The emulator is flexible and capable of emulating any number of cloud storages, simultaneously . The performances of the providers in this emulator have been set up to act like the performances of Google Cloud storages services , Amazon S3 , Microsoft Azure Storage, and Rackspace Cloud File; which have been measured using the extit{performance analysis services} of the "cloudharmony.com".
