Creating a Lambda Function Using the AWS Console
In this hands-on lab, you'll write a Node.js Lambda function that checks a URL (e.g. _www.amazon.com_) and returns the status code that signifies if the website is up and running or down. During this lab, you'll have the opportunity to explore the Lambda console, function code, execution roles, test events, and execution results. AWS Lambda allows you to write concise functions and only worry about your code. Since Lambda is serverless, AWS manages the underlying infrastructure for you.
