Editing One Quick Way To Host A WebApp (section)

== The Design ==

# I use Namecheap for domains ever since Google Domains went down
# I use Cloudflare for DNS ever since Google Domains went down
# I use Cloudflare as a web proxy
# I use Cloudflare R2 for persistent storage
# I use nginx as a reverse proxy
# I use certbot to get a Let's Encrypt SSL cert
# I run each app in Docker
# I keep them running using systemd
# I use a single MySQL and a single PostgreSQL on the same host
# I build my apps on the host

The idea is that nothing should lock me in too hard because I will likely not pay enough attention to it and the ecosystem will change around me and then I'll be stuck. Each bit here acts as middleware and is easily substitutable.

The rawest thing is the SQL DB and the app itself. We wrap that in Docker so environments are fixed. We wrap that in systemd so restarting is easy. We point nginx to that so that we can have a high-performance front-end serve static files and so on. We wrap that in Cloudflare so that we can get speed. And then we need DNS and a domain to get things done.

R2 for storage means we've got all the data somewhere nice and with it mounted locally we can just dump DB backups to it.

If each piece went away it would be straightforward to just disable it and move one step back. Nothing is catastrophic.
