摘要:
A system and methods for modeling and analyzing Quality of Service (QoS) characteristics of federated cloud services in an open eco-system is disclosed. A plurality of system entities of a federated service system are identified, and each of the system entities is classified to provide a plurality of entity classifications. A plurality of inter-entity relationships of the system entities are identified, and each of the inter-entity relationships is classified as a primitive model to provide a plurality of inter-entity relationship classifications. A composite model of the federated service system comprising the system entities, the entity classifications, the inter-entity relationships, and the inter-entity relationship classifications is generated.
