Ask HN: Cheap VPS providers, how did you start?

Hi everyone,

I was wondering how do new cheap VPS providers start their business nowadays. It seems there are more and more new providers popping in this world everyday, and with super low prices.

What challenges are you facing ? Also, do some of you launched a business as a part-time job ? I'm currently employed in a company as a software engineer, and I'm wondering about the feasibility of launching such a business using outsource client support as well as outsource network administration (which, for a small business, can cost as low as $50/month for a few servers and few clients).

Thanks for your answers !
