Overview of this book

This book will equip you with the knowledge needed to build your own serverless apps by showing you how to set up different services while making your application scalable, highly available, and efficient. We begin by giving you an idea of what it means to go serverless, exploring the pros and cons of the serverless model and its use cases. Next, you will be introduced to the AWS services that will be used throughout the book, how to estimate costs, and how to set up and use the Serverless Framework. From here, you will start to build an entire serverless project of an online store, beginning with a React SPA frontend hosted on AWS followed by a serverless backend with API Gateway and Lambda functions. You will also learn to access data from a SimpleDB database, secure the application with authentication and authorization, and implement serverless notifications for browsers using AWS IoT. This book will describe how to monitor the performance, efficiency, and errors of your apps and conclude by teaching you how to test and deploy your applications.

Summary

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.
