随着云计算越来越多地改变了信息技术的格局，组织和企业对软件即服务（SaaS）产品表现出强烈的兴趣，这些产品可以帮助他们提高业务敏捷性并降低其运营成本。他们越来越多地要求满足其功能和非功能要求的服务。鉴于大量的SaaS产品，我们在本文中提出了SaaS供应的框架，该框架依赖于服务消费者和SaaS提供商之间的Brokered服务水平协议（SLA）。云服务经纪人（CSB）可帮助服务消费者找到可以满足其功能和非功能要求的合适的SaaS提供商。拟议的选择算法通过使用总实用程序功能将其产品与服务消费者的要求相匹配，从而对潜在的SaaS提供商进行了排名。此外，CSB负责代表服务消费者与选定的SaaS提供商进行SLA谈判，并执行SLA合规性监控。
As cloud computing is increasingly transforming the information technology landscape, organizations and businesses are exhibiting strong interest in Software-as-a-Service (SaaS) offerings that can help them increase business agility and reduce their operational costs. They increasingly demand services that can meet their functional and non-functional requirements. Given the plethora and the variety of SaaS offerings, we propose, in this paper, a framework for SaaS provisioning, which relies on brokered Service Level agreements (SLAs), between service consumers and SaaS providers. The Cloud Service Broker (CSB) helps service consumers find the right SaaS providers that can fulfil their functional and non-functional requirements. The proposed selection algorithm ranks potential SaaS providers by matching their offerings against the requirements of the service consumer using an aggregate utility function. Furthermore, the CSB is in charge of conducting SLA negotiation with selected SaaS providers, on behalf of service consumers, and performing SLA compliance monitoring.
