Summary
In this chapter, you invested in rearchitecting your previous application, and it is now more robust and feature-rich. Moreover, you focused only on serverless technologies such as Amazon API Gateway for our API, Amazon Cognito for the authentication layer, and Amazon Lambda for compute, and it should be clear how these technologies offer advantages in terms of scalability, cost efficiency, and operational effort. For the unchanged components such as Amazon S3 and Amazon CloudFront for the frontend, or Amazon DynamoDB as the data layer, you were able to practice and review it, so you should be more proficient with them.
In the next chapter, you will explore machine learning using AWS technologies to develop an image analyzer.
