So you think you can mesh? Scaling ING's service mesh
summary
ING scales a service mesh from 1 to ~10,000 running instances over 8 years, servicing 37 million customers and ~2,000 microservices and already handling about 180 million requests; core pieces are a API Marketplace that issues JWT subscriptions and endpoint-level discovery, a control plane feeding a data plane with observability and client-side load balancing, automated certificate issuance for Mutual TLS, a Spring Boot library plus an in-house sidecar, an insides dump for runtime telemetry, and a regression suite that validates behavior during sidecar replacement.
