I used to be on the java hate train, but honestly the JVM is magic for infra. I worked at AWS, and I groaned so hard when I started. Then, I came to appreciate it because of the tooling and the types of issues that actually cropped up.
the nice thing about Java is you get pretty good performance even while pretending the hardware concerns don't exist. This takes a lot of things to think about off your brain. The downside is you can't choose to think about them even if you want to.
