Overview of this book

Serverless applications and architectures are gaining momentum and are increasingly being used by companies of all sizes. Serverless software takes care of many problems that developers face when running systems and servers, such as fault tolerance, centralized logging, horizontal scalability, and deployments. 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 finishing 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. This hands-on guide dives into the basis of serverless architectures and how to build them using Node.js as a programming language, Visual Studio Code for code editing, and Postman for quickly and securely developing applications without the hassle of configuring and maintaining infrastructure on three public cloud platforms.

Google Cloud Console

Before we start looking into the Google Cloud Functions Console, let's look at the process of getting a Google Cloud Platform account. Google Cloud Platform offers a 12 months' free trial and also gives you $300 credit to get started with Google Cloud Platform. If you spend $300 credit in the first 12 months, then you need to upgrade to a paid account in order to continue to use Google Cloud Platform services.

You can sign up for Google Cloud Platform using your Google Account at https://console.cloud.google.com/freetrial.

To be able to create a Google Cloud Platform account, you will need a Google account. Once you have created the Google Cloud Platform account, a new project needs to be created so that you can start building apps to run in the Google Cloud Platform environment:
