Server setup before the rewrite:

docker + php-fpm + php7 + larvel + nginx + redis + cron + worker + certbot

Server after the rewrite to Golang:

server, a 15MB no-dependencies binary that has everything.

Since I plan to use it for the rest of my life, I need the code and infrastructure to be radically simple and easy to maintain.

Like, I should be able to open it even after a few years, and do some fixes or add some features.

Go's ecosystem seems to share this mindset.
