Istio Pilot is the microservice proxy mesh orchestrator. It is responsible for dynamically configuring proxies in a cluster platform environment to support L7-based routing, request destination policies (load balancing, circuit breaking), and point-to-point control policies such as fault injection, retries, and time-outs.
