Learn AWS Serverless Computing

The basics

Amazon DynamoDB is a fully managed serverless database service that you can use to provision tables, create indexes, and store data. It has extremely scalable performance and supports event-driven programming models. DynamoDB is often referred to as the petabyte storage database because its performance scales consistently and predictably, no matter how much data you load in. Like S3, writes to the database are replicated to three availability zones within a region, and you can specify in your queries whether you want a strongly or eventually consistent read operation.

One of the core premises of using DynamoDB is that you can focus on running your business instead of being distracted by having to feed and water your database.
