So the lesson here is that for a first step into NoSQL, we went with a hosted solution so that we didn’t have to build a team of experts to run it, and we didn’t have to decide in advance how much scale we needed. Starting again from scratch today, I would probably go with DynamoDB. It’s a low “friction” and developer friendly solution.
You can look at this in two ways: 1) a biased opinion of someone that has already betted on Amazon with the infrastructure of a multi-billion business; 2) the opinion of someone that has accumulated a ton of experience in the NoSQL space and that is successfully1 running the infrastructure of a multi-billion business on NoSQL solutions. I’d strongly suggest you to think of it as the latter.
