Final Review, Hardening, and Best Practices

Introduction

Before promoting a platform to production, it must undergo rigorous hardening and review. This final lesson covers the critical steps required to ensure your platform is secure, reliable, and ready for enterprise workloads.

Security Auditing

Review all components for adherence to the principle of least privilege:

1. RBAC: Ensure Kubernetes ServiceAccounts only have the permissions they absolutely need.
2. Network Policies: Restrict east-west traffic within the cluster.
3. Secret Management: Verify that all secrets are encrypted at rest and in transit.

Day-2 Operations

Plan for the long-term maintenance of the platform:

1. Observability: Ensure all critical metrics, logs, and traces are being collected and alerted upon.
2. Disaster Recovery: Test backup and restore procedures for stateful components.
3. Upgrades: Establish a process for rolling updates of Kubernetes clusters and platform tooling.
