Using the AWS CLI to Create an AWS Lambda Function
This hands-on lab provides experience with creating and customizing Lambda functions, all from within the CLI. The primary focus will be on Lambda, AWS CLI, and CloudWatch log streams. AWS Lambda allows you to create functions and only have to worry about managing your code. Using the CLI allows you to "ditch the clicks" — all those mouse gestures required when you create a function within the console.
