1
00:00:00,670 --> 00:00:01,390
Well, hi, guys.
2
00:00:01,750 --> 00:00:04,210
In this video, we're going to learn virtualization.
3
00:00:04,930 --> 00:00:06,550
So I want to get started real quick.
4
00:00:07,620 --> 00:00:14,250
So the virtual server and this has actually become an indispensable device for corporate data centers.
5
00:00:14,790 --> 00:00:16,740
It's thanks to virtualization.
6
00:00:17,700 --> 00:00:22,560
Well, that we've actually been able to overshadow these physical servers now.
7
00:00:22,680 --> 00:00:27,480
Don't worry what you just learned is still relevant, but we're going to take it a step further.
8
00:00:28,630 --> 00:00:33,380
Because the virtual server does not make its physical counterpart unnecessary.
9
00:00:34,270 --> 00:00:39,970
So you both have their benefits and ideal usage scenarios, so to better understand the difference between
10
00:00:39,970 --> 00:00:46,090
a virtual server and a physical server, it's necessary to examine each one by itself.
11
00:00:47,180 --> 00:00:53,720
So virtual servers, they require physical servers to operate, but they are different from physical
12
00:00:53,720 --> 00:00:57,050
servers running a web architecture database or file server.
13
00:00:58,380 --> 00:01:01,500
All right, so what is a physical server again?
14
00:01:02,430 --> 00:01:08,430
Well, a physical server is the hardware with a motherboard or processor or memory and Io controllers,
15
00:01:08,460 --> 00:01:09,360
all that kind of stuff.
16
00:01:09,360 --> 00:01:15,870
It's hardware, and it's used directly by an operating system rather than a virtual platform.
17
00:01:17,410 --> 00:01:22,540
The physical server is reference to run a single instance of an operating system.
18
00:01:23,450 --> 00:01:30,290
It's the physical servers that are used to run Windows and Linux or another operating system and often
19
00:01:30,290 --> 00:01:32,030
a single application on it.
20
00:01:33,420 --> 00:01:37,200
OK, so then what is this virtual server?
21
00:01:38,010 --> 00:01:39,120
Does it even exist?
22
00:01:39,870 --> 00:01:45,810
Well, yeah, a virtual server or virtual machine is software based.
23
00:01:46,290 --> 00:01:50,400
It's a software based representation of a physical server.
24
00:01:51,550 --> 00:02:00,370
The technique that abstract CPU and memory storage and network resources from the underlying hardware,
25
00:02:01,090 --> 00:02:05,440
and it assigns him to virtual machines or a VM.
26
00:02:06,430 --> 00:02:11,170
A virtual machine can also be referred to as hypervisor.
27
00:02:12,320 --> 00:02:12,710
Yeah.
28
00:02:12,890 --> 00:02:19,340
Because the hypervisor runs directly on the servers, hardware, not on an operating system.
29
00:02:21,260 --> 00:02:27,380
So virtual machines have an additional level of isolation, and they can run a standalone operating
30
00:02:27,380 --> 00:02:29,540
system on the hypervisor.
31
00:02:30,730 --> 00:02:38,410
So a physical machine can be divided into many virtual machines, each of which has its own purpose.
32
00:02:39,370 --> 00:02:39,830
Wow.
33
00:02:40,120 --> 00:02:41,470
That's like totally cool, right?
34
00:02:42,280 --> 00:02:43,180
So let's go on.
35
00:02:43,750 --> 00:02:50,020
Virtual servers can allow organizations to more effectively allocate their physical hardware resources
36
00:02:50,350 --> 00:02:51,730
to ongoing workloads.
37
00:02:52,720 --> 00:02:58,720
And this is because virtual servers can exist in the same physical environment as opposed to physical
38
00:02:58,720 --> 00:02:59,230
servers.
39
00:03:00,170 --> 00:03:07,820
While a physical server is a single tenant platform with dedicated resources, a hypervisor can support
40
00:03:07,820 --> 00:03:16,340
multiple virtual servers, allowing multiple applications to run concurrently and share physical hardware
41
00:03:16,340 --> 00:03:17,840
capacity among themselves.
42
00:03:20,660 --> 00:03:26,660
So in addition to more efficient allocation of hardware resources, virtual servers offer businesses
43
00:03:26,660 --> 00:03:27,650
a number of benefits.
44
00:03:28,430 --> 00:03:31,400
For example, virtual servers are often easier to manage.
45
00:03:32,430 --> 00:03:38,550
While some companies may choose to set up virtual servers on physical servers stored on site, while
46
00:03:38,550 --> 00:03:45,270
many businesses work with managed service providers who manage their virtual servers for them.
47
00:03:46,520 --> 00:03:52,910
Now, in the second scenario, the maintenance, updating and management of servers is all delegated
48
00:03:52,910 --> 00:03:59,540
to trained data center specialists and businesses then don't even have to bother to keep servers up
49
00:03:59,540 --> 00:04:00,740
and running and cool.
50
00:04:01,580 --> 00:04:08,870
So this model also makes virtual servers highly scalable and even immediately think about like this.
51
00:04:09,920 --> 00:04:15,830
When businesses with physical servers want to add more capacity, well, they need to go out and request
52
00:04:15,830 --> 00:04:21,650
new hardware, work with IT professionals to prepare that hardware for their internal use.
53
00:04:22,070 --> 00:04:26,990
Maybe even add some more air conditioning or, you know, all of that stuff.
54
00:04:27,970 --> 00:04:34,960
But with virtual servers, hey, capacity can be easily added or scaled down as needed.
55
00:04:36,700 --> 00:04:43,090
So virtual servers are a critical component of business continuity and disaster recovery strategy.
56
00:04:44,120 --> 00:04:50,390
So whether businesses are running on premises, virtual servers and using cloud storage backup or using
57
00:04:50,390 --> 00:04:53,870
providers located far from natural disasters.
58
00:04:54,230 --> 00:04:59,210
Well, virtual servers help restore services with minimal downtime.
59
00:05:01,310 --> 00:05:02,060
So what do you think?
60
00:05:02,540 --> 00:05:03,650
That's pretty cool, huh?
61
00:05:04,190 --> 00:05:10,310
So now you know about virtualization, you also know the difference between physical and virtual servers.
62
00:05:11,390 --> 00:05:16,190
So I hope you're excited about this as I am, you know why?
63
00:05:16,760 --> 00:05:18,410
Because we've got more in the next video.
64
00:05:19,010 --> 00:05:19,760
I'll see you then.
