摘要：Cloud computing is gaining huge attention these days. Service level agreements play a crucial role in cloud computing. A provider offering good SLA will always have an edge over other providers in market as consumers would prefer the cloud that offers good SLA as compared to others. Service level agreements help a cloud consumer to choose the best cloud by matching his requirements with the services offered by clouds as mentioned in their service level agreement. However, this process of matching becomes quite complicated when performed manually by a cloud customer. The reason for the same can be attributed to increasing number of providers offering services with growing popularity of cloud computing. As a result a consumer may make a wrong decision and thus risk his entire business on an unsuitable cloud. Hence, keeping the above issue in mind we propose a framework that removes the burden of selection from the customer by automatically selecting the best cloud for a user. The given approach selects the most suitable cloud by comparing different clouds on the basis of service they offer and on the basis of user requirements and priorities.
