Example Concept: Multi-region architecture involves deploying applications and data across multiple cloud regions to enhance resilience and reduce latency. Key practices include using global load balancers to distribute traffic, employing data replication techniques like cross-region replication for databases, and implementing automated failover mechanisms to ensure continuity during regional outages. Additionally, leveraging infrastructure as code (IaC) for consistent deployment and the Well-Architected Framework for assessing architecture can optimize performance and security.
