In which cases and in which services is it recommended to use gRPC?

gRPC is recommended for the following cases and services:

• Microservice architecture: for efficient interaction between services with low latency and support for streaming data.
• High-performance systems: gRPC uses the HTTP/2 protocol and a binary transfer format (Protocol Buffers), which ensures less network load and faster serialization.
• Resource-constrained systems: compact message format and efficient protocol suitable for mobile and embedded devices.
• Inter-language communication: gRPC supports many programming languages, simplifying the integration of heterogeneous components.

Examples of services:

• Internal APIs in large distributed systems.
• Implementation of real-time communications with support for bidirectional streams.
• Systems where strict typing and a contract between client and server are important.

Thus, gRPC is suitable for projects where performance, scalability, and a strict API contract are important.
