Which service would you use to automate and manage the lifecycle of EBS snapshots?

Amazon Data Lifecycle Manager is the correct service to automate and manage the lifecycle of Amazon Elastic Block Store (EBS) snapshots. This service allows users to define lifecycle policies for EBS snapshots, making it easier to automate the creation and deletion of these snapshots based on specific schedules and retention policies.

Data Lifecycle Manager helps enhance data management in AWS by automating tasks that would otherwise require manual intervention, thus improving operational efficiency. For example, you can create policies to automatically back up EBS volumes at regular intervals, ensuring that data is consistently protected. Similarly, it allows for the automatic deletion of older snapshots that are no longer needed, helping to manage storage costs effectively.

In contrast, AWS Data Pipeline is primarily focused on the movement and transformation of data, rather than managing EBS snapshots specifically. AWS CloudTrail provides logging and monitoring for AWS account activity rather than snapshot management. AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources, but it does not automate the lifecycle of EBS snapshots like Data Lifecycle Manager does.
