| Popis: | Publishing the cloud services on the internet has proven to be effective for cloud providers over the internet. To meet user requirements, services should be combined through service composition from multiple cloud domains. In this paper, we proposed an algorithm which composes best QoS aware services with minimal number of cloud combinations which is an NP-hard optimization problem. The proposed algorithm will select a cloud with more number of service files and then we applied PROMETHEE a multi criteria decision making method that selects the best service based on QoS criteria (i.e. Response time, Throughput, Availability, Successability, Price) from optimal cloud combinations. Our experimental results show that the algorithm provides better QoS services with minimal number of clouds by assessing previous benchmarks. |
