One year after switching from Java to Go

The real win for this team isn’t just switching from Java to Go. It’s breaking free from the heavyweight framework ecosystem that the JVM all but forces on you.

It’s not that the JVM is bad or that Go is a silver bullet, but Go does act as a forcing function, pushing teams to write simpler, more efficient code without layers of boilerplate, indirection, and unnecessary IO.

You can still do inversion of control without an IoC container—instantiation works just fine! Look at Go’s HTTP middleware pattern with structural typing and first-class functions. No config files, no annotation magic, just composition, testability, and code small enough to hold in your head.
