+The gRPC server and the HTTP gateway exposes the health endpoints for liveness and readiness probes in containerized environments and kubernetes. All the probes return whether all the servers are running or not. The health check works both on the gRPC server and the HTTP server and can be tested using the following commands:
+
+```bash
+# gRPC server
+$ grpc-client-cli health localhost:19090

+ "status":  "SERVING"
