AWS CloudFormation is an infrastructure as code (IaC) tool that allows you to declaratively define your cloud resources in textual templates. CloudFormation enables robust and easily repeatable deployments.

Custom resources in AWS CloudFormation enable you to provision infrastructure outside of AWS, such as third-party or organization-specific resources. By using custom resources, you can manage all of your resources in one place.

In this lab, you will implement an AWS Lambda that can be used to provision a non-AWS resource. And you will create an AWS CloudFormation stack containing a custom resource that is backed by the AWS Lambda function.
