Model 5: Active-Active
Active-Active is the most resilient disaster recovery architecture available.
Both data centers actively serve production traffic at the same time. If one site becomes unavailable, traffic automatically continues through the remaining site. This architecture delivers the lowest downtime and lowest data loss but requires the highest investment.

CONTINUOUS BI-DIRECTIONAL CEPH MIRRORING OVER DARK FIBER
Advantages
- Near-zero downtime because both sites are handling live hits smoothly.
- Near-zero data loss through continuous, low-latency synchronous mirroring.
- Automatic workload continuity with no manual runbook intervention required.
- Highest business availability profile matching international structural standards.
Challenges
- Most expensive model because dual active environments consume full cloud power.
- Complex architecture design requiring precise network anycast matching.
- Demands advanced automated split-brain prevention algorithms.
Typical Recovery Targets
