Spreading Apps, Controlling Traffic & Managing Costs in Kubernetes
summary
Shows how to spread replicas with pod anti-affinity and topologySpreadConstraints to avoid single points of failure, then uses Istio destination rules and topology-aware hints to bias traffic to same AZ and reduce cross‑zone egress. Demonstrates Karpenter provisioning with Karpenter workload consolidation, three replicas across three AZs, a 20-request check proving destination rules route as expected, and estimates three t3.medium nodes at about $91.04/month.
