A remote communication framework developed by Google that allows distributed services within an application to communicate efficiently and quickly. gRPC uses HTTP/2 as its transport protocol and Protocol Buffers (protobufs) as its data serialization format, optimizing the speed and efficiency of message transmission.
Features:
- RPC (Remote Procedure Call): gRPC follows the remote procedure call model, enabling clients to execute functions on remote servers as if they were local. This abstraction simplifies building distributed services, as it hides the complexity of communication between services.
- HTTP/2: Unlike HTTP/1.1, gRPC leverages HTTP/2, which supports features like multiplexing (multiple simultaneous calls over a single connection), header compression, flow control, and persistent connections. This enhances efficiency and performance, particularly in mobile or high-traffic networks.
- Protocol Buffers (protobufs): gRPC uses Protocol Buffers by default for data serialization, which is much more efficient and faster than formats like JSON or XML in terms of both size and speed.
