:02When you have cloud, you could have

9:04a private cloud let's say on premise if you wanted to.

9:08Because a cloud is just a group of services,

9:11and you might have an on prem, put here on prem.

9:17Little cloud that you set up.

9:19So it's your cloud, and you're managing it.

9:22It is a private cloud let's say.

9:25And really what I'm referring to, this is your environment,

9:28you're managing it and it is private.

9:31But if you take that, and you connect it to the public cloud

9:36where you have an account, and you spin up some resources

9:38out there.

9:39And you set up a VPN between these two,

9:42guess what you've done?

9:43You've created a hybrid cloud.

9:45You have your private on premise type of cloud,

9:48and you have just combine that with your public cloud account.

9:52And there you go.

9:53So that it is hardware rees where

9:55you can use some of your local hardware, in your hybrid cloud.

10:00Now, another great piece of a hybrid cloud,

10:04is using the cloud for disaster recovery purposes.

10:09Let's go back to your private on prem cloud.

10:12Well, wouldn't it be great if you replicated

10:14that data up to a public cloud account,

10:19and you use it for disaster recovery?

10:22Well, you could do that.

10:23And that is a hybrid, because you're

10:25combining your private on prem cloud, with a public cloud

10:29account there you go.

10:31One of the other things you might want to do

10:33is look at reduce cost by combining your

10:37on prem private cloud, with a public cloud account again.

10:42But this time what you're doing, is

10:43you're taking the things that you

10:46can put in the public cloud that are very little resources.

10:49Maybe something new you're spinning up

10:50instead of going and spending a bunch of money on new servers,

10:54well you just spend it up in the cloud, and your connected to.

10:57There you go.

10:57That's another example of a benefit.

11:00Now, here's the thing.

11:01I don't want you to think that a private cloud has

11:03to be on premise, because by no means does it have to be.

11:08You can have a private cloud in a data center

11:11in your same town, that somebody owns.

11:14And they set up some hardware for you,

11:17kind of like a co-location, and that's your private cloud

11:20there.

11:21Or you could have a private cloud, on premise,

11:23or you could go to one of the big dogs.

11:25One of the AWS, or a Azure, or GCP, and you

11:28could talk to them about private cloud.

11:30Where they're going to set up your own hardware,

11:31your own environment.

11:33But it's going to be very expensive I'll tell you that.

11:36But there you go.

11:37You can have private cloud anywhere.

11:38I just don't want you to think that you

11:40have to have it on Premise, because you definitely do not.

11:43So those are some different cloud deployment models.

11:45But I also said we're going to talk about choosing one,

11:47and what kind of requirements drives your choice.

11:51So choosing a model.

11:54Well, when you're choosing a cloud deployment model,

11:56it needs to be based on a couple of different things.

11:58Number one is your business strategy.

12:01Whatever your business strategy is,

12:03you need to take that into consideration.

12:05Are you trying to go global?

12:08Are you staying local?

12:09Because if you're going global, then then the cloud

12:11would be the way to go.

12:12Because you're going to want to put your resources

12:15in multiple locations around the globe possibly.

12:18Well, and something else to consider

12:20is your compliance needs, or any type of regulatory needs

12:25that you might have, you need to know those.

12:28So when you go looking for a cloud service provider,

12:31you can make sure that CSP, that Cloud Service Provider is going

12:35to help you meet those needs.

12:37And of course cost.

12:39[LAUGHS] We can't forget cost.

12:41Cost always comes into play.

12:43What about our risk appetite?

12:45Let's talk about that for a minute.

12:47Your risk appetite is how much risk your organization is

12:50willing to accept.

12:52So when you're talking about risk appetite,

12:54if you have very sensitive information,

12:58well putting that in a public cloud

13:00does have some risks associated with it.

13:02And it might be too much risk.

13:04You may decide to go with a private cloud because

13:06of your sensitive information.

13:09And then lastly, any legal obligations you may have.

13:13And this could be contractual, or it could be due

13:15to regulatory requirements that you are not able to put certain

13:19data in certain places, or certain data cannot leave

13:23the country.

13:24Those are all things to consider,

13:26and that goes back to understanding

13:28where your data is located.

13:30We talked about that briefly, we're

13:32going to talk about it more later on don't worry.

