Sidecar Proxy
Sidecar Proxy
Definition
A sidecar proxy is a container injected alongside each application container in a Kubernetes pod that intercepts all inbound and outbound network traffic. By processing traffic at the sidecar layer, service meshes can enforce mTLS, collect telemetry, apply rate limits, and perform traffic shaping without any application code changes.
Envoy is the most widely used sidecar proxy.
