Now that we have a basic API Gateway endpoint and Lambda function, the next meaningful step is to save the data posted to the API. Keeping with the AWS serverless theme, in this article we will add persistence with the help of DynamoDB. We will also keep things automated by continuing to utilize the AWS Serverless Application Model (SAM).

If you look closely, yes, there are certainly servers running our serverless applications in the cloud. However, the serverless approach and the platforms that enable it provide impressive capabilities without requiring us to manage the server environment. In this post I will begin developing a basic REST API with a serverless approach on AWS, starting with Lambda and API Gateway.
