In this chapter, you have learned a bit more about serverless functions architecture, how to build a notification service using the web framework Flask, and how to deploy the final application to AWS Lambda using the great project Zappa.
Then, you learned how to install, configure, and use the AWS CLI tool, and used it to upload files to an AWS S3 bucket.
We also learned how to integrate the web application that we developed in Chapter 7, Online Video Game Store with Django, and the order microservice that we developed in Chapter 8, Order Microservice, with the serverless notification application.
