Multi-Region Kubernetes Failover with ArgoCD and GitOps


Cloud outages happen. Designing systems that survive the complete loss of an entire AWS or Azure availability zone or region requires immutable GitOps infrastructure declarations and continuous traffic health probes.
- ArgoCD declarative state reconciliation ensures multi-cluster drift is corrected automatically in seconds.
- Global Server Load Balancing (GSLB) with DNS failover reroutes user traffic within 15 seconds of region health failure.
- Active-active distributed CockroachDB clusters survive region drops without transaction corruption.
