Announcing gRPC Support in NGINX , gRPC support comes in with nginx 1.13.9, it seems to be able to handle gRPC stream like HTTP.
NGINX can already proxy gRPC TCP connections. With this new capability, you can terminate, inspect, and route gRPC method calls. You can use it to:
- Publish a gRPC service, and then use NGINX to apply HTTP/2 TLS encryption, rate limits, IP‑based access control lists, and logging. You can operate the service using encrypted HTTP/2 (h2c cleartext) or wrap TLS encryption and authentication around the service.
- Publish multiple gRPC services through a single endpoint, using NGINX to inspect and route calls to each internal service. You can even use the same endpoint for other HTTPS and HTTP/2 services, such as websites and REST‑based APIs.
- Load balance a cluster of gRPC services, using Round Robin, Least Connections, or other methods to distribute calls across the cluster. You can then scale your gRPC‑based service when you need additional capacity.
