DynamoDB

DynamoDB is a fully managed, NoSQL database with high availability by default and that can be configured to scale automatically. The only reason that it can't be considered as a serverless database is due to its' pricing model. You must pay for provisioned resources even if no one is using your application.

However, DynamoDB is a great database, with many useful features, and AWS offers a generous permanent free tier. It is being extensively used in many serverless projects because it is cheap, easy to use and offers predictable performance. In this book, we are going to use DynamoDB as our main database. If you browse this chapters' code files, you will see the data layer of the serverless store implemented with SimpleDB and DynamoDB, but DynamoDB will be the default and the database where we will discuss here what features needs to be implemented for the serverless store.
