Overview

"Training, systems support, backup and maintenance account for nearly 80% of the total cost of today's enterprise applications -- and much of that money is spent trying to squeeze increased availability out of applications in spite of weak design and management processes. In High Availability: Design, Techniques and Processes, two leading IT experts bring together ""best practices"" for every people and process-related issue associated with maximizing application availability. The goal: to help enterprises dramatically improve the value of their strategic applications, without spending more money. Using extensive real-world examples and scenarios, the authors cover the entire application lifecycle. Learn how to design systems that will be easier to maintain; ensure that new systems will not increase in cost later due to problems you could have anticipated; and plan long-term availability strategies. Discover how to improve redundancy, increase standardization, simplify backups, and much more. These strategies and techniques are applicable to any IT professional, at any level, in any architecture, from traditional mainframes through client/server to leading-edge n-tier environments. For all IT professionals, including system architects, project managers, administrators, software developers and software engineers."
