QoS Ranking Prediction Framework for Cloud Services J.Subathra, Mrs.P.Latchoumy Abstract— The rising popularity of cloud computing makes building high quality cloud applications a critical and urgently required research problem. QoS rankings provide valuable information for making optimal cloud service selection from a set of functionally equivalent service candidates. To obtain QoS values, real-world invocations on the service candidates are usually required. The existing system focuses on QoS ranking prediction for cloud services by taking advantage of the past service usage experiences of other consumers. This framework requires no additional invocations of cloud services when making QoS ranking prediction. Two personalized QoS …show more content…

Different cloud applications may receive different levels of quality for same cloud services so that the optimal service selection becomes important The QoS ranking of cloud services for a user (e.g., cloud application 1) cannot be transferred directly to another user (e.g., cloud application 2), since the location of the cloud applications are quite different. Some service invocations can produce irreversible effects in the real world. Moreover, when the number of candidate services is large, it is difficult for the cloud application designers to evaluate all the cloud services efficiently. The cloud removes the need for you to be in the same physical location as the hardware that stores your data. There are number of functionally equivalent services in the cloud Due to unreliable internet connections different cloud applications may receive different levels of quality for same cloud services so that optimal service selection becomes important. Cloud computing provides three main services, namely Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). In Software as a Service (SaaS), Clients can use the software that is provided by the provider, which usually need not to be installed on their own machine and they can use the software
