Disaster Recovery Patterns Preview Outline

Resilience for AI and data platforms using northern + metro pairings and checkpoint aware replication.

1. RPO / RTO Tiers

  • Tier A: RPO 0 (stream), RTO < 5m
  • Tier B: RPO < 15m, RTO < 30m
  • Tier C: RPO 1h, RTO 4h

2. Region Pair Model

  • Northern compute + metro compliance hub
  • Latency budgets for control plane calls
  • Cold vs warm GPU standby economics

3. Checkpoint Strategy

  • Layered: model weights + optimizer + metadata
  • Delta compaction cadence
  • Integrity hashing & merkle anchor plan

4. Network & Backhaul

  • Dual diverse fiber + sat fail-safe
  • QoS shaping for replication bursts
  • Encrypted overlay segments

5. Drill & Validation

  • Quarterly failover simulation
  • Automated artifact validation scripts
  • Recovery runbook sign-off workflow

Full version will include topology diagrams, cost model examples and bilingual annex. Feedback welcome.
