Why Simple is Winning Again.

If you work in backend engineering, you know the drill. For the last ten years, the answer to every scaling problem was "Microservices." The idea was seductive. Break your big, scary application into tiny, independent pieces. Each piece does one thing well. They talk to each other over the network. If the "Payments" service crashes, the "Browse" service keeps working. It sounded like the perfect architecture. We all wanted to be like Netflix. But recently, the industry woke up with a massive hangover. We realized that for many of us, microservices didn't solve our problems. They just replaced them with different, harder problems. Now, the pendulum is swinging back. Not to the bad old days, but to something smarter. The Old Enemy: The Spaghetti Monolith To understand why we left monoliths in the first place, we have to remember what they used to look like. Before microservices, we built what I call "Spaghetti Monoliths." This was one giant codebase where everything was tangled together.
