Monolith to Microservices: What Worked, What Hurt, and What We’d Do Differently
A while ago, our team took on a big task: moving our monolith application to microservices. We thought it would be a smooth upgrade — better performance, faster development, easier scaling.
But we quickly learned that while microservices can help, they also come with new challenges. In this article, I’ll share what went well, what went wrong, and what we would change if we had to do it all over again
What Worked Well
1. Independent Deployments
After splitting services, we could finally deploy without waiting for the whole app to be tested.
