Negotiation Policies for Provisioning of Cloud Resources

""Cloud represents today a computing market where users can buy resources according to a pay-per-use business model. Cloud providers offer different kind of services which can be characterized by different service levels. Negotiation of the best resource can be very difficult because there is a semantic gap between the different provider SLAs and the requirements of an user's application. We address the negotiation issue within the research activity of the mOSAIC project by designing and developing an agents based service at platform level for provisioning of cloud resources. In order to allow the execution of the application and fulfill the developer's requirements, the service uses a policy based approach that is able to choose, at infrastructure level, the best solution, in terms of a collection of cloud resources from different providers.""
