Not every workload requires the same level of protection.
Some applications can tolerate a few hours of downtime, while others must remain available continuously.
The right disaster recovery model depends on business requirements, recovery objectives, budget, and application criticality.
| Business Requirement | Recommended Model |
|---|---|
| Lowest Cost | Backup & Restore |
| Cost Optimized Recovery | Pilot Light |
| Fast Recovery | Warm Standby |
| Enterprise Applications | Active Passive |
| Mission Critical Services | Active Active |
If downtime directly impacts revenue, customer experience, or regulatory compliance, organizations should consider Warm Standby, Active Passive, or Active Active architectures.
For development, testing, and non-critical applications, Backup & Restore or Pilot Light may be sufficient.
