Dynamic shared server resource allocation

A computer program product stored on a non-transitory computer readable storage medium, which when executed by a computing system, provides a resource allocation system controlling allocation of user assignments to a plurality of server systems managed by a shared resource manager of a service provider, the program product comprising:

• program code that generates a resource request interface receiving user request parameters from a first user for identifying a desired server resource;
• program code that generates an option calculator that calculates a plurality of user assignment alternatives based on migration of user assignments of at least a second user to make the desired server resource available to the first user;
• program code that generates a downtime calculator that calculates a predicted downtime for each of the plurality of user assignment alternatives;
• and
• program code that generates a user downtime cost calculator that calculates a predicted business cost for at least the second user based on the predicted downtime and a transaction value per time factor for the second user,
• wherein the migration request interface provides the predicted downtime and the predicted business cost for at least one of the plurality of user assignment alternatives to at least the second user prior to the second user accepting at least one of the plurality of user assignment alternatives.
