So the next thing that we're gonna talk about is how
the V sphere technology of'em wear fits into a cloud environment.
We don't spend a lot of time talking about this in this class.
other classes related to
VM wears cloud solutions.
But the first thing you want to think about is the different types of clouds,
so I can have a private cloud
and I can have a public cloud.
And then there's also
So in the case of a private cloud,
most often what this is talking about is some organization.
Besides that, they want to use cloud technology where they access their applications, and all of their service is
basically through Web browser through a Internet connection.
But in this case, the cloud is dedicated to that. That organization on Lee,
they don't share it with anyone,
and this this provides the greatest level of security and control over how that cloud is used.
Ah, public cloud, on the other hand,
might be accessed by multiple organizations.
this is called a multi tenant environment, sort of like a multi tenant building. Either it's a a private building where one family lives in it or you live in an apartment where there's multiple tenants. Similar concept,
Uh, and so the advantage of of the security of afforded here is offset somewhat by
He reduced expense of typical public cloud
and, ah, hybrid, then
would mean that the private organization
some other applications and their private cloud and perhaps some of them
through the public cloud,
so you can have a, ah, split,
a little more flexibility to organizations. They want to keep certain things in the private cloud
and other things in a cloud that's public. So we have a little more flexibility with how the user's access the data.
Several advantages to using the cloud environment.
For one thing, depending on how you got a configured
users or administrators can provisioned their own resource is to some extent,
grow and shrink those resources,
and we'll recall that elasticity.
So if I can grow and shrink my resource requirements
on on a moment to moment, they says that provides a truly useful tool for the administrator
to deal with a rapidly changing
demands on storage, networking and provisioning. New servers.
It also provides the ability to do rapid deployment of of new solutions.
server, you can clone it. You can
clustering and continue to build our capabilities as required by
your organization's needs.
Also, if we think about
in the private cloud, especially if I've got
and I, uh, let's say I've got, you know, 10 hosts here.
If those were the traditional data center,
And if they were physical servers, I would have to think about
what applications can I put on host number one? What once can fit on number two
and so on down the line? If I cluster these host together, I can then share. The resource is more effectively
to fully utilize them in a physical host environment. Quite often
you have unused capacity,
so someone buys a server. They put the applications on it. They it's up and running,
but maybe they're not using all of the available memory. They're not using all of the available processor capacity.
and a less here for APPA Nola's.
Then I can share. The resource is more effectively and probably get a higher consolidation ratio.
Which is another way of saying how many applications cannot run on one system at one time.
If I had a physical server, maybe I could run two or three large applications.
But if I virtualized everything, I might be able to run for five or 10.
It just depends on how you got to configure.
All right, so at this point we talked about some of the differences between physical and virtual machines.
We defined a virtual machine as having
applications with a guest, no West
virtualized running through the hyper visor, which translates the instructions
threw down through to the physical host.
We also talked about how the resources are shared
among the virtual machines running on the physical host
and touched ah, little bit on the concept of the private cloud, the hybrid cloud and the public cloud.
So that concludes Lesson one for Module two,
and the next lesson will be discussing the different interfaces for user's into the beast. Fair environment
