A Quantitative Evaluation Method Based on Hierarchical Architecture Model of Cloud Service Availability

Abstract:

Today, cloud service has evolved as a network centric, service oriented computing model. Consumers purchase computational resources and network accesses on demand without worrying about the underlying technologies used. However, the concerns of security, reliability and service response availability are also increasing. Although cloud service providers usually committed to the availability scope of Service Level Agreement (SLA), most cloud tenants do not understand the inherent complexity. There is an apparent lack of ability to assess the risks when choosing cloud platform. From the perspective of the cloud computing service layer model, this paper defines and analyses a quantitative evaluation method of the availability of cloud service. And it proposes the concepts of availability unit (AU), availability set (AS), standalone availability (SA) and deployment availability (DA). Also discusses the algorithm relationships among all levels of IaaS, PaaS and SaaS on cloud computing service.
