    Edge Security Acceleration:gRPC

    Last Updated:Sep 19, 2024

    gRPC is an open source high performance Remote Procedure Call (RPC) framework that is developed based on HTTP/2. Using the protocol buffers (Protobuf) messaging format to serialize structured data, gRPC can connect services across languages and platforms and allows you to request a service from a remote server the same way you request an on-premises application. gRPC can also help users reduce bandwidth usage and network latency.

    Benefits of gRPC

    • Efficient communication: gRPC can concurrently process multiple requests over a single TCP connection by using the multiplexing feature of HTTP/2. This improves communication efficiency and performance.

    • Cross-language interoperability: gRPC supports multiple mainstream programming languages and allows the server and the client to use different languages for development. This facilitates the construction of heterogeneous systems.

    • Strongly typed interface definition: gRPC provides strict type checks and uses Protobuf to define your service interface and message structure. This helps reduce errors and simplify version management.

    • Stream processing: gRPC supports single-directional and bi-directional streaming RPC and is an ideal choice for big data stream and real-time messaging scenarios.

    • High security: gRPC can be integrated with Transport Layer Security (TLS) to support multiple identity verification and authorization mechanisms for communication security.

    Prerequisites

    • The SSL/TLS feature is enabled and the certificate is correctly configured for the site. For more information, see Configure edge certificates.

    • TLS, HTTP/2, and gRPC are supported by the origin server, and Match Client or HTTPS is specified for the Origin Protocol parameter. For more information, see Origin protocols.

    • application/grpc is used as the Content-Type header of gRPC requests.

    Procedure
