The admin of tech.lgbt is working on a collection of resources. You might find something useful in this thread: https://tech.lgbt/@david/103986050103236381

Darius Kazemi's https://runyourown.social/ is a useful resource, especially toward some of the more non-technical (and thus social) aspects.

I wouldn't go with AWS or anything that advanced for just running a Mastodon server.

I personally like Vultr for VPS's, DigitalOcean is okay too.

If you want managed Mastodon hosting, I can vouch for https://masto.host/ - it's really good, have rarely had issues, and if ever I did, the support is amazing.

Unless you're trying to get AWS experience with a side project you'll actually use, in which case it's worth looking into -- people have gone whole hog and set things up to use a managed DB and everything.
