Episode 54: Fault Tolerance, Redundancy, and High Availability

Downtime is not an option for mission-critical systems. In this episode, we dive into fault tolerance, redundancy, and high availability—design strategies that ensure continuity despite component failures or unexpected disruptions. You’ll learn the differences between active-active and active-passive configurations, the role of clustering, load balancing, failover mechanisms, and geographically distributed resources. We also cover the importance of regular testing and monitoring to validate these systems. Building resilient infrastructure is a core CISSP competency and a vital part of risk mitigation planning.
