This book is intended for those who want to know the secrets of virtualization and how network services provide high availability.

If you are a beginner, this book also gets you up to speed on what is happening from conception to implementation. For this book, it will be better if you have some experience in network and system administration, while experience in Proxmox is not necessary.
