If you're an indie dev, and you're writing a backend for your game,

1st: don't write a game that needs a backend.

2nd: if you really must, write it in the same language as your client

3rd: don't write it in a way that requires deployment any more complex than

1. Install database/redis/w.e. and start those services

2. Copy a folder w/ your executable and config files to the server and running it

An artist should be able to run it on their laptop w/out fucking around too much
