A proxyless approach lets a microservice send telemetry directly to the service-mesh control plane through gRPC, without attaching a sidecar proxy or changing application traffic flow to pass through one. section 4.2
The deployment model has these practical implications:
- The microservice communicates directly with the control plane rather than relying on an Envoy sidecar to observe inbound and outbound traffic. section 4.2
- Developers avoid implementing monitoring probes in application code while operations teams retain real-time visibility across the service mesh. section 4.6
- Proxyless deployment is one option alongside sidecar proxies and proxies running inside virtual machines. section 4.2
Use the proxyless architecture figure to compare direct service-to-control-plane telemetry with sidecar-based communication. section 4.2
