1. A method, in a data processing system comprising at least one computing device and a plurality of computing resources, for migrating a computing environment entitlement contract from one computing resource to another, comprising: generating, by the at least one computing device, one or more computing environment entitlement contract (CEEC) data structures, each CEEC data structure defining terms of a business level agreement between a contracting party and a provider of the data processing system, wherein the terms of the CEEC specify a set of computing resources having a specified configuration, and further specify that the set of computing resources are to be used by the contracting party for a specified purpose at a specified level and pattern of intensity for a specified period of time; associating, by the at least one computing device, the one or more CEEC data structures with a computing resource cohort, wherein the computing resource cohort is a collection of computing resources having similar configurations; identifying, by the at least one computing device, a seller of a CEEC data structure, in the one or more CEEC data structures; identifying, by the at least one computing device, a buyer of a CEEC data structure, in the one or more CEEC data structures; migrating the CEEC data structure from the seller to the buyer; and executing workloads in accordance with terms specified in the CEEC data structure at the buyer after migrating the CEEC data structure from the seller to the buyer, wherein the seller and the buyer are computing resources or collections of computing resources.
