Google Protocol Buffers (gRPC)

Google Protocol Buffers (commonly known as Protocol Buffers or protobuf) are a way for different computer systems to efficiently exchange structured data. Think of it as a compact, language-neutral format for encoding messages, enabling applications written in various programming languages to communicate seamlessly. gRPC is a framework built on top of Protocol Buffers that facilitates quick, reliable, and scalable remote procedure calls (RPCs), allowing one system to invoke functions or access data on another system as if it were local. Together, they enable fast, efficient, and cross-platform communication in distributed systems and microservices.
