1.4 Module 1 Summary

00:01

this brings us to the end of March alone.

00:04

Let's recap.

00:07

First realization is a technique that abstracts physical resources of server and then shares them among virtual machines.

00:15

A virtual machine is similar to a physical machine, except that it is a guest off another operating system called the hyper visor.

00:24

Virtual machine is also hardware independent and can run on any server with a high provided

00:31

Now the hunger Visor shares. The physical resource is among virtual machines,

00:35

so every VM gets a fraction off the total resources, and we call that fraction. Virtual resource is

00:43

obvious. Fear is Veum Ware's flagship product for server virtualization that's made up off the hyper visor called US Excited

00:51

and a management platform called V Central Server. Plus a bunch of interesting features.

00:58

No.

00:59

Before we end this model, let's make sure you digested it well.

01:03

Here are a couple of questions for you.

01:07

First question. What are the benefits off organization?

01:11

Is it a application Consolidation?

01:14

Be application isolation?

01:17

See

01:18

both

01:19

or D service prole.

01:23

Second question.

01:23

What are virtual resources?

01:26

Is it a imaginary resource? Is

01:30

be physical. Resource is

01:33

see a fraction off physical resource is or D none of the above.

01:40

Third question.

01:42

What his V Center server?

01:44

Is it a VM wears hyper visor?

01:47

Be a future off these fear.

01:49

See a management platform for your six. I cursed

01:53

or D None of the above.

01:57

Fourth question.

01:57

What the sphere feature lets your migrates of powers on virtual machine without downtime.

02:06

This is a

02:07

this fear of emotion.

02:08

Hey,

02:09

fees, fear, high availability.

02:12

Saying this fear DRS

02:15

or D None of the above.

02:17

That's a tricky one.

02:20

Now pause the video and write down your answers, because I'm giving you the correct answers in the next slide.

02:30

Here are the answers, but let's review them

02:34

now. Question. Number one Victory Ization lets you run multiple applications within the same server, and that's what we call consolidation. So answer is actually correct.

02:45

But it also isolates them because each application runs on its own virtual machine.

02:51

And that's what we call isolation. So answer B is also correct.

02:57

Now service pro means underutilization off computing resources, and that was actually a problem that visualization solved. So that's why answer C is the correct one.

03:08

Let's go to a question Number two.

03:12

The hyper visor gives every original machine its own share off the total physical resources available.

03:17

The virtual machine cannot monopolize the hardware,

03:22

so each VM gets a fraction off the physical resources. And that's what we call virtual. Resource is. So answers, see, is the correct one.

03:30

Question number three

03:32

V Center is a cornerstone off these fear along with yes, exile. Now we have seen that Vienna, as hyper visor is called Yes, Exile. So answer a is wrong.

03:45

Re center is not the future of issue. It is actually a feature in neighbor,

03:50

and he's not a future itself.

03:52

Most features cannot be used without the center. So the center is the management, huh? For the sphere. And that's why answer C is the correct one

04:02

question for

04:04

this one is a little bit tricky

04:06

now. Migrating powered home virtual machine from one server toe Mother is a great feature of the sphere, and remember, it is called the motion,

04:16

and it is manually performed by an administrator, so answer is correct.

04:21

Now the sphere high availability does not migrate. Virtual missions. Itjust restarts them on another server after they power off due to a server failure. So answer B is actually wrong

04:36

Now we've talked a little bit about fi sphere, DRS. And what it does is migrating powered on virtual machines from one server to the other in order to balance the computing load between service.

04:51

Look at it this way. DRS. Isn't automated the emotion.

04:56

So that's my answer. C is also correct.

05:00

That's you.

05:00

I hope this was informative for you.
