High Availability and Disaster Recovery
Springer Berlin (Verlag)
978-3-642-06379-4 (ISBN)
Companies and other organizations depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based processes. Business continuity is the ability to do business under any circumstances and is an essential requirement modern companies are facing. High availability and disaster recovery are contributions of the IT to fulfill this requirement. And companies will be confronted with such demands to an even greater extent in the future, since their credit ratings will be lower without such precautions.
Both, high availability and disaster recovery, are realized by redundant systems. 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, 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.
Elementary Concepts.- Architecture.- System Design.- Hardware.- Operating Systems.- Databases and Middleware.- Applications.- Infrastructure.- Disaster Recovery.
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." (Mihail Sadeanu, ACM Computing Reviews, Vol. 49 (4), April, 2008)
