gRPC: The High-Speed Backbone of Modern APIs

In this episode of Bits and Specs, we explore gRPC — Google’s high-performance, open-source RPC framework that’s powering everything from microservices to AI pipelines. We break down how gRPC works using Protocol Buffers, IDLs, and HTTP/2, and explain why it’s faster, leaner, and smarter than traditional REST APIs. With real-world examples from cloud systems, streaming platforms, and agent backends, this episode unpacks why gRPC is becoming the protocol of choice for developers building distributed, language-agnostic systems. Whether you're designing LLM infrastructure or just tired of JSON, this is the protocol you should know.
