Beyond Redundancy

Book Description

How Geographic Redundancy Can Improve Availability and Reliability of -Based Systems

Enterprises make significant investments in geographically redundant systems to mitigate the very unlikely risk of a natural or man-made disaster rendering their primary site inaccessible or destroying it completely. While geographic redundancy has obvious benefits for disaster recovery, it is far less obvious what benefit georedundancy offers for more common , software, and human failures. Beyond Redundancyprovides both a theoretical and practical treatment of the feasible and likely benefits from geographic redundancy for both service availability and service reliability.

The book is organized into three sections:

  • Basics provides the necessary background on georedundancy and service availability
  • and Analysis of Redundancy gives the technical and mathematical details of service availability of georedundant configurations
  • Recommendations offers specific recommendations on architecture, requirements, design, testing, and analysis of georedundant configurations

A complete georedundant case study is included to illustrate the recommendations. The book considers both georedundant systems and georedundant solutions. The text also provides a general discussion about the capital expense/operating expense tradeoff that frames system redundancy and georedundancy. These added features make Beyond Redundancy an invaluable resource for /system planners, IS/IT personnel, system architects, system engineers, developers, testers, and disaster recovery/ continuity consultants and planners.
