I think its possible to skip the whole virtual service and ingressgateway part, isn't it? This would save up a lot of resources in our case

Would love to hear your thoughts

You can implement it without additional Istio resources, but the Istio sidecar requires a self-managed certificate. I have not explored that, Refer to the below repos for example without istio.

Thanks for your response - this could maybe be the solution: https://istio.io/latest/docs/tasks/traffic-management/ingress/ingress-sidecar-tls-termination ?

not sure if its possible to set the required env in gke anthos 🤔
