Creating an organization involves specifying leases. Leases provide a level of control over an organization's storage and compute resources by specifying the maximum amount of time that vApps can be running and that vApps and vApp templates can be stored.
The goal of a runtime lease is to prevent inactive vApps from consuming compute resources. For example, if a user starts a vApp and goes on vacation without stopping it, the vApp continues to consume resources.
A runtime lease begins when a user starts a vApp. When a runtime lease expires, vCloud Director stops the vApp.
The goal of a storage lease is to prevent unused vApps and vApp templates from consuming storage resources. A vApp storage lease begins when a user stops the vApp. Storage leases do not affect running vApps. A vApp template storage lease begins when a user adds the vApp template to a vApp, adds the vApp template to a workspace, downloads, copies, or moves the vApp template.
When a storage lease expires, vCloud Director marks the vApp or vApp template as expired, or deletes the vApp or vApp template, depending on the organization policy you set.
For more information about specifying lease settings, see Configure Organization Lease, Quota, and Limit Settings.
Users can configure email notification to receive a message before a runtime or storage lease expires. See Setting User Preferences for information about lease expiration preferences.
