This white paper from Fairwinds outlines best practices for managing Kubernetes at scale across four key pillars: security, cost optimization, reliability, and policy enforcement. It emphasizes secure configurations (RBAC, network policies, secrets management), right-sizing resources using tools like Goldilocks, and enhancing reliability through autoscaling, HA architecture, and liveness probes. It also recommends using Infrastructure as Code (IaC) and automated policy enforcement to ensure consistency across multi-tenant, multi-cluster environments. Tools like Polaris and managed Kubernetes services help enforce governance, reduce risk, and improve operational efficiency.
