Abstract: Rapid technological developments in Information Technology (IT) and ubiquitous Internet access are causing serious challenges in service provisioning and resource management landscapes. Cloud computing is proving to be a reliable technology to address these challenges. Service provisioning in the Cloud relies on Service Level Agreements (SLAs) representing a contract signed between the customer and the service provider including non-functional requirements of the service specified as Quality of Service (QoS) and penalties in case of violations. Flexible and reliable management of resources and SLA agreements are of paramount importance to both Cloud providers and consumers. On the one hand, providers have to prevent SLA violations to avoid penalties and on the other hand, they have to ensure high resource utilization to prevent costly maintenance of unused resources In this paper, we propose a novel Cloud management infrastructure, which is based on holistic monitoring techniques and mechanisms for low-level resource metrics to high-level SLA mapping, application scheduling and deployment, and the ability to monitor multiple application executing on the same host.
