If you want to know the answer to those questions, I’ve made that video just for you!
This video is designed to be a self-contained introduction to virtualization and related concepts. I do not cover the specific installation or configuration of any given solution here. I only focus on the concepts.
After having watched that video, you’ll be able:
to quote several use cases for virtualization, both at home and in the enterprise world;
to describe the role of an hypervisor/VMM;
to identify the difference between type 1 and type 2 hypervisors—and to consider that distinction with all the cautions deserving a theoretical tool that dates back to the 70s;
to mention the key differences between a virtual machine, an emulator and a container;
to explain why virtualization was a cornerstone of the cloud computing development.
