Go Serverless! Stop worrying about infrastructure and ship more

Do you want to spend more time solving problems and less time fighting infrastructure? Have you heard of serverless but don’t know where to start? This workshop is for you!

In this workshop, you will learn by:
• using Go and the AWS Serverless Application Model (SAM) to create a simple web service using AWS Lambda functions
• testing and debugging your web service locally with SAM
• monitoring and troubleshooting your web service with distributed tracing using AWS X-Ray

After this workshop, you will be able to create your own web services with Go that scale automatically without having to manage any infrastructure.

To get the most benefit from this workshop, you should have Go version 1.11 or later and Docker Community Edition installed. You should already have an introductory level knowledge of the Go language and its build tools, but no prior experience with AWS is required.
