Chapter 6: Amazon DynamoDB

In this chapter, we are going to look at the first of the NoSQL databases that AWS offers, DynamoDB. DynamoDB is a major topic in the AWS Certified Database – Specialty exam, and for a large number of Database Administrators (DBAs) who have come from a relational database background, it can be one of the most difficult to understand given how differently it works to a SQL database.

This chapter will include hands-on labs where we will deploy, configure, and explore a DynamoDB table, and we will spend some time learning how to interact with a DynamoDB table using code. DynamoDB does not require a Virtual Private Cloud (VPC) to be deployed in.

In this chapter, we are going to cover the following main topics:
