Embodiments relate to systems and methods for managing subscribed resource limits in a cloud network using variable or instantaneous consumption tracking periods. A set of aggregate usage history data can record consumption of processor, memory, software, or other resources subscribed to by a user across multiple host clouds. An entitlement engine can analyze the usage history data to identify a subscription margin for the subscribed resources, reflecting under or over-consumption of cloud resources against subscription limits across multiple clouds. The entitlement engine can by default track the short-term subscription margin for one or multiple resources each hour of a day, and/or over other intervals. The entitlement engine can also generate a set of variable consumption periods over which to track the user's resource consumption, based on trends or conditions demonstrated in that consumption pattern. In aspects, consumption can be metered on smaller intervals when the consumption rate is rapidly changing.
