Preface

Serverless computing allows you to build and run applications and services without thinking about servers. Serverless applications don't require you to provision, scale, and manage any servers. You can build them for nearly any type of application or backend service, and everything required to run and scale your application with high availability is handled for you. Building serverless applications means that your developers can focus on their core product instead of worrying about managing and operating servers or runtimes, either in the cloud or on premises. This reduced overhead lets developers reclaim time and energy that can be spent on developing great products that scale and are reliable.

This book teaches the basics of serverless computing and explains how to build event-driven apps using serverless frameworks on three public cloud platforms: AWS, Microsoft Azure, and Google Cloud. This hands-on guide dives into the basis of serverless architectures and how to build them using Node.js, Visual Studio Code for code editing, and Postman. This book teaches you how to quickly and securely develop applications without the hassle of configuring and maintaining infrastructure on three public cloud platforms.

You will learn how to harness serverless technology to rapidly reduce production time and minimize your costs, while still having the freedom to customize your code without hindering functionality. Upon completion of the book, you will have the knowledge and resources to build your own serverless application hosted in AWS, Microsoft Azure, or Google Cloud Platform, and will have experienced the benefits of event-driven technology for yourself. You will apply the fundamentals of serverless technology from the ground up, and will come away with a greater understanding of its power and how to make it work for you.
