Hands-On Serverless Applications with Go

By: Mohamed Labouardy

Overview of this book

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.

Securing Your Serverless Application

AWS Lambda is the ultimate pay-as-you-go cloud computing service. Customers just need to upload their Lambda function code to the cloud and it will be up and running with no underlying infrastructure to secure or patch. However, according to AWS's Shared Responsibility model, you're still responsible for securing your Lambda function's code. This chapter is dedicated to the best practices and recommendations one can follow in AWS Lambda to make applications resilient and secure according to the AWS Well-Architected Framework. We will cover the following topics in this chapter:

  • Authentication and user control access
  • Encrypted environment variables
  • Logging AWS Lambda API calls with CloudTrail
  • Vulnerability scanning for your dependencies
