Example Concept: Multi-region architectures use active-active or active-passive configurations to distribute traffic and workloads across different regions. Active-active setups allow all regions to handle requests simultaneously, providing load balancing and failover. Active-passive configurations designate one region as primary, with others on standby, ready to take over in case of failure. Data replication strategies, such as using global databases or object storage with cross-region replication, ensure data consistency and availability. Implementing DNS-based load balancing and health checks helps route traffic efficiently and detect regional failures quickly.
