Abstract: Cloud computing represents an opportunity for IT users to reduce costs and increase efficiency providing an alternative way of using IT services. Elastic provisioning plays an important role by giving the possibility to get the best resources configuration that satisfies the application requirements. Even if there are many cloud providers, with a rich and various offer of technological solutions, above all at IAAS, however there is neither support of SLA negotiation, nor of SLA management yet. One of the most important issue in such a context is the lack of negotiation interfaces and mechanisms by current providers for dynamic provisioning, which instead only make available a configuration form to submit the request for a specific resource among the available ones. In this paper, we propose the design of a tool for SLA-based dynamic provisioning of cloud resources at IAAS, that offers to the user negotiation and brokering facilities by integrating multiple models. We present a prototype implementation of our architecture using the mOSAIC framework.
