More About This Textbook
Overview
The complete "how-to guide" for maximizing the availability of enterprise systems.
Training, support, backup, and maintenance account for nearly 80 percent 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, 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 investing a dime more than necessary.
Discover how to create systems that will be easier to maintain, anticipate and prevent problems, and define ongoing availability strategies that account for business change. Whatever your IT role, whatever your IT architecture, this book can help you deliver the breakthrough availability levels your organization needs right now.
A best practices guide tothe people and process issues associated with maximizing application availability. Focus is on how enterprises can design systems that are easier to maintain.
Editorial Reviews
Booknews
Piedad (president of an internet service company) and Hawkins (an IT management consultant) discuss the issues associated with maximizing application availability. They describe cost-efficient ways to improve the value of strategic applications, with special emphasis on reliability, recoverability, serviceability, and manageability. They also offer advice on planning service-level agreements, strategizing for multiple platforms, lowering administrative costs, and leveraging availability features built into the existing hardware and operating systems.

Introduction
Back when the mainframe ruled the world, information technology (IT) practitioners quickly learned the value of a well-managed system. They understood the value of managing problems, changes, and other issues confronting large, mission-critical computer systems running an organization's most sensitive business functions.
When the popularity of mainframes waned in favor of less costly midrange and PC systems, IT organizations were caught in the frenzy of developing and deploying new business applications with breakneck speed. Suddenly, more computing power was available to end users, who wanted to accomplish more with it than ever before. The corporate information system grew in scope, use, and importance, with no end in sight.
Now that the dust has settled somewhat, both the IT organization and the leaders of the business recognize that an unmanaged state-of-the-art computer system can be as bad as having none at all. Symptoms of this problem with unmanaged systems manifest themselves in ballooning IT costs, overworked and demoralized IT staff, and user dissatisfaction.
This book demonstrates how to deliver maximum system availability and manageability throughout a computer system's lifecycle, from design through implementation and maintenance. We review every key technique for simplifying the management and maintenance of computer systems - including redundancy, standardization, backups, and many more. We discuss practical means of implementing these techniques to make your current and future systems far less prone to outages.
We cover technical and management issues, since you cannot achieve long-term systemavailability and manageability solutions without addressing both. We have written this book to benefit everyone in the IT organization. Technical staff will find practical operational solutions that can be implemented immediately. IT management will gain a better perspective of the end-to-end and interrelated requirements of running an IT shop. And Chief Information Officers (CIOs) and other senior IT executives will find forward-looking strategies for enhancing the IT infrastructure and its contribution to the corporate bottom line.
You can manage systems better if you design them with high systems availability in mind. This book will show you how to address your system availability problems, from start to finish.
