00:00:00,000 --> 00:00:11,240
In this video, I want to talk about the relation between virtualization and cloud.

2
00:00:11,240 --> 00:00:12,240
So how does it work?

3
00:00:12,240 --> 00:00:16,360
Well, a virtual machine runs on a host operating system.

4
00:00:16,360 --> 00:00:20,780
Virtual machines can also run in cloud, and that brings the benefit that they don't depend

5
00:00:20,780 --> 00:00:23,879
on one physical host, but they can run anywhere.

6
00:00:23,879 --> 00:00:29,000
A virtual machine that runs in a cloud is typically referred to as a cloud instance.

7
00:00:29,000 --> 00:00:33,799
An essential property of virtual machines running in the cloud is decoupling.

8
00:00:33,799 --> 00:00:34,799
What does that mean?

9
00:00:34,799 --> 00:00:39,720
Well, that means that while your virtual machine runs in the cloud, it doesn't depend on anything

10
00:00:39,720 --> 00:00:41,840
specific on the host platform.

11
00:00:41,840 --> 00:00:46,560
So it can be moved around, and if one host crashes, it can easily be started somewhere

12
00:00:46,560 --> 00:00:48,080
else.

13
00:00:48,080 --> 00:00:52,520
And decoupling makes it easy to deal with virtual machines in a flexible way.

14
00:00:52,520 --> 00:00:56,759
And that is why so many companies are using cloud-based software nowadays.
