This work adresses the service level agreements life cycle in service-oriented architectures. This life cycle starts with a specification and a modeling phase of the required quality levels. The second phase of this life cycle consists in negotiating these levels. This phase is accomplished by signing a service level agreement by the client and the provider. The last phase consists in monitoring the obligations defined in the SLA until the termination of its validity period. Concerning the first phase, we noticed that the existing SLA models are incomplete especially if the required service levels have to be indirectly computed according to other elementary quality metrics. To overcome this problem, we defined a new SLA model named SLAOnt. Regarding the second phase, we noticed that the existing SLA negotiation approaches consist in choosing a subset of clauses and values among choices predefined by the provider. However, the client may not understand these choices if he is not an expert of the IT domain. For this reason, we propose a novel negotiation approach based on a semantic matching of quality of service objectives between clients and providers. This phase ends with a generation of a complete service level agreement in case of compatibility. Concerning the monitoring phase, we noticed a lack of an automatic and a generic approach to facilitate the task of supervision and detection of the SLA violations. To address these shortcomings, we establish a monitoring approach based on inferential reasoning to detect violations
