الملخص الإنجليزي

Cooperative services in Service Oriented Architectures (SOA) interact and delegate jobs to each other; when they have to respect a Service Level Agreement (SLA) they need to explicitly manage it amongst each other.

SLAs and, above all, security-SLAs, are usually expressed in ambiguous ways and this implies that they need to be manually evaluated both in a mutual agreement to "qualify a service" and in the monitoring process.

Due to this approach, usually, service composition cannot be dynamically performed.

In this thesis we introduce a methodology which helps in SLA automatic evaluation and comparison.

The methodology was found on the adoption of policies both for service behavior and SLA description and on the definition of a metric function for evaluation and comparison of policies.

Quality attribute requirements play an important role in service selection in a service-oriented architecture environment.

It is easy to find several services that fulfill the functional requirements but fail to meet important quality attribute measures.

Service level agreements provide the architect with a specification of the verifiable quality characteristics that the service will provide.

Such a specification allows the architect to select the service that best supports the system’s quality attribute requirements.

This thesis surveys the state of practice in service level agreement specification and offers guidelines on how to assure that services are provided with high availability, security, performance, and other required qualities.

In addition, this thesis contributes a new philosophy to evaluate the agreements between user and service provider by monitoring the measurable and immeasurable qualities to extract the decision by using artificial neural networks (ANN).
