Notes:

• Keep using your project name as the prefix for the resource names.
• Deploy the Queue, if you missed that at the beginning.
• Use the AWS UI to check that the SQS Queue is the source for the Lambda-Function.
• Send a message to the Queue and check that the function has been called.
• Use the follwing commands to check the event source of your function.

aws lambda list-functions
