SERVICE COMPOSITION MECHANISMS IN THE MULTI-CLOUD ENVIRONMENTS: A SURVEY

Abstract

Cloud computing is a serious technological creation in the area of information systems development that supplies the benefits of self-service applications, source mixing, and wide network access. Nowadays, cloud computing to support fastness, easy combination, and low-cost of distributed applications in dissimilar environments have become increasingly famous. Therefore, service combination is a growing method that proliferates the number of applications of cloud computing by reusing attractive services. In this article, we survey the service composition mechanisms such as all clouds, base cloud, smart cloud, COM2 and clustering algorithms which have been used in the cloud environments. Service composition methods can be applied in two main environments: single and multicloud where due to the importance of multi-cloud environments (MCE), some existing and important methods are analyzed in the multi-cloud environment in this article. This paper also provides a discussion of existing methods in terms of running time and finding the optimal cloud composition. Obtained results showed the performance of each method in some terms.
