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.

S3 static website hosting

Now that our application has been created, let's deploy it to a remote server. Instead of maintaining a web server, such as Apache or Nginx in an EC2 instance, let's keep it serverless and use an S3 bucket with the S3 website-hosting feature enabled.

Setting up an S3 bucket

To get started, create an S3 bucket either from the AWS console or with the following AWS CLI command:

aws s3 mb s3://serverlessmovies.com

Next, build the web application for production mode:

ng build --prod

The --prod flag will generate an optimized version of the code and do additional build steps, such as JavaScript and CSS minification, dead code elimination, and bundling:

This will give you the dist/ directory with...
