summary

Argues that GitOps alone breaks at scale for Istio across tens or hundreds of clusters and that pairing GitOps with a controller/operator solves it by translating high-level intent CRDs into mesh APIs, automating deployment and drift control. Describes using multi-cluster GitOps plus a control plane/controller to auto-discover clusters via label selectors, and to push gateways, virtual services, WAF, rate limits and auth policies; reports this abstraction is built for large real deployments and works at scale.
