I'm a backend developer and would like to learn about what goes into managing your own infrastructure e.g. dedicated servers in a co-located datacenter.

Let's say I buy 10 servers on Hetzner, what are my next steps? How do I secure these servers (networking, access management), what to use for monitoring, how best to deploy software?

Any books or articles you can recommend? A checklist?

What additional topics come into play if it were 100 servers, what about 1000?

I am currently using self-hosted Jenkins for my solo projects. I am considering switching to something new. Anything you can recommend? The only real requirement is that it needs to be easy to self host, not be too complicated (solo dev so I want most of my focus to go to developing not figuring out the CI) and be resource efficient (I only have 1 server).

I am fairly happy with Jenkins but mostly because I am familiar with it. Only real downside is the resource usage when idle. And some plugins are not really maintained anymore.

What would you use to build a mostly CRUD backend today?

In my experience a lot of the jobs I get are to build backends that are mostly CRUD operations with a few endpoints that present 'aggregated' or filtered views of that data. Most of these apps will also need some mechanism to do background processing.

What is your preferred stack to build such a backend today? What tools and frameworks do you like and what have you changed your mind on and don't like anymore (after using it)?

Does your choice of tools change depending on if it is a commercial venture or a personal project?

Curious to hear what everyone is using these days.
