High Availability and Disaster Recovery

Companies depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, and all given examples refer to UNIX and Linux Systems.

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.

Thorough presentation of all technologically relevant aspects concerning high availability and disaster recovery Author regards all levels of abstraction and presents concrete concepts on how to increase the reliability of your IT Based on many years of concrete experience in the development of highly available IT systems Includes supplementary material: sn.pub/extras
