Why traditional REST isn’t always enough and how gRPC is changing the way our microservices talk to each other.

If you are building microservices, mobile backends, or real-time data streams, you have probably hit a wall with traditional API communication. The web has grown, our systems have scaled, and the old ways of doing things are starting to show their limits.

Recently, I had the privilege of presenting a webinar to the Cloud Native Addis Ababa community about one of the most powerful technologies in modern backend development: gRPC. I wanted to adapt that session into a comprehensive article series because understanding gRPC is rapidly becoming an essential skill for any backend engineer.

Before we start looking at lines of code or complex architecture diagrams, we need to set the stage. At its core, modern backend development is entirely about communication.…
