In Cloud Computing

Cloud computing, (also Grid computing and service-oriented architecture), use the concept of service level agreements to control the use and receipt of(computing) resources from and by third parties.

Any SLA management strategy considers two well differentiated phases: the negotiation of the contract and the monitoring of its fulfillment in run-time. Thus, SLA Management encompasses the SLA contract definition (basic schema with the QoS (quality of service) parameters), SLA negotiation, SLA monitoring and SLA enforcement according to defined policies.

The main point is to build a new layer upon the grid, cloud or SOA middleware able to create negotiation mechanism between providers and consumer of services.
