A few years ago, we had a classic case of a monolith. It had served us well, but as we grew, it was becoming a real bottleneck. Deployments were a pain, and a small bug in one part of the system could bring everything down. We knew we had to make a change.
So, we decided to move to a microservices architecture. It wasn’t an easy decision, and it took a lot of planning, but it was worth it. Here’s a quick look at why we did it and what we learned along the way.
The Problem with the Monolith
Our old system was a single, massive application. It was hard to make changes quickly, and our deployment process was slow and risky. We were also paying for more server power than we needed, just to be safe.
How Microservices Helped
By breaking our application into smaller, independent services, we were able to:
- Ship features faster: Teams could work on their own services without stepping on each other's toes. Our deployment times went from days to hours.
- Improve reliability: If one service had a problem, it didn't take down the entire system.
- Scale smarter: We could scale individual services based on their actual usage, which saved us a lot of money on our infrastructure costs.
It wasn't all easy, of course. We had to learn a lot about things like service discovery, distributed tracing, and how to manage a more complex system. But in the end, it was the right move for us. It’s made our whole engineering process more efficient and a lot less stressful.
