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.
