gRPC
Also known as: gRPC / Google RPC / ジーアールピーシー
Google's open-source RPC framework. Using Protocol Buffers as the IDL and HTTP/2 as the transport, it delivers lower latency and higher throughput than REST, making it popular in microservices and edge inference servers.
Overview
gRPC uses strongly typed Protobuf service definitions to auto-generate client/server code in multiple languages. Its binary protocol is more bandwidth-efficient than JSON, and its streaming support is used in AI model inference servers.
NestJS Integration
NestJS natively supports the gRPC transport, allowing a single service to expose both REST and gRPC interfaces. NVIDIA's NIM inference microservices also use gRPC for model serving.
