How does Rails handle large-scale service mesh integration in microservices ecosystems?

Rails integrates with service meshes like Istio or Linkerd for traffic management, security, and observability.

A service mesh abstracts network communication between microservices. Rails services run inside a mesh where sidecar proxies handle retries, encryption (mTLS), routing, and observability. This removes networking complexity from Rails code and shifts it to infrastructure layer. It improves security and resilience in distributed systems.
