Preface

Serverless architecture is popular in the tech community due to AWS Lambda. Go is simple to learn, straightforward to work with, and easy to read for other developers, and now it's been heralded as a supported language for AWS Lambda. This book is your optimal guide to designing a serverless Go application and deploying it to Lambda.

This book starts with a quick introduction to the world of serverless architecture and its benefits, then delves into AWS Lambda through practical examples. You'll then learn how to design and build a production-ready application in Go using AWS serverless services with zero upfront infrastructure investment. The book will help you learn how to scale up serverless applications and handle distributed serverless systems in production. Then you will also learn to log and test your application.

Along the way, you'll also discover how to set up a CI/CD pipeline to automate the deployment process of your Lambda functions. Moreover, you will learn to troubleshoot and monitor your applications in near real time with services such as AWS CloudWatch and X-Ray. The book will also teach you how to scale up serverless applications and secure the access with AWS Cognito.

By the end of this book, you will have mastered designing, building, and deploying Go-based Lambda applications to production.
