I am completely new to the realm of self hosting. I don’t know a single thing about how I can self host stuff. Regardless, I have the curiousity to learn it by myself but I don’t know where to start. I cannot find any sort of wiki or FAQ articles, nor do I have the ability to ask the forum for every single problem or doubt I encounter during the setup. Can someone direct me to a beginner friendly site that teaches all there is about self hosting and all the questions and misconceptions that come with it?
Additionally, is a self hosted server only accessible inside my home? What about accessing the services outside, like Bitwarden or Nextcloud apps that require syncing and availability of data wherever I am? If it is useless outside, there would be no point for me personally to self host in the first place since I am perfectly fine with using cloud services for now and the convenience that comes with it. Plus, no one else in my family cares about self hosting and I don’t wish to spend the effort to convince them to in vain, so setting up a server for convenience of everyone at home is also out of the question.
Wait, is an old laptop also good enough for setting up a home server? I thought you would require a completely separated and dedicated PC box like the ones you can see in studios or offices. That’s new to me!
Definitely look into laptop servers. They have the benefit of having a built-in screen, keyboard and battery in case power goes down. IMO, as a fellow newbie, it’s an easy way to dip your toes into hosting using existing/cheap resources
You can use any computer as a server, you just have to realise that low powered computers will be able to do less than something more powerful.
As you get into it more, you might find that you need better hardware, or more network ports etc., but most of us would probably be ok with a decent PC.
Anything with a CPU, RAM, a SSD/HDD and a network port can host something.
Even an old smartphone could do it.
Could it do it well? No. Can you do it? Certainly
It’s like with tools: You can use a drill to make holes or use it as a hammer. Is it a good hammer?
Even small SBC like raspberry pi can be a home server. SBC, laptop, SFF PC, office/gaming PC, server rack, …they are all options with different pros and cons. What hardare you need depends on your use case. Free or cheap hardware is best to start with IMO. You might find you dont even need an upgrade, and if you do, you will probably know what you need
