In this chapter, you were introduced to the services that will be used throughout this book. You already know how to create new AWS users with restricted privileges, how to use the AWS CLI and the Node SDK, and what the frontend, backend, and notification services are. This chapter finished showing how each service fits in our sample application architecture and you learned how to estimate its costs.
In the next chapter, you'll be introduced to the Serverless Framework that plays an important role in our development workflow, automating tasks and organizing the code. You'll learn how to configure, deploy Lambda functions, and structure the beginning of our sample application.