13:34But these are some of the things that

13:36will help us decide, which of these cloud

13:39deployment models is right for us.

13:42I hope this has been informative for you,

13:43I'd like to thank you for viewing.

0:06When it comes to cloud, there are three main types

0:09of services, and we're going to talk about those three types

0:12over the next three videos.

0:14In this video, we're going to talk about infrastructure

0:16as a service.

0:17The key word here is infrastructure,

0:19and it is the most similar of the three different types

0:23to your standard on-premise servers and networking.

0:27So let's jump in and talk about infrastructure as a service.

0:31So here we are, IaaS, infrastructure service,

0:34what the heck is it?

0:36Well, as I said, this is the most similar

0:38of the cloud Services to your on premise network and server

0:42architecture.

0:43And this is where the customer can log in to their cloud

0:47service portal and they can go ahead

0:49and they can provision their own processing, storage,

0:53and networking capabilities.

0:55So basically here you're building a network

0:57infrastructure in the cloud.

0:59So what you're doing is you're building out your network.

1:03So you're setting it subnets in the cloud,

1:07you're going to be setting up your routing in the cloud,

1:11you're going to set up your security groups,

1:14and these are your access control lists for your security

1:17for network-based accessing certain subnets and port can

1:23and cannot communicate to different subnets.

1:26You're going to be spinning up servers,

1:29and the servers of course include your CPU, your memory,

1:34your storage, and your operating system.

1:38You're also going to be dealing with public IPs,

1:42and, of course, private IPs, and then, of course, at that point

1:46you've got NAT that's involved.

1:49So these are all things that we deal with on premise,

1:52except here we're doing it in the cloud.

1:54Now, some of the benefits of using the cloud IaaS over an on

2:01premise is your scalability.

2:05Because you can scale very fast.

2:07You don't have to go buy new servers and rack them,

2:10we've talked about that, you can just

2:11go add more storage or CPU or memory or additional servers as

2:16needed.

2:16And that also leads to on-demand service,

2:21because we can do it on demand, we just log in and do it.

2:25Super cool, and it is a self-service.

2:28So the customer themselves can log in.

2:31You don't have to put in or request to a cloud service

2:33provider to go and make this change for you.

2:36You can just log in and do it.

2:37Really cool.

2:38We have resiliency and reliability.

2:43And this is different from on premise in most cases, not all.

2:47Because your cloud service provider,

2:49they're setting up in this giant data center.

2:52In that data center, they generally

2:54have feeds from two different power grids, a lot of times.

2:59They'll have their own water resource for cooling on site.

3:02They'll have their own power substations on site.

3:05You see where I'm going with this, right?

3:07They got giant battery banks on site.

3:10They spend billions of dollars on these data centers

3:13with all this redundancy.

3:15Well, you can't do that in most cases

3:18for your on-premise setup.

3:20We're lucky if we have a decent-sized battery backup

3:25or up system to support our infrastructure,

3:29and that is one of the great benefits of cloud

3:32is all of that added resiliency and redundancy

3:35that's built into it.

3:37And then we have a reduced cost.

3:40And that's because when you take a look at all that you're

3:43paying for on premise and you compare it to the cloud,

3:46in most cases, I'm not going to say all cases, in most cases,

3:50you will achieve a reduced cost.

3:53And this is a reduced total cost of ownership, or TCO.

3:59Now, think about this.

4:01When you have an on-premise setup,

4:03you're paying for those servers, you're

4:05paying for all that labor to set them up and then manage them.

4:11If you're using virtualization, you

4:13have hypervisors that are running

4:15on them that have to be managed and patched

4:17as well as the guests running on them,

4:19you've got your network you have to manage,

4:22you've got for all those things, you

4:25have cooling for all those things, and the list grows.

4:29It does, I'm telling you, it grows and grows and grows.

4:31And when you get down to the nitty gritty of all

4:34these things and add them up, guess what?

4:36You're probably going to save money in the cloud.

4:39And think about this too.

4:40For all that hardware that we purchase on premise,

4:43we have to buy annual maintenance contracts

4:46form if we want to continue to receive support for them

4:50and get the updates, which, believe me, I always

4:53vote for that because that way you

4:55have support for your devices.

4:56You're not out in the cold left alone,

4:58and you've got annual licensing costs

5:00that come into play as well.

5:03And these things add up.

