Fuente: WIPO "sustainability" Mechanisms are provided for processing requests regarding user application data in accordance with sustainability metrics and limits. The mechanisms include a sustainability data management (SDM) controller that receives a designation of a SDM policy to be applied to user application data and specifies a sustainability limit. The SDM controller receives, from agents deployed to a computing system, SDM data collected from sensors. Sustainability metric(s) for computing devices of the computing system are determined based on the SDM data. In response to receiving a request targeting user application data, computing device(s) are selected, based on the sustainability metric(s) and the sustainability limit of the SDM policy, with which to process the request. The request is then processed using the selected computing device(s) of the computing system.
