+## Stretched Cluster
+
+A cluster architecture that spans multiple availability zones, providing high availability and disaster recovery capabilities across geographic locations.
+
+## Definition
+In the context of VMware Cloud on AWS, a stretched cluster extends across availability zones (AZs) to provide increased resilience. If one AZ experiences failure, workloads can continue running in the other AZ.
+
+## Key Characteristics
+- **Cross-AZ Deployment**: Cluster nodes distributed across multiple availability zones
+- **High Availability**: Automatic failover if one AZ becomes unavailable
+- **Disaster Recovery**: Built-in DR capability without additional configuration
+- **Low Latency**: AWS AZs are designed for low latency interconnectivity
+
+## Use Cases
+- Mission-critical applications requiring high availability
+- Disaster recovery planning
+- Compliance requirements for geographic redundancy
+- Applications with strict RTO/RPO requirements
