The authors walk us through the installation of each of the products in detail(they even include screenshots of the installation process) in the first chapter. In the second chapter, they cover different types of storage and how to use them in an ESX environment. In the third chapter, they cover recipes for configuring networking for ESX. In the fourth chapter, they cover the important topic of resource management.
What I really liked about the book is that in the fifth chapter, they present a bunch of really useful command-line tools.
I wish they covered at least a part of the different APIs (for example: vSphere PowerCLI) that are provided by VMware but may be they plan to cover these in a future edition of the book.
