Well, here's my first post on the fediverse!

Background in IT and server administration here. I however do not know much about the intricacies of the fediverse, but am interested in learning. Here's my two cents based on a background of LAMP stacks for web hosting.

The required space would likely scale and vary greatly depending on how much content is hosted locally. Assuming minimum space similar to a basic LAMP server it'd likely have starting space requirements of less than 1GB. If local content is primarily text/links to content hosted elsewhere it would take a lot to drastically change that space requirement. Image hosting can vary greatly depending on size, quality, and number of images. Video hosting is an absolute space hog even at fairly low resolutions by today's standards.

Bandwidth requirements would scale similar to storage requirements.

Other specs would also start very low if fediverse requirements are similar to a LAMP stack. Cores are typically more important than core speed in web server hosting as each request will try to use a separate core, but doesn't need much processing power to provide that request since the server isn't actually rendering anything.

Likewise, you shouldn't need much memory on a web host. Will scale with the number of scripts running on the host but I suspect that shouldn't be many unless you're also running moderation bots, but those should ideally be run on a different server instance.

That said, I'd also be curious to hear from other people that have experience with the fediverse though and other recommended specs to potentially host an instance.

If anyone has other questions I'm happy to try to help :)
