Building Mission-Critical Multi-Region Resilience: Hands-On with AWS Application Recovery Controller

When minutes of downtime cost millions in revenue and customer trust, traditional disaster recovery isn't enough. This session reveals how to architect, build, and operate highly resilient workloads using AWS Application Recovery Controller (ARC) for automated region switch orchestration—moving beyond theoretical RPO/RTO targets to proven patterns that deliver sub-minute recovery at scale.

You'll learn how to implement readiness checks that continuously validate your failover capability, routing controls that shift traffic between regions in under 30 seconds, and orchestration patterns that coordinate complex multi-service failovers without manual runbooks. We'll cover the critical architectural decisions that separate pilot light from active-active deployments, strategies to minimize data loss during
unplanned failovers when async replication creates exposure, and the operational discipline required to test failover regularly without impacting production traffic.

Drawing from real-world financial services implementations processing billions in daily transaction volume, we'll walk through actionable blueprints for multi-region Aurora Global Database deployments, DynamoDB Global Tables strategies, and event-driven architectures that maintain consistency across regions. You'll see live demonstrations of ARC routing controls in action, readiness check configurations, and automated
failover orchestration—plus the monitoring and observability patterns that give you confidence your systems will survive regional outages.

What You'll Learn:
- Multi-region architecture patterns: pilot light, warm standby, and active-active trade-offs
- ARC routing controls and readiness checks for automated failover orchestration
- Data replication strategies with Aurora Global Database and DynamoDB Global Tables
