 There are two ways you can invoke this script (Python program). Either from a computer that has Python installed, or you could install it
 as a Lambda function. If you want to run it as a Lambda function, a CloudFormation template is included in the repo that will:
 - Create a role that will allow the Lambda function to:
-    - List AWS regions. So it can scan all regions for FSx for ONTAP file systems and volumes.

 can take a significant amount of "clock time" to run, especially in distant regions.
 
 Once you have installed the Lambda function it is recommended to set up a scheduled type EventBridge rule so the function will run on a regular basis.
