Example Concept: A resilient multi-region architecture typically employs active-active or active-passive configurations, where workloads are distributed across multiple regions to ensure availability. Active-active setups allow traffic to be served from any region, balancing load and providing redundancy. Active-passive configurations keep a secondary region on standby, ready to take over in case of a primary region failure. Critical components include global load balancers, cross-region replication for data consistency, and automated failover mechanisms. Implementing these strategies aligns with the Well-Architected Framework's reliability pillar, ensuring that systems can recover from failures and continue to function.
