Summary

We have learned that the DynamoDB service is a very powerful NoSQL solution that supports writing and reading data at very consistent performance rates. We have learned about the differences between NoSQL and SQL databases, and the data that is suitable for each database type. We have also discussed the data structure and learned about how to manage DynamoDB, as well as how to access the data within the DynamoDB service. One very nice feature of the service is the ability to address it via HTTP, with standard PUT, GET, UPDATE, and DELETE methods. In addition, we can use JSON and JMESpath scripting to support some transactions, atomicity, and some other features usually reserved for SQL databases. In the next chapter, we will look into one of the message brokering services offered in AWS such as Simple Queue Service (SQS).
