Question: Why is DynamoDB so expensive?

Answer

The cost of using DynamoDB depends on the capacity mode that you choose for your table and the amount of read and write throughput that you provision for your table. In general, DynamoDB is more expensive than other NoSQL database options available on the market, such as Apache Cassandra or MongoDB.

DynamoDB isn't meant to be expensive, but if you make a bad data model or perform Scans, you consume a lot of throughout and end up wracking up a massive bill.
