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
