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.

Chapter 1. Understanding the Serverless Model

Serverless is a model where the developer doesn't need to worry about servers: configuring, maintaining, or updating is none of their business. Although it is not an entirely new concept, the services that are offered nowadays are much more powerful and enable a wider range of applications. If you want to build cost-effective and scalable solutions, you should dive deeper into this subject and understand how it works.

In this chapter, we will cover the following topics:

  • What is serverless?
  • The main goals of serverless
  • Pros and cons
  • Use cases

After this chapter, you will be ready to start our hands-on approach, building an online store demo application, one piece per chapter.
