Web Apps
I used Django to build the billmaker invoicing site. Serving with apache2 was a pain. I had to make sure I installed the python3 version of mod_wsgi.
I have one Digital Ocean Droplet to host a couple of websites coming in from different domains.
HTTPS
I use Cloudflare to set up easy HTTPS connections to my domains. CloudFlare doesn't forward all the ports so I had to change one of my other sites to another port that Cloudflare accepts 1).
