The following article describes the issue of a Data Center environment testing with use of a generic model of a cloud-based telecommunication service. The Authors present a process of creation and selection of unique system properties, in order to design the generic model of a cloud-based telecommunication service. Layered structure of the presented model depicts complexity of resulting testing procedures. Definition of a genuine polynomial state equation of a cloud service, as well as a generic architecture of the cloud service testing environment are therein discussed.
