  As the author of our internal pricing simulators, I can tell you we strive to be cheaper than Amazon DynamoDB for most workloads, while offering capabilities more like Google Spanner. If the price for our managed cloud isn't working for a customer, FaunaDB also runs great anyplace you can run a JVM, so there is the option to scale workloads on machines of your choice.

    DynamoDB on Amazon, not even counting the generous free tier, costs $0.09 per 5.2 million reads (queries I assume). https://aws.amazon.com/dynamodb/pricing/ https://aws.amazon.com/dynamodb/pricing/ The free tier is 200 million reads per month. That would cost $2M on your service.

      With Fauna you pay for operations, with Dynamo you pay for availability. So the worst case Dynamo pricing is when you must buy significantly more availability than actual operations. This is common with bursty workloads. The closer your workload is to steady state, the better off you are buying capacity, the more bursty you are, the better off you are buying operations. I don't have my calculator handy but if your use case is "adequate performance for my interactive app" Fauna ought to come out a little cheaper than DynamoDB. An app that's doing million of reads a month will see peaks closer to 100x that. That is the number that matters when it comes to buying capacity. 200 million reads a month works out to about 77 requests per second. If your app bursts to 77 requests a second, that's also within the Fauna Cloud free plan.
