1
00:00:00,210 --> 00:00:07,800
It's very seldom today that companies run individual servers on individual hardware.

2
00:00:08,130 --> 00:00:17,580
What tends to happen is that a virtualization software such as VMware or KVM is used to virtualize hardware

3
00:00:17,580 --> 00:00:19,470
for multiple servers.

4
00:00:19,860 --> 00:00:28,170
In other words, you can run multiple servers on a single bare metal PC or bare metal server.

5
00:00:28,970 --> 00:00:31,040
For example, I'm running.

6
00:00:32,720 --> 00:00:34,430
Mac OS here.

7
00:00:35,620 --> 00:00:39,160
But I'm also running Linux in a VM.

8
00:00:39,160 --> 00:00:43,570
In this example, I'm running the S3 VM on my Mac.

9
00:00:43,840 --> 00:00:46,180
The Janus three VM runs on Linux.

10
00:00:46,690 --> 00:00:57,010
I've also got a Windows PC that I could boot up and run within VMware on my Mac in the same way on the

11
00:00:57,010 --> 00:00:58,210
Windows PC.

12
00:00:58,240 --> 00:00:59,710
I could boot up.

13
00:01:00,470 --> 00:01:01,910
The genus Trivium.

14
00:01:03,090 --> 00:01:04,920
Which runs on Linux.

15
00:01:07,350 --> 00:01:11,850
I could also boot up other virtual machines running in the virtual box.

16
00:01:13,080 --> 00:01:13,980
As an example.

17
00:01:13,980 --> 00:01:21,300
This is a Linux based operating system running within a virtual box within a Windows PC.

18
00:01:21,930 --> 00:01:25,140
So I could run multiple hypervisors.

19
00:01:26,490 --> 00:01:27,600
On Windows.

20
00:01:28,650 --> 00:01:35,550
So I could, as an example, like I'm doing here, run multiple hypervisors on windows and run multiple

21
00:01:35,550 --> 00:01:37,830
operating systems within Windows.

22
00:01:37,950 --> 00:01:39,630
Typically you don't want to do that.

23
00:01:39,630 --> 00:01:47,910
Typically you run one hypervisor at a time on your Windows operating system or on your Mac operating

24
00:01:47,910 --> 00:01:48,510
system.

25
00:01:48,960 --> 00:01:57,180
The advantage of doing it this way is that you can run applications that require different operating

26
00:01:57,180 --> 00:02:00,840
systems on the same server or the same PC.

27
00:02:01,880 --> 00:02:09,620
So as an example, GNC has an application to provide better functionality requires that I run Linux

28
00:02:09,620 --> 00:02:16,640
within a virtual machine to support certain types of devices in a gene S3 topology.

29
00:02:18,570 --> 00:02:20,040
So as an example.

30
00:02:20,790 --> 00:02:30,990
If I want to run iOS devices such as an iOS via a layer two switch or an iOS router that needs to run

31
00:02:30,990 --> 00:02:32,880
within the three VM.
