The author presents concrete concepts on how to increase the reliability of IT systems, drawing on many years of concrete experience in the development of highly available systems. Increasingly, mission critical business processes are IT-based. Redundancy can and should be implemented on different abstraction levels: from the hardware, the operating system and middleware components up to the backup computing center in case of a disaster. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, with all examples referring to UNIX and Linux Systems.
Rezensionen / Stimmen
From the reviews:
"The book's goal is to explain how to insure that IT services are available when needed, while keeping a good balance between their benefits and the cost to support them. . the book has as its target audience several groups: architects and system developers/designers for DR/BC/HA solution specifications . . The text is very clear, and includes 83 figures with detailed explanations, 26 tables, references, and a ten-page index. . All of these features make the book very practical and attractive."
