Azure Lighthouse includes multiple ways to help streamline engagement and management:
* Azure delegated resource management: Manage your customers' Azure resources securely from within your own tenant, without having to switch context and control planes. Customer subscriptions and resource groups can be delegated to specified users and roles in the managing tenant, with the ability to remove access as needed.
* Etc.