5:05So that's where we get our reduced total cost

5:08of ownership.

5:09So that's infrastructure as a service.

5:11So if you're looking to spin up virtual servers in the cloud

5:14and run a network, just like you do on premise,

5:17then IaaS is for you, and you get all these benefits

5:21that come along with it.

5:22I hope this has been informative for you.

5:24I'd like to thank you for viewing.

0:00[MUSIC PLAYING]

0:06Next up in our cloud services is platform as a service or PaaS.

0:12Now, this is for all you developers out there.

0:15And what this is, is a platform in the cloud

0:18that you can use to build out your applications

0:21as you see fit.

0:22And it's really darn neat.

0:24I like to think of this like LEGOs

0:25in the cloud for developers, because you've

0:27got a platform with all these tools and abilities,

0:31and you get to create some pretty cool things.

0:34So let's jump in and further discuss platform as a service.

0:38So here is our PaaS or platform as a service.

0:41And I said, it's used to develop applications and such.

0:45And it's really darn cool.

0:48And again, I like to think of this like LEGOs

0:51in the cloud for developers, because you can build anything

0:54your imagination musters up.

0:56And there's lots of cool things they

0:58include in these, lots of new things like quantum computing

1:02and different things like that, where you can actually

1:05tie into these different features

1:07and use them in your application.

1:09Now, let's talk about this.

1:11So when we're using platform as a service,

1:14basically, we're given a bunch of different tools and features

1:18that we can use to develop applications

1:20which is super awesome.

1:21And this could run in a private, public, or hybrid cloud.

1:25It gives you lots of flexibility.

1:28And it supports multiple programming languages.

1:32And, of course, it has lots of scalability like everything

1:35else in the cloud.

1:37And much of the scalability can be automated

1:41so that it's not something we have to manually do.

1:44So you can tie into this as a developer, when

1:48you're developing on a platform in the cloud.

1:51Now some benefits that we have with platform

1:55as a service, other than these up here,

1:58are global collaboration, meaning this platform

2:02and cloud is available anywhere in the world.

2:04So if you have a bunch of different offices

2:06around the globe, well, they can all log in and collaborate

2:11together on what's being built. We also

2:14achieve some cost reduction in comparison

2:19to native development, because the idea here

2:22is that we can actually use a single vendor

2:26to supply all of our needs.

2:27We don't have to go across vendor.

2:30So that can allow us to achieve some cost reduction.

2:34We also have global access for all the customers using

2:38these applications we build because they're available

2:42globally.

2:42But you might say, well, so is what I build on Premise.

2:45I built an application, I opened it up,

2:47and anybody can access it from anywhere in the world.

2:49Yes, but if you are running this from one single location

2:55and you have somebody across the globe trying to access it,

2:59well, they're going to see some latency, some slowness,

3:02different things like that.

3:03Well, with the cloud you can actually

3:05deploy this across multiple data centers

3:08around the world to better service your customers.

3:11So that is platform as a service and some of its benefits.

3:15I hope this has been informative for you.

3:17I'd like to thank you for viewing.

0:06All right.

0:07The last type of cloud service we're going to talk about

0:09is software as a service.

0:11This has been around for a long time.

0:14We've been using software as a service

0:16and didn't even know it was a cloud service per se.

0:20And we're going to talk about what it is.

0:22And then you'll see why you may have

0:24been using this for many years and didn't even realize

0:27you were already using cloud services.

0:31Software as a service, it's very simple.

0:35It's just software that is running in the cloud

0:37that you use.

0:39Now, you think, well, my company doesn't have a cloud account,

0:42really, and they don't create applications in the cloud.

0:46So we don't use software as a service.

0:48Ah, but wait, you probably do.

0:50Have you ever used web mail?

0:54And maybe you did that through a vendor,

0:56like you use Office 365 email.

0:59Well, guess what?

1:00That is software as a service.

1:03Do you maybe have some type of HR or accounting application

1:09that you log into via a web page?

1:12So I know there's different examples of them

1:15out there, like Bamboo HR.

1:17These are all different types of software as a service.

1:23So when you go and you log in to a website of a company

1:25and use an application, that software as a service.

1:29So it's really simple.

1:31But there are some great benefits,

1:34like on-demand access, right?

1:36We can access it from anywhere.

