Istio Service Mesh Simplified Beyond a Single Cluster
summary
Istio now unifies the replicated and shared control‑plane models so operators choose primary vs remote control planes or even external control planes by region, and connect clusters with east‑west gateway pairs and generated create remote secret files for endpoint discovery. Demo builds a single mesh across four clusters (IBM Cloud + GCP) running Bookinfo with reviews v1/v2/v3 and succeeds—traffic routes and mTLS work across clouds. VM expansion adds experimental workload group and automated bootstrap plus a dns proxy, auto‑registration and health checks to simplify VM onboarding.
