How Geographic Redundancy Can Improve Service Availability andReliability of Computer-Based Systems
Enterprises make significant investments in geographicallyredundant systems to mitigate the very unlikely risk of a naturalor man-made disaster rendering their primary site inaccessible ordestroying it completely. While geographic redundancy has obviousbenefits for disaster recovery, it is far less obvious what benefitgeoredundancy offers for more common hardware, software, and humanfailures. Beyond Redundancy provides both a theoretical andpractical treatment of the feasible and likely benefits fromgeographic redundancy for both service availability and servicereliability.
The book is organized into three sections:
* Basics provides the necessary background on georedundancy andservice availability
* Modeling and Analysis of Redundancy gives the technical andmathematical details of service availability modeling ofgeoredundant configurations
* Recommendations offers specific recommendations on architecture,requirements, design, testing, and analysis of georedundantconfigurations
A complete georedundant case study is included to illustrate therecommendations. The book considers both georedundant systems andgeoredundant solutions. The text also provides a general discussionabout the capital expense/operating expense tradeoff that framessystem redundancy and georedundancy. These added features makeBeyond Redundancy an invaluable resource for network/systemplanners, IS/IT personnel, system architects, system engineers,developers, testers, and disaster recovery/business continuityconsultants and planners.