1:37So we have anywhere access, or global access,

1:43and of course, on-demand access because we can log into it

1:47whenever we want to.

1:48It also allows us to achieve some reduced costs.

1:52Because if we use, let's say, an HR platform,

1:58if we want to use that on premise,

2:00we'll have to pay for licensing for it.

2:03I have to buy a hardware for it, some hardware,

2:07like a server, with storage and processing all that stuff,

2:10plus licensing for the software, my HR software,

2:13licensing for the operating system, support contracts.

2:16The list goes on and on and on, plus management fees, blah,

2:19blah.

2:19Well, you see, when we talked about our Total Cost

2:22of Ownership, or TCO, we see how much it actually

2:25cost to run something on site.

2:26So this is where we can achieve some reduced costs.

2:30We have no deployment costs, right?

2:32Because generally it's being set up by the vendor.

2:35And we send them some information to populate in it.

2:38We're not buying servers.

2:39We're not racking servers.

2:40We're not doing any of that.

2:41We're not spending a lot of money to get up and running.

2:45Now, let's talk about something real quick.

2:46I want to talk about capital expenditure, or CapEx,

2:50versus operational expenditure, or OpEx.

2:55Now, this might be something new to you.

2:57These are financial terms.

2:58But it plays into, really, cloud services in general

3:03because CapEx is when you spend the money up front to purchase

3:08all of what you need.

3:10So let's say we're going to roll out a new HR platform.

3:14Let's just go with that.

3:15And we'll say, it's going to cost us $15,000 in hardware.

3:21It's going to cost us $5,000 in software.

3:25And then to get this set up and racked and everything done,

3:29it's going to cost us an additional $2,000.

3:32And we'll say install.

3:34There we go.

3:35So it's going to cost us $17,000 to get this new HR platform up

3:40and running.

3:41That would be capital expenditure.

3:43We're going to spend $17,000 to get this up

3:46and running versus operational expenditure.

3:50Basically, at this point, it would

3:52be whatever the setup fee is for this new platform.

3:57And it might be $0, or it might be $2,000.

4:02I don't know.

4:03But the idea here is, then, once we're set up,

4:06we're going to pay a monthly fee to use this product, right?

4:12And that is an operational expense.

4:15It's part of operations.

4:16They're paying x dollars a month to use this forever

4:20until we're done with it.

4:21Whereas a CapEx, we're spending a whole lot of money

4:24up front to set this up so that we can use it on premise.

4:29And then we will have annual maintenance contracts

4:32and software contracts and licensing contracts

4:35that we have to pay every year, every three or five years,

4:39whatever it is.

4:40But the idea is that CapEx is a large upfront

4:43expenditure of capital, meaning money, to get up and running.

4:48Whereas in OpEx, this is something

4:50we're going to pay for every month.

4:53So you'll see the spending is different.

4:55And when we go with a software as a service,

4:58well, that's an operational expenditure, or an OpEx.

5:02Now that we got that explained, let's go ahead

5:04and talk about some SaaS benefits.

5:07Well, it's going to be, number one, reduced cost.

5:11And this is going to be in most cases

5:14because sometimes vendors out there

5:17will price themselves just ridiculous, right?

5:19We know that.

5:20But in most cases, you're going to see reduced cost

5:24because we don't have to perform a CapEx, right?

5:27We don't have to spin that bunch of money up front to get up

5:29and running.

5:30And we don't have to pay for labor to get this thing up

5:33and running.

5:34We don't have to pay for operating system

5:36license, hardware support contracts, all that stuff.

5:38We don't have to worry about that because we just pay

5:40our software-as-a-service vendor,

5:42our operational expense, our monthly fee.

5:45How about ease of licensing?

5:49Because anybody out there who's dealt with licensing

5:52knows what a pain in the rear it can be.

5:54We don't have to deal with it because the

5:56software-as-a-service vendor takes care of the licensing.

5:59We just pay them the fee, and that's handled,

6:01so ease of licensing.

6:03Less administration-- yes, the application itself

6:07we might have to do some in administration,

6:09like creating new users and things.

6:11But what about all the underlying

6:13hardware that we would have to manage if it was on premise?

6:16We'd have to manage the operating system it runs on,

6:19manage the server, manage the backups,

6:22manage the actual application installed on the server

6:27and do the patching for that.

