Video Transcription

00:04
Welcome back to sobriety. I am just a Lingam. Today we'll be covering virtualization virtualization. We're going to be covering the benefits of actualization, migration and the considerations when it comes to migration
00:16
benefits. Virtualization Want to talk about shared resource is Latsis City. When we talking about isolation and infrastructure, consolidation
00:24
showed Resource is for shared resource. Is the provider will give the customer resource is as they need it, but it's also based on the share, so therefore, what you might be using somebody else might be using. Also,
00:38
sharing resources over the cloud provides better efficiency, while reducing costs is also a call savings. Where, if admin department and Business Department are getting their service, is from the cloud they might be sharing. Some resource is the CPU, memory or disk space, so that away they're able to provide
00:56
better cost savings to the company as a whole.
01:00
Elasticity lattice ity is a term used to give. The customer resource is loosely. Basically, they will get a little bit of resource is, but then,
01:08
as things change, that will take those resources away, or if they need more processing power than give them more as they need it.
01:17
Authenticity has also used for cost savings.
01:19
Isolation is a separation of resource. Is this where the provider will separate? The resource is so that way they're able to give specific resource is too specific companies or departments as needed.
01:32
It's also used for separation of traffic. The provider will separate the traffic so that away, more information is falling in the Craig ways. The I T department might need more band with because they're doing more programming or they're doing more. Resource is on that end, whereas at the end of the year, the accounting of Business department might need more been with
01:49
for the Ice Lake traffic and give them more bandwidth for that situation.
01:53
Infrastructure consolidation is
01:57
consolidating many virtual computers on a single host.
02:00
With virtual machines, you're able to
02:02
provide many computers on one host. The purpose behind that is to get rid of the overhead. Why would you purchase 10 computers and then put them on in 10 separate rooms? Whenever you can have one server and that one server can provide 20 computers to all the rooms,
02:23
its uses, less power and fewer admin functions
02:25
again for saving time.
02:29
If there is one problem on one PC. Whenever an administrator fixes that problem, that takes away time from them from whenever they could be working on something else. Something on the servers updating the servers are making sure that they're okay. Migration on migration. There's a few things we're gonna talk about. We're gonna talk about the template. We're also going to talk about
02:46
moving from virtual machines to physical servers or moving back to virtual machines
02:51
and the reasons why you do that. We're also going to talk about cloning template. A template is the baseline of an actual PC. The purpose behind a template is so you have a blueprint of what it is that you're supposed to follow. You know that you and saw the operating system. Then you load the protections, and then you might load something else onto the machine.
03:09
Next time we talk about is virtual virtual.
03:13
The reason why you'd want to do a virtual virtual. It's that a way you can copy machine to another machine. People that are working inside the network,
03:21
they're gonna be using a generic copy of a Windows machine,
03:24
and the virtual virtual allows you to do that, allows you to give one person the exact same, Think said away. If there is an issue, you know that it has to deal with these people. So therefore you can take that issue, modify it and then give it back to the customers that away they're able to do the proper work with virtual virtual, you're also able to automate the process.
03:44
This allows the administrator
03:46
to start the process and then walk away so that where they can perform other functions.
03:51
Next thing we're gonna talk about its physical. A virtual physical virtual is usually a migration from physical servers or physical machines to virtual servers. This has to do with consolidate. The last thing we're gonna talk about is virtually physical. Virtual physical
04:05
is a downgrade. However, The reason why people would want to go from virtual to physical is because certain applications might not work correctly on a virtual machine. Say, for instance, years and some type of packet sniffer with that packet sniffer, it is taking in packets from the network,
04:20
but it might not work correctly on a virtual machine, and it needs to be round on a physical standalone machine
04:27
to actually work and do the features that needs to do This will be a reason as to why you would want to move from a virtual machine to a physical machine. And a lot of times, whenever you move from a virtual machine to physical machine, you're going to perform some sort of test inside that physical machine. Veum Cockney them Cloning is whenever you create an exact copy of a machine
04:46
later on and cloud Plus, we want to talk about imaging and imaging is using cloning.
04:50
Cloning allows you to create an exact copy of one machine and put it on another machine. The purpose behind that is so you can have a standard inside of your network.
04:59
You don't want to have every machine a little bit different. You want every machine to be the same so that away, whenever you're troubleshooting or you're performing steps or it's time for an upgrade, agreeable to do the exact same thing every single time. The next thing that we're going to talk about is migrating considerations. We don't talk about the upgrade requirements, maintenance and testing
05:19
upgrading.
05:20
Whenever it comes to V EMS, you have two machines that need to be upgraded you have the host of that machine and you have the Veum itself that need to be upgraded.
05:30
Whenever you're up wearing this machine's you take that consideration. If you're upgrading the host, and the host said that needs a reboot after that, well, then that means that all those Veum said the hostess hosting are going to go down. So you need to take that in consideration. They need to schedule proper mating. It's time to be able to shut those machines down. Also, whenever it comes to upgrading the hopper visor
05:49
might need to be upgraded itself.
05:51
Updates and patches do come out
05:55
and you need to take that consideration requirements.
05:58
Whenever it comes to
06:00
the EMS, you need to make sure that the actual server or the machine will be able to run you. Also, you make sure that the operating system that you're going to be running the VM with needs to be able to host that Veum properly. You don't want to spend thousands of dollars just to find out that you need additional equipment or that you need additional service is
06:18
so
06:19
making sure that the VM will properly run and that you have all the cables that you might need is very important whenever it comes to upgrade. Another thing you need to do is clean up the machine before you actually start the migration. If it's possible to make a clone and my great 10 gigs versus 20 gigs,
06:40
you want to make sure that you're able to make that clone is smallest possible so that where you're using less space, less CDs, less DVDs or less hard dress base. If you're doing it that rap maintenance need a plan for maintenance accordingly
06:51
implanted maintenance. You make sure that your chain of command is aware of the situation and that they're not going to be blindsided whenever it comes to the servers being down.
07:00
But the service go down, you're going to create an outage, and as an administrator, you want to make sure that your allergist are kept to a minimum. Also, whenever it comes to maintenance, you want to make sure you have milestone set in place. If you're going to be migrating server into the network, you want to make sure that you have milestones that on this day you're going to load this. This they were going to load that
07:20
Tessie
07:21
testing is very important whenever it comes to upgrading machines or or moving from virtual virtual gonna make sure that the users are able to perform the functions that they need to perform. I would hate to be in a situation where I spent weeks working on a server getting it up to date. But then it turns out that the program that I installed
07:39
didn't actually work, that the user's weren't actually able to perform the functions that they needed to perform.
07:44
That's where testing comes into play. You create a small server, you create a small network. You you install what you need to install, and then you test it out and you allow the users to come in and test that what they need to test out. Also, whenever it comes to the final steps, she wants to reboot the servers and make sure the servers come back online in a proper state.
08:03
Not only that, but the backups You want to make sure that the backups are able to restore
08:07
and that you're able to perform a backup before and after the testing in case a disaster happens and this module recover benefits virtualization migration, migration considerations. My name is just laying on this summary. I t.
08:20
And I hope you guys learned a lot.
