Themarketforcomputing-intensiveservices,suchastheAI-basedservicesisgrowing.Thelarge-scaleapplicationofartificialintelligence(AI)algorithmsacrossvariousindustriesrequiresagreatamountofcomputingpowerresources.Inthistheageofcloudcomputing,thetendencyistobuildcentralizedcomputingpowerresourcespoolstosolvethisproblem.However,insomenewscenarios,thesecentralizedpoolsdonotsatisfyrequirementsasappropriatecomputingpowernodesneedtobeselectedaccordingtotheservicecharacteristics,price,andnetworkconditions.Anaccesscontrolsystembasedonfacerecognition,showninFigure6-1,servestoexplainwhyubiquitouscomputingpowerresourcesareneeded.
