Warning: very in depth wall of text that may or may not cause you to lose precious minutes. TLDR below.
Started off back then when I was a young kid who liked online/multiplayer games. I would join communities/forums, blogs, etc that were related to those games (like Runescape).
And then after some time, I was interested in making my own website/community that were related to those online games, so I taught myself on how to create websites.
And then I learned about Wordpress. At first, the free hosted Wordpress didn't really cater to what I wanted. I wanted a domain. I wanted more options to customize how my website looked like.
So I looked into running and hosting your own Wordpress installation. And then I've gotten to know of web hosting. At first, being the young kid I was, paid hosting wasn't an option. I had to look for free web hosting services.
So I tried out almost every single free web hosting service out there. Not because I wanted the best/fastest hosting I could get for my tiny little online game community/website, but because the concept of web hosting was very intriguing. It was fun. You were able to point just about any domain and sub-domain you have to that web hosting service and you could do all sorts of things from there on. When I didn't have the money to register my own TLD, I'd look for sites that offer free sub-domains. There were so many. I'd register a ton of those sub-domains and point them to whatever free web hosting service I'd have. I'd experiment with HTML, CSS, and PHP. There were an abundance of PHP scripts and content management systems that I was able to upload via FTP to my hosting service, and I'd do all sorts of stupid things with those content management systems. Creating silly websites, silly forums, and whatnot that I'd show to my friends. I was considered a "whizz kid". A computer geek. And boy, I did have a passion for web hosting back then.
But as the curious person I was, I wanted to learn more. I wanted to find out
how people offered web hosting services. I had this thought of wanting to offer my own free web hosting services to friends. I was also still into multiplayer games, whether it be those Flash games that you could play online (virtual worlds and whatnot) or those that you'd have to download. I also wanted to create my own "private server" of those multiplayer games.
So I did my research on how I could host my own private server for whatever multiplayer game I was playing, and I also did my research on how I could run my own web hosting service.
And I've gotten the same results, on how I could do that; Virtual private server. It all seemed very, very foreign to me. There was no control panel! What? Linux? Ubuntu? Command line? SSH?
So I read, and I read. What are the chances I could score myself a FREE VPS? Nil. So I thought, nevermind. I dug and dug more about virtual servers and I saw articles and videos teaching you on how to setup a virtual server on your own computer. It involved Virtualbox/VMWare, something I was familiar of at that time, thanks to the curious kid I was, wanting to learn how to install a Hackintosh on a virtual machine, because I didn't have 2 computers. So I downloaded Ubuntu server, installed it on Virtualbox, learned how to use command line interface, install a web server, and from there on-wards I installed various hosting control panels, and from there I figured out on how web hosting services were offered. Or at least, how they work.
I think I am going way too in depth into this and am slowly starting to write out a very boring story about my geek self from many years ago. So I will simplify it. I slowly managed to get my own free VPS from Host1Free, which had allowed me to learn SO much more. I went quite some time before getting my hands on a dedicated server and learning on how virtual servers were created on Linux
This goes to show how much you can learn on the internet for free. All those skills I've acquired and learned all by myself with the help of the Internet and the abundance of information it contains has helped me earn my own pocket money, too, by providing my services to people I know in real life. I don't think people will find my story interesting, because I think I've written a lot of unnecessary things and elaborated on too many things (it is a habit of my own, I've realized), instead of just writing a simple paragraph with the main points on how I've gotten into the hosting industry. Safe to say I have a passion for the hosting industry, and I continue to be involved in it in the future, whether it be in terms of having a career related to it, or just a hobby.
TLDR; Wanted to know how to create my own website, learnt about web hosting, wanted to learn how web hosting works, found out about virtual private servers, wanted to learn how virtual private servers worked, found out about servers.
EDIT: Damnit. I just realized this thread was looking for more of a "how you started your company" type answer, instead of a "how you found out about VPSs" type answer. Don't mind getting this deleted or moved, because I remembered there was a more relevant thread for my answer.
