We introduce a self-control integrated service component aiming at ensuring Service Level Agreement management. Our approach based on quality of service has two important points: the contract description (supply and demand) and the contract management. The self-control in service components allows us to react dynamically (operational decision) and the autonomic loop enables us to manage the services composition in a virtual session (tactical and strategic decision). This approach is proposed in the OpenCloudware project. We also provide an example of self-control cloud services through the Springoo application.