6:29There's a lot of administration that just doesn't have

6:31to happen anymore, not by us.

6:33The software-as-a-service vendor takes care of that for us.

6:37And then, of course, global access--

6:41and yes, if you set this up on premise

6:44and you set up maybe a remote access VPN,

6:47then users could securely access it.

6:49But that's, again, something else

6:50you have to administer or manage.

6:53Well, that goes away.

6:54You can access this software as a service from anywhere.

6:57Just log in to the website and access it.

6:59So that is pretty darn cool.

7:02So those are some benefits of software as a service.

7:05I hope this has been informative for you.

7:06I'd like to thank you for viewing.

0:06So we just finished talking about the three primary types

0:10of cloud services.

0:11That was infrastructure as a service, platform as a service,

0:15and software as a service.

0:16And we talked about the benefits and all the cool things

0:18about them.

0:19But did you stop to think about, well,

0:22if I use this one, like infrastructure as a service,

0:26what am I responsible for?

0:28Does the cloud service provider do everything,

0:31or do I do everything, or is it shared?

0:33Well, the answer is it is shared,

0:35and that's across all of them.

0:37There's something known as shared responsibility.

0:40And that is a super important term

0:42to know and understand when it comes to the cloud

0:44because that means that cloud service

0:47provider is responsible for some things, but not everything.

0:50And the customer is responsible for some things, but not

0:53everything.

0:54So who's responsible for what?

0:57How do I know?

0:57Well, we're going to talk about that right now.

1:00So here is a sample outline of cloud service provider

1:05versus customer responsibilities.

1:08Now, when it comes down to the actual responsibilities,

1:12these need to be outlined somewhere in a contract.

1:16And generally your cloud service provider

1:18will have a document that outlines a bunch

1:22of this information for you.

1:23What we're looking at here is an example.

1:25This is not, like, a set-in-stone kind of thing.

1:28It could change.

1:29So when we talk about physical security-- that's the first one

1:32we're looking at.

1:33Think about this.

1:34This is in the cloud, right?

1:35Do you, the customer, have access

1:38to the physical infrastructure, the building,

1:42the servers in the cloud?

1:43The answer to that is an astounding no.

1:46So of course, the vendor is responsible for all

1:51of the physical security, no matter

1:53if you're using infrastructure as a service,

1:55platform as a service, or software as a service.

2:00What about the underlying hardware patching?

2:02Here we're talking about like hypervisors

2:04and the platforms being used and the software that they

2:07are providing us with, with software as a service.

2:09Well, we don't have access to that as a customer.

2:11So of course, the vendor is going

2:13to be responsible for all of that.

2:16What about virtualization management, so the hypervisor

2:20and the underlying virtual technologies

2:21that are being used?

2:22Well, as a customer, again, we don't have access to that.

2:25So it's going to be the vendor.

2:27What about operating system and application patching?

2:31Here we start to see the shared responsibility.

2:34When it's an infrastructure to service, if I, the customer,

2:38am building a Microsoft Windows Server that I'm

2:41running in the cloud, I'm responsible for patching that.

2:45If I install applications on that server,

2:47I'm responsible, the customer, for patching

2:50those applications.

2:51But once we move to platform as a service and software

2:55as a service, we know that the provider

2:58is managing that software that's underlying.

3:01So they're the vendor.

3:02The cloud service provider is responsible for that.

3:06What about firewall and IPS management?

3:08That's our Intrusion Prevention System.

3:10That's the IPS.

3:10And again, this is our edge security protection.

3:14Well, the thing is if I'm setting this up

3:16in infrastructure as a service, meaning

3:18I'm deploying my own firewall, well, guess what?

3:21In my IPS, I'm responsible for managing those.

3:24But when it comes to platform and software

3:27as a service, where we're building applications and using

3:30the cloud provider's applications,

3:32they're responsible for the edge security that's being done.

3:37What about all the security policies?

3:39Well, this is shared across all of them,

3:42meaning the cloud provider will have their own policies.

3:45But we, as a customer, we should have our policies too.

3:49That's very important.

3:51Policies are super important when it comes to security.

3:55We need to define--

3:56let's say infrastructure as a service.

3:58We're talking about IaaS.

3:59We need to define how we're going to use the IaaS.

4:04What policies are around it?

