Protocol Buffers (Protobuf)

A language-neutral, platform-neutral, extensible mechanism for serializing structured data. It is superior to JSON for high-performance, low-latency inter-service communication (especially when paired with gRPC). While simpler than full RPC frameworks, mastering its schema definition, versioning, and integration into a polyglot microservices environment is a specialized skill.
