Example Concept: A resilient multi-region architecture typically includes active-active or active-passive configurations, where services are deployed across multiple regions to handle failover seamlessly. Data replication is crucial, using services like Amazon RDS Multi-AZ or Google Cloud Spanner for database redundancy. Load balancers and DNS services, such as AWS Route 53 or Azure Traffic Manager, direct traffic to the healthiest endpoints. Implementing Infrastructure as Code (IaC) ensures consistent deployment across regions, while monitoring and observability tools provide insights into system health and performance.
