Breaking the Availability Barrier: Volume III

Active/Active Systems in Practice

Photo of Breaking the Availability Barrier Volume III book coverVolume II extends the theoretical topics covered in Volume I and covers significant issues and technologies related to active/active architectures, including availability calculations, redundant reliable networks, distributed databases, total cost of ownership, and node failures. Volume III is a companion to Volume II and contains practical examples and case studies for actually building active/active systems based upon the principles covered in Volumes I and II.

About Volumes II and III

If you could configure your current system to:

We think so, and that is what this book is all about. Active/active systems can and do provide these benefits.

An active/active system is a network of independent processing nodes cooperating in a common application. If a node fails, then just switch over that node’s users to a surviving node. Recovery is in subseconds to seconds.

You will learn about actual successful installations of active/active systems. This book is for the IT executives who must reduce the downtime of their systems, for the system architects who are charged with significantly improving the availability of their systems, and for the operations staff who must manage and operate those systems.

About the Authors

The authors of the book, Dr. Bill Highleyman, Paul J. Holenstein, and Dr. Bruce Holenstein, have a combined experience of over 90 years in the implementation of fault-tolerant, highly available computing systems. This experience ranges from the early days of custom redundant systems to today’s fault-tolerant offerings from HPE (NonStop) and Stratus. Learn more about the authors.
