What You'll Learn​

  • Istio multi-cluster architecture: Shared control plane vs replicated control plane
  • Subsecond failover mechanics: Active health checking, immediate rerouting, no DNS TTL delays
  • Operational complexity: Certificate management (mTLS), mesh upgrades, debugging service mesh config
  • Performance overhead: Sidecar proxy latency, CPU/memory per pod
  • When service mesh makes sense: Hot-hot with subsecond RTO requirements, complex traffic management needs
