Welcome to Programming AWS Lambda. We’re glad you’re here!Serverless computing is a revolutionary way of building systems. At its heart, serverless is about performing the minimum technical work necessary to sustainably provide value to our users. A serverless approach does this by making the most of services provided by cloud vendors, like Amazon Web Services (AWS).In this book, you’ll learn how to architect, build, and operate serverless applications that use AWS Lambda—the original, and widely adopted, serverless compute platform. AWS Lambda is rarely used by itself, however, and so while reading this book, you’ll also learn how to successfully integrate Lambda with other serverless AWS services, like S3, DynamoDB, and more.
