AWS CloudFormation now allows you to detect if configuration changes were made to your stack resources outside of CloudFormation via the AWS Management Console, CLI, and SDKs. Drift is the difference between the expected configuration values of stack resources defined in CloudFormation templates and the actual configuration values of these resources in the corresponding CloudFormation stacks. This allows you to better manage your CloudFormation stacks and ensure consistency in your resource configurations. For more information on Drift detection, visit the AWS Blog.
Drift detection is available in the following regions: US East (Ohio), US EAST (N. Virginia), US West (N. California), US West (Oregon), Canada (Central), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), EU (Frankfurt), EU (Ireland), EU (London), EU (Paris) and South America (São Paulo).
