Few industries have grown as rapidly or as widely as that of information technology (IT). What began as an infant offshoot of the accounting profession a mere 40 years ago has since matured into a prevalent and compelling force in nearly every segment of business, industry, and society in general. IT is the latest, and most significant, of cultural revolutions.
Futurist author Alvin Tofler, in his book on cultural phenomena, The Third Wave, describes three significant movements in American social development. These were the agricultural revolution of the late 1800’s, the industrial revolution of the early 1900’s, and the information revolution of the last two decades of the twentieth century.
Some 30 years ago Tofler correctly forecast many today’s social and technological trends. But even he could not predict the rapid rate of progress that the IT industry would sustain, nor its profound impact on living standards and business practices.
Much has been written about various IT breakthroughs involving chip technology, compiler designs, hardware components, and programming languages. But little has been written about how to manage effectively the environment in which IT entities co-exist and thrive. This environment is commonly called the IT infrastructure. The process of managing the many attributes that contribute to a stable, responsive IT infrastructure is known as systems management.
This book offers a historical perspective of the various disciplines of system management, along with an in-depth technical treatment of each of them. The historical background explains the when and why of each discipline to enable a better understanding of its purpose and evolution. The technical treatment or process discussion of each discipline shows how to implement and manage each one effectively, regardless of the size or type of platform. For the first time, this book addresses systems management as it applies to mainframe data centers, midrange shops, client-server environments, and web-enabled systems alike.
The 12 disciplines of system management are presented in the approximate order in which they became prevalent and integral to an infrastructure’s operation. Obviously this prioritization will vary slightly from enterprise to enterprise, depending on the emphasis of applications running at a particular center.
