We present a formal policy language (C2L) for stating permissible cloud congurations. Syntactically, C2L is based upon a spatio-temporal modal logic and provides a concise and clear statement of policy constraints for colocation, hosting, migration, security, andavailability.We illustrate the language witha numberof policyspecicationexamples and also present an algorithm forverifying whethera cloud conguration along with its history satisesaC2Lpolicy specication.We provide complexity analysisof the algorithm, and conclude thatC2Lisa useful and viable formalism for specifying and verifying cloud conguration policie
