When I was initially approached to write this book, the first and most obvious question was why should I do this? However, upon reflection, I thought of my personal experiences with the product and considered the real-world difference it made during times where we needed to troubleshoot performance problems or report on capacity trends. We also considered those customers with whom we had either demonstrated or run knowledge transfer sessions of vRealize Operations, and how only after a few hours, the energy in the room changed as people begin to grasp the power and concept of how vRealize Operations can benefit them on a daily basis.

The second reason is based on the observation that in some environments that had the product deployed, many of the concepts, terminology, and settings were not well-understood. As a result, customers were not getting the maximum value from their investment simply because they weren't familiar enough with the product. The product has extensive and great documentation; however, most product documentation is generally very thin on the why; such as, why should I enable some containers for capacity management and not others? Through this book, I attempt to fill this gap and hopefully show the positive impact this product can bring to an environment.
