2.5 vCenter Server Overview

00:00

Hi, you're watching model to yes, X. I envies Inter server

00:05

lesson for V Center server Overview.

00:08

By the end of this video, you'll understand V centers, architecture and components.

00:13

You'll know what installation options you have and the installation type you should go with.

00:18

Let's begin.

00:19

You should already know what the center is. If not, I encourage you to go watch Model one Lesson three,

00:26

but we're gonna review it anyway.

00:28

V Center is Veum. Where's centralized management platform?

00:32

It simplifies management at scale.

00:35

What I mean by that is, if you have, for example, a bunch of years Excite House and you want to perform routine management or monitoring, you'll have to log into each year's excise separately, using the host client or the Yes Excite Shell.

00:47

Either way, you'll be connecting to a native management agent called Host Day.

00:53

Now, imagine having dozens or even hundreds of hosts.

00:56

Are you gonna manage them separately?

00:58

Good luck with that.

01:00

It's obvious that this does not scale very well

01:03

with the center. On the other hand, you establish a single session to a Web interface from which you can manage all your years Excite house.

01:11

In fact, the center will roll out an agent called V P X A on every year's X I, and then it uses a single native agent called V P X D to manage them all.

01:22

This Federated Architecture is what makes resent a very convenient

01:26

reasons. Also brings advanced features that are not available. Otherwise,

01:32

it lets you create a cluster.

01:34

Now the cluster is an object that group CSX I hosts for the purpose off, enabling features like high availability, DRS and many others.

01:44

In fact, you can create multiple clusters and enabled different features on each

01:49

Another cool feature is the update manager.

01:52

Imagine having hundreds of his Ex I house

01:53

and a bunch of them are running on different versions off years. Exile.

01:59

This is most inconvenient because some futures will be available on some house, but not on the others.

02:05

In addition to support tasks, becoming a nightmare

02:08

update Manager keeps all your years excites hers up to date with regards to patches on New Year's Excite version roll ups. So it leaves you with the tidy place to work with

02:19

pretty awesome.

02:21

This makes you want to install recent doesn't it? Which brings us to the installation times

02:25

as off the current release office Fear, which is six or seven. The center can be installed in three fashions

02:31

on a physical windows machine on a virtual windows machine

02:36

or on the virtual clinics machine, also known as Visa. Enter server appliance,

02:42

the first to have bean deprecate ID way back in 2017 that they are still available to install. However,

02:50

in the next major release off the sphere, the windows installation will disappear and will no longer be supported

02:55

For all those who are still running V Center and Windows VM, where have long provided a migration tool that converts or installation into an appliance installation.

03:06

Now the Windows installation has been abandoned for a number of reasons. Among guage the fact that it is not cost effective

03:13

since you have to pay for your Windows license, the database license and V Center license.

03:17

The appliance option is what Liam, where recommends, and it is the only option that will survive.

03:23

It is a low cost alternative, since re center will run on an open source Lennox based operating system called Photon.

03:32

It was developed by Vienna.

03:35

It also uses an embedded open source pasta grass database, so you only pay for the center licensing

03:42

visitor Server appliance has two main components. You must be aware off

03:46

the platform service's controller or PSC, and the reason to serve itself each one of them is similar to a rolled in Windows server. If you ever worked with Windows seven before, the platform service comptroller is a set of shared infrastructure. Service is that include a single sign on service or es eso,

04:05

which is the authentication service

04:08

that gives you or denies you access to the center? According of course, to your user permissions.

04:14

SSO also lets you to link and external identity source like active directory or held up.

04:20

The PSC also comes with the certificate authority to secure connections and a licensing service that keeps track of flu licenses.

04:29

And, of course, many other service is that I'm not listed here.

04:32

The V's enters ever includes a set off service is on its own, including the V Center Server Management platform,

04:40

which is represented by the V. P X d Service, a possibly list database that stores the configuration off all your hosts. Viens on futures.

04:48

Think of it as the meta data off all your data center.

04:53

And by the way, it is also possible to use an external Data banks instead of the embedded one.

04:58

And then we have the Web client, which is a Web interface into V Centers inventory.

05:02

It was developed using the late Adobe Flex Sdk, which is based on Adobe Flash.

05:09

Now the Web client has been duplicated recently and will be completely removed from the next major release off East Fear, because Adobe decided to abandon Flash by 2020.

05:19

Now the successor to the Web client will be the V's for a client.

05:23

It serves the same purpose, but it is based on HTML five. Instead of flash,

05:28

Visa for Client was introduced in V. Sphere six top five

05:31

and will remain as the only client supported in the coming releases.

05:36

Visitor also contains the Auto Deploy Service, which lets you install years excite on hundreds of service at the same time.

05:44

Okay, now let's recap.

05:46

V Center server can be installed in three different fashions on the physical Windows machine on the virtual windows machine or as a virtual Lennox machine called Appliance.

05:58

The Windows installation has been depreciated, and so the appliance is the way to go.

06:02

V Center has two main components. The PSC, which is the authentication role, and recent a server, which is the management role.
