Could you explain a little (or preferably, in detail) how Now works under the hood? Are you using Amazon ECS? Lambda? Custom solution? Where is the user code ultimately running and how do you scale it?

I'm really excited about GraphQL, particularly its type system and introspection capabilities. What do you see happening to GraphQL in the short/mid future? Any plans to extend the spec with new major features or is it mostly going to remain as it currently is? What tools, other than GraphiQL, you imagine can be built on top of it? Is there anything Facebook uses internally? Are there any new tools being developed?
