Summary

In this chapter, we provided a quick overview of the methods for creating a virtual machine. In my opinion, the easiest and fastest way is to rely on the use of pre-built cloud images. In a couple of steps, and with enough practice, we can have them working in a matter of minutes.

For example, we can use them for persistent storage, self-management, or even to delegate a containerized service as a system service managed by systemd.
