all right now, we just spoken about this special publication 800 death 1 45 and that just provided us with the definition for cloud computing. Now we're moving on to the Cloud Computing Standards road map.
Okay, And the next couple of slides air from that road map, which is more formally known. Its NEST
Special Publication 500-291
Special Publication 500-291 That's the road map. And that's probably if you had nothing else but that one document.
If you knew everything in it and understood it well, you would pass the exam, but it's that important, and I would not even dream about taking this exam without looking through that. Okay, so again really encourage you? I've tried to pull out those most significant elements,
but it's best if you sit down and read it in its full entirety. It's not like it's 1000 pictures. It's very readable document.
All right to the first piece, five characteristics of cloud computing so earlier I said, Well, the cloud is just somebody else's computer, right?
Yeah, you know, I mean, we can say that, but to officially be considered an element of cloud computing there. Five characteristics that must be satisfied. And this is Pernice. So broad network access
certainly say that of the cloud, right? We're not worried about, you know, resource is we're not worried about band with. We're not worried about the computing power. We're not worried about those elements. We have access to band with two technology to the tools that we need.
So we're essentially unlimited, at least on our cloud service providers and
broad access
on demand. We've already talked about that quite a bit, right? Pay as I go use what I need, I can add or release service is without having to involve cloud service provider. So I'm in charge and I can add, Remove, modify, you know, reconfigure the network very, very quickly.
Resource pulling for resource pulling toe work. We have to have virtual ization and again taking all of the elements on this system and using them together. Right? Pulling all of these resource is and making them available to the end users to the customers
measured or meter service's
pay What you use. It's not a flat fee every month, unless you necessarily particularly like buy a package or whatever that may be. There are instances where there's flat fee every month, but for the most part I'm paid based on I pay based on my usage. Now that depends more if it's software is a service or
infrastructures of service. But that's a benefit, right?
Pay for what you use and don't pay more. Don't pay less either. And then last rapid elasticity.
A lot of times, you'll hear that scale, ability, the ability to increase decrease resource is is need.
so over on the next slide, I just have a little visual that kind of help us see these characteristics, this idea of on demand self service, utility based billing. Um, uh, basically, nothing is new here.
This might be a good screams, a good slide to screen shot just so that you have kind of those key elements that are most important, right? So nothing new here. This is exactly what we talked about. Four. I've just kind of giving you just short and sweet little details and the picture because we like pictures.
Okay, we'll move on to the cloud actors in just a moment
