TIL: K8s PodDisruptionBudget (PDB) can block node draining if minAvailable is set without maxUnavailable. Best practice: Use maxUnavailable=1 or 25% - it provides clear boundaries for pod eviction while maintaining availability 🔄 #Kubernetes

AWS Pro Tip: Implement mandatory resource tagging using AWS Organizations SCPs + Terraform aws_organizations_policy. Tag environment, owner, cost-center & project at minimum. Makes cost allocation reports actually useful and saves hours debugging cross-account bills.
