Or any shared hosting provider. It bugs me so much how every project seems to think I want to run a cloud instance to host it and bring in that maintenance burden. It's stupid. Give me shared any day for the small stuff.
Nothing is deeply cloud-specific in the core stack— Opportunities to go cloud agnostic are there, we just might have to do it via contribution, as we have a few important projects on the go with conflict with the time this would take. But it's open source, and it will happen :)
