Cloud computing is basically an internet based computing, whereby shared configurable resources are provided to cloud service consumers as services on demand. As an increasing growth of cloud computing, many enterprises provide different cloud services to cloud service consumers. From cloud service consumer's perspective, it is difficult to choose an appropriate cloud service that satisfies the...

A special Genetic Algorithm (GA) with simplex optimization method is proposed for the problem of selecting an optimal cloud service composition plan from a lot of composite plans on the basis of some global Quality-ofService (QoS) constraints. In this GA, some Simplex Method (SM) operations and a fitness function are provided. The design of the SM operations is made in the light of the characte...

The cloud infrastructure services landscape advances steadily leaving users in the agony of choice. Therefore, we present CloudRecommender, a new declarative approach for selecting Cloud-based infrastructure services. CloudRecommender automates the mapping of users’ specified application requirements to cloud service configurations. We formally capture cloud service configurations in ontology a...

Cloud consumers (CC) are confounded while taking the choice of selecting Cloud service provider (CSP) to accomplish Cloud services. Large number of CSPs are present in the market, which provide diverse cloud administrations viz Platform-as-a-Service PaaS, Infrastructure-as-a-Service IaaS and Software-as-a-Service SaaS. CSPs are conveying their Cloud services to CC in light of Service Level Agre...

With the growing demand and commercial availability of cloud services, the need for comparison of their functionality against different prices and performance has arisen. A relevant and fair comparison is still challenging due to diverse deployment options and dissimilar features of different services. This paper addresses a hybrid multi-criteria decision-making model involving the selection of...

Exceptional characteristics of Cloud computing has replaced all traditional computing. With reduced resource management and without in-advance investment, it has been victorious in making the IT world to migrate towards it. Microsoft announced its office package as Cloud, which can prevent people moving from Windows to Linux. As this drift is escalating in an exponential rate, the cloud environ...

Cloud Computing represents a shift in technology and IT (information technology) service management and it opens up possibilities to build new organizational configurations. As in IT outsourcing, the selection of the right partner/vendor is of crucial importance. Thus, in this article we present a partner selection process for four Cloud Computing Environments: public cloud, community cloud, cl...
