A job is submitted into a first selection of resources in a grid environment from among a hierarchy of discrete sets of resources accessible in the grid environment. Discrete sets of resources may include locally accessible resources, enterprise accessible resources, capacity on demand resources, and grid resources. The performance of the first selection of resources is monitored and compared with a required performance level for the job. If the required performance level is not met, then the discrete sets of resources are queried for available resources to meet the required performance level in an order designated by said hierarchy. Available resources in a next discrete set of resource from the hierarchy of discrete sets of resources are added to a virtual organization of resources handling the job within the grid environment.
