摘要

云联合允许各个云提供商动态协作,以服务水平协议(SLA)中商定的服务质量(QoS)目标向其最终用户提供服务。然而,当前的联邦云模型并不面向qos或支持sla。本文提出了一个面向qos的联邦云计算框架,其中多个独立的云提供商可以无缝合作,提供可扩展的qos保证服务,并讨论了联邦组件的高级体系结构。所建议的联合框架的独特特点是它面向QoS,可以跨多个提供者触发按需资源供应,因此有助于最大化QoS目标和资源使用,消除SLA违反并增强SLA形式化。

A QoS-Oriented Inter-cloud Federation Framework
Cloud federation allows individual cloud providers dynamically collaborate to offer services to their end-users with the Quality of Service (QoS) targets agreed in the Service Level Agreements (SLA). However, the current federated cloud models are not QoS-oriented or SLA-aware. This paper proposes a QoS-oriented federated cloud computing framework where multiple independent cloud providers can cooperate seamlessly to provide scalable QoS-assured services and discusses a high level architecture of the federation components. The distinct features of the proposed federation framework is its QoS-orientation that can trigger the on-demand resource provisioning across multiple providers, hence helping to maximize QoS targets and resources usage, eliminate SLA violations and enhance SLA formalization.
