Research Relevance and Potential Impact

Cloud computing is an evolving field of research and development; it reveals different research

challenges including for instance security, scalability, vendor lock in, and SLA management.

Federated Clouds add more challenges induced by the dynamicity and continuously changing

and volatile environment. Among these challenges involve developing mechanism to manage

features related to the federation of Clouds through collaborative networking. SLA management

in federation of Clouds remains a very relevant research initiative that addressed the dynamicity

of relationships established between different Cloud services. Multi-level SLA specification,

negotiation and monitoring are the core contributions that we propose in this research thesis

to respond to a need for a flexible, scalable, and maintainable collaborative environment.

The adoption of game theory allows automated SLA negotiation and supports customers and

providers to reach fair agreements while satisfying some QoS properties. Adaptive agent-based

SLA monitoring detects efficiently causes of QoS violations and reacts with some corrective

actions to maintain an uninterrupted service provisioning.

The result of this work will have an impact for researchers working on the area of Cloud

computing, especially in federated Clouds environment. It will also inspire more investigation

and extensions to cope with other aspects, such as SLA enforcement that were not considered

in this work. The output of this research has been demonstrated by well-indexed publications

that can contribute toward this direction.
