Summary

In the previous chapter, we mentioned how to prepare a machine that we can work with throughout this book. An alternative to that is using cloud instances, with which we could be consuming virtual machine instances from the public cloud, which may simplify our consumption and provide us with enough free credit to prepare for RHCSA. Also, once the self-training process is complete, the machines can be still used to provide your own public services (such as deploying a blog).
