Lifecycle Events in AWS Control Tower

Some events logged by AWS Control Tower are lifecycle events. A lifecycle event's purpose is to mark the completion of certain AWS Control Tower actions that change the state of resources. Lifecycle events apply to resources that AWS Control Tower creates or manages, such as organizational units (OUs), accounts, and controls.

Characteristics of AWS Control Tower lifecycle events

For each lifecycle event, the event log shows whether the originating Control Tower action completed successfully, or failed.
AWS CloudTrail automatically records each lifecycle event as a non-API AWS service event. For more information, see the AWS CloudTrail User Guide.
Each lifecycle event also is delivered to the Amazon EventBridge and Amazon CloudWatch Events services.

Lifecycle events in AWS Control Tower offer two primary benefits:

Because a lifecycle event registers the completion of an AWS Control Tower action, you can create an Amazon EventBridge rule or Amazon CloudWatch Events rule that can trigger the next steps in your automation workflow, based on the state of the lifecycle event.
The logs provide additional detail to assist administrators and auditors in reviewing certain types of activity in your organizations.

How lifecycle events work

AWS Control Tower relies upon multiple services to implement its actions. Therefore, each lifecycle event is recorded only after a series of actions is complete. For example, when you enable a control on an OU, AWS Control Tower launches a series of sub-steps that implement the request. The final result of the entire series of sub-steps is recorded in the log as the state of the lifecycle event.

If every underlying sub-step has completed successfully, the lifecycle event state is recorded as Succeeded.
If any of the underlying sub-steps did not complete successfully, the lifecycle event state is recorded as Failed.

Each lifecycle event includes a logged timestamp that shows when the AWS Control Tower action was initiated, and another timestamp showing when the lifecycle event is completed, marking success or failure.

Viewing lifecycle events in Control Tower

You can view lifecycle events from the Activities page in your AWS Control Tower dashboard.

To navigate to the Activities page, choose Activities from the left navigation pane.
To get more details about a specific event, select the event and then choose the View details button at the upper right.

For more information about how to integrate AWS Control Tower lifecycle events into your workflows, see this blog post, Using lifecycle events to track AWS Control Tower actions and trigger automated workflows.

Expected behavior of CreateManagedAccount and UpdateManagedAccount lifecycle events

When you create an account or enroll an account in AWS Control Tower, those two actions call the same internal API. If there's an error during the process, it usually occurs after the account has been created but is not fully provisioned. When you retry to create the account after the error, or when you try to update the provisioned product, AWS Control Tower sees that the account already exists.

Because the account exists, AWS Control Tower records the UpdateManagedAccount lifecycle event instead of the CreateManagedAccount lifecycle event at the end of the retry request. You may have expected to see another CreateManagedAccount event because of the error. However, the UpdateManagedAccount lifecycle event is the expected and desired behavior.

If you plan to create or enroll accounts into AWS Control Tower using automated methods, program the Lambda function to look for UpdateManagedAccount lifecycle events as well as CreateManagedAccount lifecycle events.

Lifecycle event names

Each lifecycle event is named so that it corresponds to the originating AWS Control Tower action, which also is recorded by AWS CloudTrail. Thus, for example, a lifecycle event originated by the AWS Control Tower CreateManagedAccount CloudTrail event is named CreateManagedAccount.

Each name in the list that follows is a link to an example of the logged detail in JSON format. The additional detail shown in these examples is taken from the Amazon CloudWatch event logs.

Although JSON does not support comments, some comments have been added in the examples for explanatory purposes. Comments are preceded by "//" and they appear in the right side of the examples.

In these examples, some account names and organization names are obscured. An accountId is always a 12-number sequence, which has been replaced with "xxxxxxxxxxxx" in the examples. An organizationalUnitID is a unique string of letters and numbers. Its form is preserved in the examples.

CreateManagedAccount: The log records whether AWS Control Tower successfully completed every action to create and provision a new account using account factory.
UpdateManagedAccount: The log records whether AWS Control Tower successfully completed every action to update a provisioned product that's associated with an account you had previously created by using account factory.
EnableGuardrail: The log records whether AWS Control Tower successfully completed every action to enable a control on an OU that was created by AWS Control Tower.
DisableGuardrail: The log records whether AWS Control Tower successfully completed every action to disable a control on an OU that was created by AWS Control Tower.
SetupLandingZone: The log records whether AWS Control Tower successfully completed every action to set up a landing zone.
UpdateLandingZone: The log records whether AWS Control Tower successfully completed every action to update your existing landing zone.
RegisterOrganizationalUnit: The log records whether AWS Control Tower successfully completed every action to enable its governance features on an OU.
DeregisterOrganizationalUnit: The log records whether AWS Control Tower successfully completed every action to disable its governance features on an OU.
PrecheckOrganizationalUnit: The log records whether AWS Control Tower detected any resource that would would prevent the Extend governance operation from completing successfully.

The following sections provide a list of AWS Control Tower lifecycle events, with examples of the details logged for each type of lifecycle event.

`CreateManagedAccount`

This lifecycle event records whether AWS Control Tower successfully created and provisioned a new account using account factory. This event corresponds to the AWS Control Tower CreateManagedAccount CloudTrail event. The lifecycle event log includes the accountName and accountId of the newly-created account, and the organizationalUnitName and organizationalUnitId of the OU in which the account has been placed.

`PrecheckOrganizationalUnit`

This lifecycle event records whether AWS Control Tower successfully performed prechecks on an OU. This event corresponds to the AWS Control Tower PrecheckOrganizationalUnit CloudTrail event. The lifecycle event log contains a field for the Id, Name, and failedPrechecks values, for each resource on which AWS Control Tower has performed prechecks during the OU registration process.

The event log also contains information about the nested accounts on which the prechecks were performed, including the accountName, accountId, and failedPrechecks fields.

If the failedPrechecks value is empty, it means that all prechecks for that resource passed successfully.

This event is emitted only if there is a precheck failure.
This event is not emitted if you are registering an empty OU.
