AWS Lambda Function URLs are dedicated HTTPS endpoints for Lambda functions. With Lambda function URLs, developers do not need to rely on an intermediary service like API Gateway to map Lambda functions to HTTPS calls.

Function URLs allow invoking a Lambda function directly and can be associated with the latest version or a specified alias. Function URLs also allow developers to configure cross-origin resource sharing (CORS) to define how different origins can access and invoke the Lambda function via the URL. Function URL endpoints are globally unique and can be configured in the AWS console along with the AWS CLI or API. 

In this lab, you will create a Lambda function URL for both a new and existing AWS Lambda function using the AWS console.
