SLA-Driven Cloud Computing Domain Representation and Management

I would like to thank my family and friends for the support given in the years of the making of this Ph.D. Thesis. I Summary Service Level Agreements (SLA), as well as all its concerning facets such as SLA definition language, negotiation, monitoring, etc., have been subject of research for years, but the advent of Cloud comput-ing, and the need of means for defining and ensuring Quality of Service (QoS) levels have greatly increased the interest on these developments. As the size and complexity of Cloud systems increases, the manual management of these platforms becomes a challenging issue. There-fore, the automation of large scale systems management is another promising feature of the SLA-driven autonomic Cloud solutions. Ad-ditionally, SLA-driven Clouds need mechanisms to represent, store and retrieve the information related to their particular domain. Usuall
