1. A method, in a data processing system comprising at least one computing device and a plurality of computing resources, for monitoring a use of the computing resources relative to a computing environment entitlement contract, 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 data structure specify a set of computing resources having a specified configuration that 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; generating, by the at least one computing device, a CEEC cohort comprising a collection of CEEC data structures having similar terms; monitoring, by the at least one computing device, utilization of a collection of computing resources in accordance with the similar terms of the collection of CEEC data structures to identify a usage pattern within the CEEC cohort; and modifying, by the at least one computing device, a membership of a CEEC data structure in the CEEC cohort based on the identified usage pattern.
