The guy is Turkey or France building an app on sandstorm has bigger challenges than worrying about how to manage infrastructure.

He needs to figure out how to create a viable business, and his first order concern is getting to P/M fit by rapidly iterating and delivering product (often making several changes a day).

If they create a viable business, they have enough leverage and margins (given SaaS has very favorable unit economics) to pay for a infra and a dude to manage it,
