High-Availability Database Cluster Architecture Diagram #269553 (License: Personal Use)

The image depicts a high-availability database cluster architecture featuring two mirrored server nodes, each with a cylindrical database storage layer, stacked green processing units (likely application or query engines), and black I/O controllers. A dashed blue line connects corresponding components across nodes, indicating real-time data replication or heartbeat communication for failover resilience. The surrounding beige chassis and pin arrays suggest integration into a rack-mounted hardware environment.

Used on cloud infrastructure, database administration, or DevOps documentation pages to explain redundancy, disaster recovery, or distributed system design; matches user intent for learning or implementing HA/DR solutions.
