# Self-managed licenses in License Manager Self-managed licenses (formerly known as *license configurations*) are the core of License Manager. Self-managed licenses contain licensing rules based on the terms of your enterprise agreements. The rules that you create determine how Amazon processes commands that consume licenses. While creating self-managed licenses, work closely with your organization's compliance team to review your enterprise agreements. Self-managed licenses can be used independently within a single Amazon Web Services account or cross Amazon Web Services account or integrated with License asset groups for centralized management across multiple Amazon accounts and regions across Amazon organization. This integration provides enhanced governance, and compliance tracking for enterprise environments. Amazon Web Services services such as License Manager have service quotas that define the maximum number of resources or operations per Region that are available to your Amazon Web Services account for that service. For example, with License Manager, you can have a maximum of `10` self-managed licenses per resource, with no more than `25` self-managed licenses total in any given Amazon Web Services Region. To find out more about License Manager quotas, see [Amazon License Manager Service quotas](https://docs.amazonaws.cn/general/latest/gr/licensemanager.html#limits_license-manager-quotas) in the *Amazon Web Services General Reference*. **Note** Systems Manager managed instances must be associated with vCPU and instance type self-managed licenses. **Topics** + [Parameters and rules](config-overview.md) + [Build rules from vendor licenses](licenses-to-rules.md) + [Create a self-managed license](create-license-configuration.md) + [Share a self-managed license](share-license-configuration.md) + [Edit a self-managed license](modify-license-configuration.md) + [View self-managed licenses](view-license-configuration.md) + [Deactivate a self-managed license](deactivate-license-configuration.md) + [Delete a self-managed license](delete-license-configuration.md) + [Self Managed License Rules](license-rules.md)
