That's a really good point and the foundation for what we're building with Graphcool (https://www.graph.cool). It's basically combining a GraphQL BaaS with AWS Lambda (or similar services). We take away the pain of configuring and maintaining your database + GraphQL schema so you can focus on implementing your business logic.
Our mission is to make software development like playing with Lego. You're combining existing services like Stripe, Algolia (...) to quickly build your own applications. GraphQL is the common denominator between all these components and provides an incredible developer experience.
On a more general note what distinguishes Graphcool from other services: We're optimizing for the best possible developer experience (DX) while maximizing the degrees of freedom what's possible to build with Graphcool.
