A Not-so-Scary Way to Add Istio to Your Platform, Step by Step
summary
Stepwise recipe that actually installs Istio on Kubernetes: add the control plane, deploy an Ingress Gateway, create a small VirtualService to glue an existing K8s Service to that gateway, then add a secondary load balancer and a bypass virtual service plus a ServiceEntry to test traffic without touching production. Next enable sidecar injection to get mutual TLS, observability (Prometheus/Kiali) and authorization policies. Notes: extra hop adds latency, custom binary protocols may need port exclusions, ambient mode is not yet production-ready.
