Episode 50 — Plan Disaster Recovery End to End: Sites, Replication Distance, and Business Continuity
This episode teaches disaster recovery as an end-to-end plan that combines technology, process, and business priorities, which DS0-001 tests through scenarios involving regional outages, provider failures, and recovery objectives that force architectural decisions. You’ll learn how to design DR using site concepts such as cold, warm, and hot readiness, and how those choices affect cost, complexity, and achievable RTO. We’ll cover replication distance and failure domains, including why “different rack” is not DR, why different availability zones may still share dependencies, and how cross-region designs introduce latency and consistency considerations. Business continuity will be framed as ensuring critical functions continue, meaning you must consider application dependencies, identity services, DNS or traffic management, and operational staffing during extended incidents. Scenario examples will include selecting a DR strategy for a regulated workload with strict RPO, testing DR without impacting production, and identifying why a DR failover plan fails because secrets, certificates, or routing updates were not included in the runbook. By the end, you should be able to justify a DR design with clear links to objectives, failure scenarios, and testability, which is exactly the reasoning DS0-001 expects.
