Описание: 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 Go serverless application and deploying it to Lambda.

This book starts with a quick introduction to the world of serverless architecture and its benefits, and then delves into AWS Lambda using 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. You will also learn how 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'll learn how to troubleshoot and monitor your apps in near real-time with services such as AWS CloudWatch and X-ray. This book will also teach you how to secure the access with AWS Cognito.

By the end of this book, you will have mastered designing, building, and deploying a Go serverless application.

Бессерверная архитектура популярна в техническом сообществе благодаря AWS Lambda. Go прост в освоении, прост в работе и легко читается другими разработчиками; и теперь он объявлен поддерживаемым языком для AWS Lambda. Эта книга — оптимальное руководство по разработке бессерверного приложения Go и его развертыванию в Lambda.

Эта книга начинается с краткого введения в мир бессерверной архитектуры и ее преимуществ, а затем углубляется в AWS Lambda на практических примерах. Затем вы узнаете, как спроектировать и создать готовое к работе приложение на Go с использованием бессерверных сервисов AWS без предварительных инвестиций в инфраструктуру. Книга поможет вам узнать, как масштабировать бессерверные приложения и работать с распределенными бессерверными системами в производственной среде. Вы также узнаете, как регистрировать и тестировать ваше приложение.

Попутно вы также узнаете, как настроить конвейер CI/CD для автоматизации процесса развертывания ваших функций Lambda. Кроме того, вы узнаете, как устранять неполадки и отслеживать свои приложения практически в реальном времени с помощью таких сервисов, как AWS CloudWatch и X-ray. Эта книга также научит вас, как защитить доступ с помощью AWS Cognito.

К концу этой книги вы освоите проектирование, создание и развертывание бессерверного приложения Go.
