摘要: Cloud is strongly emerging as the new deal of distributed computing. One reason behind success its business/commercial-oriented nature, proof effectiveness and applicability to real problems. There are actually a lot open-private infrastructures aiming at providing dynamic-on demand resource provisioning according IAAS paradigm. To this purpose they usually apply best effort policy, without taking into account service level agreements (SLA) related quality (QoS) requirements. In such context, main goal Cloud@Home implement volunteer-Cloud paradigm which allows aggregate infrastructure providers. work we specifically focus on SLA-QoS aspects, describing how provide SLA based QoS guarantees through top non-QoS oriented Providers. Aim paper demonstrate can fulfil goal, specifying architecture, algorithms components that management features.