4:05Do we have policies around who can create

4:08and the creation procedures for cloud services?

4:11We should.

4:12What about platform as a service and our software as a service?

4:16How are we going to use those?

4:17Are we going to use secure coding techniques?

4:19All these things come out in policies.

4:21And then lastly, data encryption.

4:24Now in IaaS, I'm building servers.

4:28If I want to encrypt that data, hey, that's

4:30on me, the customer.

4:31In platform as a service, I'm out there,

4:33and I'm building this app that all our people are

4:36going to use.

4:37Well, I built the app as a customer.

4:40If I want my data encrypted in the app, well,

4:43that's on the customer.

4:44But if I'm using, let's say, some type of HR or accounting

4:51application or CRM application in the cloud,

4:55well, that's on the vendor.

4:56I can't encrypt that as a customer, right?

4:59I don't have access to that kind of thing.

5:00All I can do is use the application

5:03that I'm paying for.

5:04So that falls back to the vendor.

5:06And again, these are just some examples of different features

5:11within the cloud, within IT in general and our services,

5:16in how these are shared responsibilities.

5:19The cloud vendor's responsible for some.

5:21Customer's responsible for others.

5:23And again, this is not like a de-facto standard list

5:27that we see here.

5:28This is just an example.

5:31Because when you go talk to your cloud provider--

5:34you're shopping around trying to find one.

5:36You need to discuss who's responsible for what,

5:40and it needs to be outlined in your contract.

5:42I hope this has been informative for you,

5:44and I'd like to thank you for viewing.

0:06Technology changes every day.

0:08That's just a fact of life.

0:10We know that.

0:11So there's new things like blockchain and quantum

0:14computing and Internet of Things, IoT.

0:17And there's lots of other things too.

0:19But when these things come out, how will

0:22they affect cloud computing?

0:24Now, we have some of these, and they're actually

0:26already being used there.

0:28But how are they being used?

0:30Well, let's jump in and take a look.

0:33We're starting off with blockchain.

0:35And that's one of those newer technologies.

0:37It's been around for a while, but it's still

0:39kind of new to a lot of us.

0:40And it's all about the decentralization of data.

0:45And that's what blockchain is all about.

0:48Now, a lot of people think blockchain is all

0:51about cryptocurrency.

0:53And really, cryptocurrency uses blockchain

0:56to make it so reliable and robust.

0:59But you can use blockchain for lots of different things,

1:02including the cloud.

1:04Now, when cloud first came about,

1:05the idea was that we could take our on-premise assets,

1:10and we could take those and move them to the cloud.

1:14And the idea was in the cloud we have lots

1:15of resiliency and redundancy.

1:17We don't have to worry about power and cooling.

1:19A lot of that was offloaded from our local admins

1:22and our local costs.

1:23So our assets resided somewhere else at a remote data center.

1:28Now, wouldn't it be cool, though,

1:30that if we could instead of putting it in one data center,

1:33we could have our assets copied across different data centers

1:37all over the globe.

1:39And that would provide for lots of redundancy.

1:42Well, that's what blockchain's all about,

1:44decentralization of data.

1:46And what it does is it takes the data

1:48and it puts it in these different locations.

1:51And not only that, built into blockchain

1:54is a way to verify and validate the integrity of the data.

2:00That is super important.

2:01That's what blockchain really is all about.

2:03It's decentralizing data and validating

2:06and ensuring its integrity, that the data hasn't changed.

2:10So if we could use blockchain in the cloud,

2:12our data wouldn't be stuck in one data center

2:15or stuck in maybe two data centers because we

2:17replicate between them.

2:19It would be in multiple data centers

2:21all over the world, individual copies of our data.

2:25And we wouldn't have to worry about data corruption

2:28or tampering anymore because of the integrity.

2:31We would immediately know if a piece of our data

2:34had been tampered with or was corrupted,

2:36and it would no longer be valid.

2:38So we wouldn't have to worry about corruption of data.

2:42It would be a thing of the past because blockchain would just

2:45simply get rid of that data over there

2:48and then copy good data over and replace it.

2:52And that way it's kind of a self-healing environment

2:55at that point.

2:55So that's how blockchain could impact the cloud.

2:59Next up AI-- that's Artificial Intelligence-- and ML, Machine

3:02Learning.

