Beyond Redundancy: How Geographic Redundancy Can Improve Service Availability and Reliability of Computer-Based Systems

Hardcover, xxvi + 304 pages, NOT ex-library. Gentle handling wear, book is clean and bright with unmarked text, free of inscriptions and stamps, firmly bound. Issued without a dust jacket. -- This book examines how geographic redundancy can be used to increase the availability and reliability of critical computer‑based systems. It explains how distributing services and data across multiple sites ensures continuity during outages, faults, or disasters, reducing the risk of downtime in communications, financial, and industrial environments. The discussion covers architectural principles, redundancy models, fault‑tolerance strategies, and site diversity approaches, moving from high‑level design concepts to detailed engineering practice. Practical issues such as latency, replication, network design, and failover coordination are analyzed, with examples drawn from telecommunications, transaction systems, and large‑scale IT infrastructures. The work also addresses operational and economic considerations, including the trade‑offs between performance, risk mitigation, and cost. By integrating conceptual frameworks with applied case studies, the study provides both researchers and practitioners with a comprehensive guide to the deployment of geographically redundant systems in areas where constant service delivery is essential.…
