摘要：Cloud Computing lifts the borders betweenthe access control domain of individuals’and companies’ IT systemsby processing their data within the applicationframeworks and virtualizedruntime environments of Cloud serviceproviders. A deployment of traditionalsecurity policies for enforcing confidentialityof Cloud users’ data wouldlead to a conflict with the availabilityof the Cloud’s software services: confidentialityof data would be assured butCloud services would not be availablefor every user of a Cloud. This stateof-the-art contribution shows the analogyof the confidentiality of externaldata processing by Cloud services withmechanisms known and applied in privacy.Sustainability in Cloud is a matterof privacy, which in Cloud is called “isolation”.
