High Availability

A must read book for all IT Tycoon Wannabe.

Another building block in the Enterprise Computing Series

You cannot judge a book by its cover in most cases. This book's cover, however, subtly provides clues about what's inside. The picture is a panoramic view of Hong Kong taken from Victoria Peak. It accurately portrays the book, which is a high-level view of a wide number of topics related to high availability. If you are expecting nuts-and-bolts technical information, then you are better off purchasing Blueprints for High Availability. If you want a "how to" book that blends a specific technical approach with processes you should look at Mission Critical Systems Management. However, if you want a book that provides a clear set of processes, takes a business case approach, and touches on most of the issues associated with high availability, then this book is what you are looking for.Like Hong Kong, where realities are in the eye and mind of the beholder, the book can be viewed as addressing either high availability or service level management. In fact, the book uses service level management as the driving force behind achieving high availability.Included in the panoramic view of high availability are the many issues and factors that need to be understood in order to achieve high availability. It starts out with reasons why high availability is important, and quickly segues into factors, such as total cost of ownership (the treatment is pretty close to what GartnerGroup has been peddling since the early 90s). It does cause one to get back to basics and consider that a high availability solution has a lot of hidden costs.The book goes through the process chain needed to develop a business case for high availability (one of the book's strong points, in my opinion), through implementation of the solution itself. If you are familiar with other books in this series you will recognize the pattern. Unlike the companion books, though, this one does not contain contradictions or have glaring gaps in the processes. The authors have thought this one through and have the writing skills to make it readable and understandable.The treatment of service level management is highlighted by a chapter on user availability. If you are in IT you should read and take to heart this section. User availability is a key component of aligning IT to business. The complex and myraid political issues in Hong Kong sometimes seem trite compared to the political issues that surround aligning these two factions. The authors, like seasoned China watchers, provide insights about how to understand the seemingly inscrutable players and sage advice on hot to achieve consensus among the two opposing factions. Another area that impressed me was the attention paid to facilities as a key component of high availability. Although this was a high level view, it can serve as a checklist of considerations as you are developing the business case for high availability. There was one missing fact that I wish the authors would have highlighted: compliance with fire and safety regulations an
