Embodiments relate to systems and methods for triggering workload movement based on a policy stack having multiple selectable inputs. A set of aggregate usage history data can record consumption of processor, software, or other resources subscribed to by one or more users in a or clouds. An entitlement engine can analyze the usage history data to identify a subscription margin and other trends or data reflecting short-term consumption trends. An associated policy management tool can receive, build, and update a migration policy stack containing a set of configurable policies that can be applied to the conditions of the workload to determine whether, when, and where to migrate the workload or portions thereof to a new cloud host or hosts. In aspects, the policy stack can include user-selectable policy parameters, such as resource consumption thresholds and/or subscription time periods, which can dynamically vary and/or which can be expressed as functions of other policies or resource-consumption variables. In aspects, the policy stack can have different depths and different individual policies at different times and/or under different operating conditions.
