A cluster is a starting point
A healthy control plane does not mean an application is ready for production. Readiness depends on workload identity, ingress, network boundaries, resource requests, disruption budgets and a documented operating model. Review these together rather than treating cluster provisioning as the finish line.
Define ownership and boundaries
Document which team owns the cluster, the application and each operational dependency. Use namespaces, RBAC and network policies to express those boundaries. Prefer workload identity over long-lived credentials, and verify that service accounts cannot reach resources outside their intended scope.
Make desired state reviewable
Store workload and infrastructure configuration in version control. Use GitOps reconciliation to make differences visible and reversible. Promote immutable artifacts between environments and test rollback behavior before relying on it during an incident.
Instrument the user journey
Collect metrics, logs and traces around application behavior, not just node health. Define service-level indicators from user-facing operations and make alerts actionable. Every alert should have an owner and a response path.
Exercise recovery
Backups are not evidence of recoverability until they have been restored. Test data restoration, workload rescheduling and dependency failures against agreed recovery objectives. Keep the runbook alongside the platform code and revisit it after material architecture changes.
