Container for the parameters to the ModifyIdentityIdFormat operation. Modifies the ID format of a resource for a specified IAM user, IAM role, or the root user for an account; or all IAM users, IAM roles, and the root user for an account. You can specify that resources should receive longer IDs (17-character IDs) when they are created.
The following resource types support longer IDs: instance | reservation | snapshot | volume. For more information, see Resource IDs in the Amazon Elastic Compute Cloud User Guide.
This setting applies to the principal specified in the request; it does not apply to the principal that makes the request.
Resources created with longer IDs are visible to all IAM roles and users, regardless of these settings and provided that they have permission to use the relevant Describe command for the resource type.
