Episode 28 — High Availability Principles — Regions, Zones, and Redundancy

This episode explores the architectural principles that support high availability in cloud environments. We explain the role of geographic regions and availability zones in minimizing downtime and data loss, as well as how redundancy strategies apply to compute, storage, and networking layers. Load balancing, failover systems, and replication are discussed as mechanisms to maintain service continuity during failures.We also highlight design considerations such as latency impacts, compliance requirements for data residency, and cost implications of multi-region deployments. This knowledge will help you answer exam questions that test your ability to balance availability with performance and budget constraints.
