gRPC, short for Google Remote Procedure Call, is a high-performance, open-source framework developed by Google. It enables the communication between different services and is designed to work across multiple programming languages. gRPC has gained popularity in recent years due to its efficiency and low latency, making it an ideal choice for connecting microservices in distributed systems.
One of the key features that sets gRPC apart from other frameworks is its use of Protocol Buffers (protobuf) as its interface definition language. This allows developers to define services and message types in a simple format, which are then compiled into client libraries for a range of different languages.
