Relational Database High Availability and Replication Diagram

This diagram shows how primary-replica setups, failover controllers, and backups combine to keep a relational database resilient. It's essential when planning database architectures that must minimize downtime. Tip: distinguish synchronous versus asynchronous replication links visually since their failover guarantees differ.

The prompt behind this diagram

Design a relational database high availability and replication architecture diagram. Show a primary database node handling writes, replicating synchronously to a standby node in the same availability zone and asynchronously to a read replica in a different region. Include a load balancer directing read traffic to replicas, an automatic failover controller monitoring node health, and a backup service performing scheduled snapshots to object storage.
