Distributed databases will always require some kind of specialist knowledge to maintain. The physical deployment of code is actually the easiest part, the big problem is how to keep things running and fix issues once things invariably start breaking. The value proposition for hosted services is "we'll take care of everything, you don't have to worry about operations" while the value proposition for the development companies is "we'll help you run things and we'll reinvest the proceeds in maintaining the platform." The incentive for AWS is to extract maximum profit from open source projects (with no real regards for sustainability), while the incentive for the development companies are more aligned with having a sustainable long term community and product.
