# AMS-managed application accounts
<a name="application-account-ams-managed"></a>

Application accounts that are fully managed by AMS are referred to as AMS-managed application accounts, where some or all operational tasks, like service request management, incident management, security management, continuity management (backup), patch management, cost-optimization, or monitoring and event management of infrastructure, are performed by AMS.

The amount of tasks performed by AMS depends on the Change Management mode that you select. AMS-managed accounts support different modes for change management:
+ [RFC mode](rfc-mode.md)
+ [Direct Change mode in AMS](direct-change-mode-section.md)
+ [AMS and AWS Service Catalog](ams-service-catalog-section.md)
+ [AMS Advanced Developer mode](developer-mode-section.md)
+ [Self-Service Provisioning mode in AMS](self-service-provisioning-section.md)

For more information about change management and different modes, see [Change management modes](using-change-management.md).

There are some AWS services that you can use in your AMS-managed account without AMS management. The list of these AWS services and how to add them into your AMS account are described in the [Self-service provisioning](https://docs.aws.amazon.com/managedservices/latest/userguide/self-service-provisioning-section.html) section.
