Even ten years ago -- and it's only gotten better since then -- you could use java to managed hundreds of gigabytes of memory with thousands of threads, and it would sit there and just do it with uptimes of half a year or more, while taking an absolute beating.

It's really well-built tech, with a very nice distribution story: no docker mess, no scribbling all over the OS, etc. Once you install the jvm, you can just ship one file -- jars are just renamed zip files, so you can add all dependencies to just one file.

I used it for servers. I wish writing it were as nice as ruby or python, but java is really well built. If you haven't tried it, you should give it a whirl.
