Book description
How Geographic Redundancy Can Improve Service Availability and
Reliability of Computer-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 hardware, software, and human failures.
Beyond Redundancy provides 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
-
Modeling and Analysis of Redundancy gives the technical and
mathematical details of service availability modeling 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 network/system
planners, IS/IT personnel, system architects, system engineers,
developers, testers, and disaster recovery/business continuity
consultants and planners.
