There is no statute that says your work must live in their branded server farms. Think of how much money was spent on conferences, content, and marketing to make us believe their way is better. Fear is not a legislature.
The rule had a rhythm: real companies do not keep computers. Real companies rent. Real companies accept that the key to success is giving over your work product to strangers at soulless billion-dollar companies, because. Repeat that lie in enough hallways and a twenty-year-old who can build a whole product in a weekend will still apologize for running their own start-ups website on their own silicon.
Breaking the rule looks unglamorous. It looks like a quiet box in the cornder of your room. It looks like walking away from a campus that was never going to put your name on the glass. The people using SRV are the same people who learned the old cloud stack, noticed the invoice forever growing, and decided seriousness can live in a garage without asking permission.
Srv is not a manifesto nailed to a door. It's just a rebirth of common sense. Build as cheaply as possible and maximize your chances of success. If you need more horsepower, the big boys will still be there.
What you will be told
That you are going backward. That only a giant can be trusted with a door on the public web. That your smallness is a risk. Answer with the work: a site that stays up, mail that arrives, a second backup machine that takes over. Results win over slogans, and make your pitch deck look smarter.
