A basic cluster installation supports a team working together to develop or test applications. To minimize work disruption, this landscape design includes a minimal high availability and disaster recovery infrastructure.
High Availability and Disaster Recovery Parameters
- Downtime: 4 – 24 hours
- Data Loss: 15 minutes – 24 hours
Typical Use Cases
- Enterprise productivity tools
- QA, prototype, proof-of-concept, or pilot environments
- Shared or complex development environments
- Deprecated, offline business applications that are retained for historical purposes
Minimum Landscape Design
- Clustered environment
- On-demand offline full backup, based on RPO target
- No disaster recovery environment
- Manual recovery process
Enhanced Landscape Design
- Clustered environment
- Redundancy in all tiers; no single point of failure
- Offline full backup (ad hoc)
- Online incremental backup
- Database snapshots
- Manual recovery process
Installation Scenarios to Implement
- Simple Load-Balancing Cluster, installed as both production and recovery systems
