First and foremost, we must express our gratitude to our families for supporting us while writing this book. Both of us wrote and edited the book in our personal time and it is our families that we need to thank for putting up with the time spent on this project. Our gratitude especially goes out to Louise and Nicola for this time.

We would also like to thank our colleagues and managers at VMware, who gave us both the opportunity and support throughout this great experience. A special note of thanks goes out to our editors and reviewers, most of all, Steve Bridle at VMware, who graciously agreed to technically review the book for us.

Finally, we would like to thank our customers and mentors who have given us the opportunity to improve the way their organizations manage a virtualized environment through the use of vRealize Operations Manager.