3:03And the idea here is we're using algorithms

3:07to teach computers and programs to identify abnormalities

3:13and to analyze data and look and see what's going on.

3:16And really, a lot of times we like

3:19to integrate AI and ML into security products

3:24because they're very good at identifying abnormalities.

3:29And that's what we look for in security.

3:31What's abnormal?

3:32Does this user normally log in to this server at this time

3:35of day from this location?

3:37And this is how we can really beef up our security

3:39and take it to the next level.

3:41Well, how could AI and ML be used in the cloud?

3:44Well, a lot of times they're used in security services

3:48in the cloud.

3:49When the cloud vendor comes out with a new security service

3:51to help us identify abnormalities and manage

3:54our security, it will include AI and ML in it.

3:57But not only that, they will offer ML and AI services for us

4:04to use.

4:04So when you're looking at platform as a service

4:07and you're looking to build an application, a lot of times

4:09you can use services that include AI and ML as part

4:15of the platform as a service.

4:17So you can use AI and ML in your applications you're developing,

4:20which is pretty darn cool because these oftentimes

4:23come with a large price tag.

4:25So if I wanted to implement this into my on-premise something

4:28or other, I would have to spend a lot of money to get that up

4:32and running in my environment.

4:33But I don't have to in the cloud.

4:34The cloud service provider has already done that

4:37and can provide that service to me, which will definitely

4:41save me a lot of money.

4:42And it makes accessing an entry into the AI and ML world a lot

4:47more accessible.

4:48Next up is containers.

4:50Now, containers are basically-- they're virtual machines

4:54but, I'm going to say, without an operating system.

4:57So they're a virtual machine without an operating system.

4:59How does that work?

5:00How could that even work?

5:02Well, here's how it works.

5:03Really, what we have is we have some type

5:05of content OS or container platform.

5:09And these are things like Kubernetes and Docker

5:13over here.

5:14And the idea is that we would have this container OS

5:17or container platform here and within it we

5:20would run our tiny VMs.

5:22And all these VMs--

5:24which are really containers.

5:25These VMs, or containers, contain an application.

5:30And they can contain the dependencies

5:33that this application needs to run,

5:35and that's all that's in there.

5:37So we don't have an operating system in there.

5:40We don't have a bunch of bloatware

5:41that comes with an operating system and other things.

5:44We just have exactly what we need-- very lean when it

5:48comes to running a container.

5:50So here we could spin up containers,

5:53as many as we need to very quickly, because containers,

5:55they might only need 50 megabytes of memory

5:59in order to run.

6:00And maybe they need 80 megabytes of actual space,

6:04like hard drive space.

6:05So you see, it's very tiny, and that's why they're so popular.

6:10We can spin them up within seconds

6:13because it may only take five to eight seconds for one

6:16of these containers to start up and be usable.

6:18That's a lot faster than a full-blown operating system.

6:22We know it takes minutes for those to get up and running.

6:25So how does this tie into the cloud?

6:29Well, here's how.

6:30Within the cloud, the cloud providers

6:33have taken these container OSes and platforms

6:36and they've put them in the cloud so that you can use them.

6:39You can spin up containers.

6:41But why would we want to?

6:43Well, here's why.

6:44Remember, this is a pay as you go.

6:46It's a metered service.

6:47You're only paying for what you use.

6:49Well, if I'm only paying for this little bit of resources

6:52versus a full-blown virtual machine server,

6:56there's a big difference there.

6:57And when I'm dealing with applications in the cloud--

7:00maybe I have a big database back in here,

7:03and I have a front-end web app that interacts

7:08with my back-end database.

7:09And this is a very static web front end.

7:12So it's just a static web page that people use interact with.

7:16And during certain times of the day,

7:18I need to really spin up a whole lot of these simple web

7:23front ends to handle the load.

7:24Well, isn't it a lot faster to spin up

7:28a bunch of containers, as opposed

7:30to a bunch of full-blown servers?

7:32The answer to that, yes, absolutely.

7:35So maybe I normally run five of these NginX.

7:39We'll say they're NginX containers.

7:41And that's normal.

7:42But during my peak loads, I need to run 50 of them

7:46to meet my client and customer demands.

7:49Well, if I spin up 50 containers, as opposed to 50

7:53virtual machines, hey, it's going to spin up a lot faster.

