🛠 I Built My Own Protocol for Microservices! 🚀 In microservices, we usually rely on HTTPS for service-to-service (S2S) communication. But HTTPS isn’t always ideal for internal backend communication — it adds extra headers (like sequence number, acknowledgment number) and follows a SYN → SYN-ACK → ACK handshake. ⚙ This makes the request heavy and slower. To solve this, Google developed gRPC — a lightweight alternative that uses: ✅ HTTP/2 for efficient, multiplexed streams ✅ Protocol Buffers (Protobuf) for compact data serialization 🔥 To truly understand gRPC's purpose, I decided to build my own basic protocol for microservices from scratch using Node.js TCP sockets. myProtocol : https://github.com/Abhijit-Jha/myProtocol Sometimes, the best way to learn is to build it yourself. This experience gave me deeper insights into how services talk behind the scenes.
