Distribution
Amazon CloudFront supports gRPC, an open-source remote procedure call (RPC) framework built on HTTP/2. gRPC offers bi-directional streaming and binary protocol that buffers payloads, making it suitable for applications that require low latency communications. To enable your distribution to handle gRPC requests, you must include HTTP/2 as one of the supported `HTTP` versions and allow `HTTP` methods, including `POST`. For more information, see Using gRPC with CloudFront distributions in the Amazon CloudFront Developer Guide.