7:57And I'm going to use much less resources.

8:00So I'm paying for less.

8:02So I get to reduce what I'm paying for,

8:04and I get to respond faster.

8:06Hey, that's a double win in my books.

8:08So this is how containers can affect the cloud environment.

8:14Next up, quantum computing.

8:16Now, quantum computing, if you're not familiar with it,

8:19it uses quantum physics as opposed

8:21to transistors or micro transistors

8:24within a general processor.

8:26So within a general computer processor that we're

8:29used to, a CPU we got over here, well,

8:32they're full of micro transistors.

8:34And a micro transistor is basically a switch.

8:39And a switch is on or off.

8:40So it's 1 and 0.

8:42And this is how we get our binary ones and zeros.

8:46Micro transistors act as a switch,

8:48and they're either on or off.

8:50So here we are definitely limited to how much data

8:54we can store and process.

8:56Well, with quantum computing, it actually uses

9:00quantum physics instead of our micro transistors,

9:05which means it can store not just ones and zeros,

9:09but it can actually store multiple values.

9:13So if we are able to get these up and running like science

9:17says they should be working, then we

9:20will have amazing processing power.

9:23And quantum computers have already been created,

9:26but they're not yet quite to the mind-boggling compute power

9:30level.

9:30So how does this tie in to the cloud?

9:32Well, some cloud providers, they've already purchased

9:36and have quantum computing--

9:39put a Q there--

9:40in their environments.

9:42Well, why does that matter?

9:44Well, here's why it matters.

9:45They can offer you access to these as a service.

9:49Could you imagine how much these are costing right now?

9:51I have no idea.

9:52But I would say it's a whole lot.

9:54Anytime a new technology comes out, it is extremely expensive.

9:57So that means most organizations cannot afford to use it.

10:00But what if you just wanted to do testing with it,

10:03or you wanted to run your application through it for half

10:06an hour, a day, whatever it might be?

10:08Well, then you can go to your cloud service provider.

10:10You can sign up for their quantum computing service

10:13and only use as much as you want to because, remember,

10:16you're only paying for what you use.

10:18So this is a way for cloud service providers

10:21to allow an entry level, an easy way to gain access to,

10:25and an affordable way to gain access to quantum computing.

10:29And lastly, IoT, Internet of Things.

10:33Now, the internet of things are all those smart devices

10:36out there.

10:37They could be a smart phone, your smart light bulbs,

10:41smart houses, Wi-Fi devices, all kinds of things,

10:45our smart thermostats.

10:47All of those things are referred to as IoT devices.

10:51OK.

10:51Well, that's nice.

10:52But how does that relate to--

10:54yeah, you guessed it.

10:55We're tying it back to the cloud.

10:56How does it relate to the Cloud well,

10:58we need something to manage all of these devices.

11:03And guess what?

11:04Cloud providers, those CSPs out there,

11:06they've already done this.

11:07They've provided IoT as a service.

11:13So you can actually go out to them.

11:14I know AWS has it.

11:16And you can sign up, and you can start using their services.

11:19So what you can do is you can create applications that

11:22will run on these IoT devices.

11:24And you can manage them and collect data

11:26and do what you need to.

11:27So instead of trying to create an IoT infrastructure

11:30from scratch and figure all that out, there's no need to.

11:33You can go to your cloud provider

11:35and use IoT as a service.

11:37That's a new type of thing so that you

11:40can create and deploy and manage your own IoT environment, which

11:43is pretty darn neat.

11:44And really what it comes down to is

11:46all these new technologies and things,

11:48it is a way to access them.

11:51The cloud provides us a way to access them,

11:54and not just the cloud itself per se,

11:56but those cloud service providers.

11:59The providers are going out there.

12:01These CSPs, the larger ones, they have a lot of resources,

12:04and they can go out and they can gain access

12:07to these new technologies.

12:09And they can deploy them as a service

12:13so that we as consumers can gain access and use

12:17these new technologies to our benefits

12:19without going out and creating the huge environment so we

12:22can support them.

12:23We can just tap into the resources

12:27that the providers are providing us with.

12:30So this is really darn neat.

12:32And it's a great way to get started in some

12:35of these new technologies.

12:36I hope this has been informative for you,

12:38and I'd like to thank you for viewing.
