Execution & Cutover Protocol
Standardized deployment framework governing system migrations, infrastructure rollouts, and operational transitions across all Aevum Zenth divisions. Zero-downtime targets with automated rollback safeguards.
Runbook Execution
Step-by-step validated checklists executed by assigned workstreams. Every action requires dual authorization and timestamped verification.
Zero-Downtime Migration
Blue-green deployment architecture with canary traffic routing. Legacy systems remain hot-standby until post-cutover validation completes.
Rollback Triggers
Automated threshold monitoring (latency, error rates, data consistency). Immediate reversion protocols if SLA breach exceeds 2%.
Command Center Operations
24/7 cross-functional war room during T-48 to T+72. Division leads, infrastructure ops, and security on standby for rapid escalation.
Cutover Timeline & Milestones
Final Validation & Freeze
Code freeze enforced. Final UAT sign-off from business stakeholders. Backup snapshots verified. Communication sent to all impacted teams.
Environment Synchronization
Database replicas synced. DNS TTL reduced to 60s. Load balancers configured for traffic shifting. Rollback scripts dry-run completed.
Execution & Traffic Cutover
Legacy services throttled. Canary deployment initiated (5% → 25% → 100%). Real-time telemetry monitored. Business validation gates executed.
Stability Verification
Core transactions verified. Error rates <0.5%. Performance benchmarks met. Stakeholder notification sent. Command center shifts to monitoring mode.
Decommission & Handoff
Legacy infrastructure scheduled for decommission. Knowledge base updated. Operations transferred to BAU support. Retrospective documented.
Risk & Contingency Matrix
| Risk Category | Likelihood | Impact | Mitigation Strategy | Owner |
|---|---|---|---|---|
| Data Inconsistency | Medium | High | Checksum validation & delta reconciliation before cutover. Automated rollback if drift >0.1% | Data Engineering Lead |
| Service Degradation | Low | High | Auto-scaling policies pre-provisioned. Circuit breakers enabled. Fallback to legacy routing | Infrastructure Ops |
| Integration Failure | Medium | Medium | Contract testing completed. API versioning enforced. Message queue dead-letter monitoring | Platform Architecture |
| Access/Permission Drift | Low | Medium | RBAC/IAM state snapshot pre-cutover. Automated policy sync verification post-deploy | Security Compliance |
