What this book covers

This book provides practical guidance and readers will learn about the following:

• Serverless computing, the benefits it provides, and when to use it
• What serverless computing isn't
• Function as a Service (FaaS) and the different technologies that are provided by three public cloud providers: AWS Lambda, Azure Functions, and Google Cloud Functions
• Different triggers that you can apply to your serverless functions in AWS, Microsoft Azure, and Google Cloud Platform
• How to build serverless application across three public cloud providers using code samples
• How to use programming languages such as Node.js and code editors such as Visual Studio Code to set up your development environment to build serverless applications
• Best development practices with serverless computing to create scalable and practical solutions
