What Went Wrong in My Distributed Sensor System — And What It Taught Me

I'm a noob to distributed systems — and I learned that the hard way. Distributed architecture had always interested me, so I decided to refactor one of my projects into a microservice-based system despite having little practical experience. What followed was a series of failures that taught me more about distributed systems than any tutorial could. This article walks through the challenges I faced while setting up my distributed microservice system, how I solved them, and what they taught me about building resilient services. But first, let's give a very short explanation of what a distributed architecture is to begin with. What is a distributed architecture? A distributed architecture describes a system that is built with services deployed independently of each other that collaborate to function as a single application. Instead of relying on one large application running on a single machine, responsibilities are split across multiple services. This improves scalability, fault toleranc
