In this chapter, we emphasized the importance of virtualization and containerization.
We showed you the difference between VMs and containers. You learned how to deploy a VM using KVM. We also showed you how to quickly create a VM inside GNOME using Boxes. With those two assets, you are prepared to start your path into virtualization with no fears. We also showed you what containers are, how they work, and why they are so important. Containers are the foundation of the modern DevOps revolution and you are now ready to use them. We also taught you about Docker, the basic commands for a sleek use. You are now ready to start the cloud journey, as this will be the final part of this book.
Virtualization and container technologies are at the heart of cloud technologies. This is why, in the next chapter, we will introduce you to the basics of cloud technologies, OpenStack, AWS, Azure, Ansible, and Kubernetes.
