## 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
|
