Disclosed embodiments relate to virtual pooling of a local resource in a balloon network. In an example, a balloon network has geographic zones, including at least a first and a second geographic zone. Further, each balloon has a sustainable utilization rate for a local resource. Each balloon utilizes the local resource according to a respective first utilization rate when located in the first geographic zone and utilizes the local resource according to a second utilization rate when located in the second geographic zone. For one or more of the balloons, the sustainable utilization rate is less than the respective first utilization rate and greater than the respective second utilization rate. However, the balloons are operable to move between the geographic zones such that the first utilization rate is substantially continuous in first geographic zone.
