Just chipping in with thoughts on DynamoDB, (although I have worked on much smaller scale systems) I am a long term dev, done lots of SQL, but for the past few years I have been using DynamoDB, and I am using it for my new startup (So I rate it). Cons - You have to be very aware of your query patterns, and not having ad-hoc queries is a pain. Plus sides - With on demand billing, its free if you aren't using it - Built correctly, it will scale - No Schema upgrades (This one is massive for me) On the last point, I really do appreciate not having to worry about keeping schemas upto date across all devs and environments. We use quite a simple pattern of a table per entity, as opposed to single table design, because it allows us to just use the API at the highest level of abstraction, where you just write your objects to dynamoDB. (You can still do lower level requests to poke values and such like)
