Triggering a Lambda Function in Response to a CloudTrail Log Event

In this lab, we are going to go over the process for triggering a Lambda function in response to a CloudTrail event. We will be using a variety of services, including CloudTrail, S3, Lambda, and SES to accomplish our goal of being notified via email when changes are made within the console. This is important for tracking changes that are made within your AWS account.
