Building Serverless Web Applications

By: Diego Zanon

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.

Preface

Chapter 6. Developing the Backend

Developing the backend without servers is the main drive of the serverless concept and what makes it so interesting. In this model, a paradigm shift is to break the project into small pieces of logic that can be deployed separately instead of one single bloated application. How to architecture this separation is covered in this chapter. Also, we will continue the development of our serverless online store building the backend using the following REST principles.

In a nutshell, we will cover the following topics:

  • An overview of serverless architectures
  • Organizing the project's code
  • How to create RESTful services

After this chapter, you'll have built the backend of our serverless online store.
