In this video, I want to talk about the relation between virtualization and cloud.
So how does it work?
Well, a virtual machine runs on the host operating system.
Virtual machines can also run in cloud, and that brings the benefit that they don't depend
on one physical host, but they can run anywhere.
A virtual machine that runs in a cloud is typically referred to as a cloud instance.
An essential property of virtual machines running in the cloud is decoupling.
What does that mean?
Well, that means that while your virtual machine runs in the cloud, it doesn't depend on anything
specific on the host platform.
So it can be moved around, and if one host crashes, it can easily be started somewhere
else.
And decoupling makes it easy to deal with virtual machines in a flexible way.
And that is why so many companies are using cloud-based software nowadays.
