Virtual machines are allocated on demand in virtualized cloud platforms to provide flexible and reliable services. The major difficulty lies in satisfying the conflicting objectives of reducing response time while lowering resource costs. In this paper, a mathematical multi-tier framework for virtual machine allocation is proposed, which can be used to capture the performance of the cloud platform...
This paper presents AMREF, an Adaptive Map Reduce Framework designed for an effective use of computational resources in data center networks to deal with real time data intensive applications. AMREF entails its adaptivity from adaptive splitter, adaptive mappers and adaptive reducers in a stochastic control manner. We use three methods, feedback control, stochastic learning with smooth filter and...

Software as a service (SaaS) is an important technology innovation as well as a business model innovation to bring new opportunities to small and medium enterprises (SME). There are different SaaS provisioning methods, depending on the customer profile, the cost of the required resources, and the price that customers are willing to pay. The core technology of SaaS-ization focuses on multi-tenancy,...
This paper proposes a cloud service model that centers around customer business requirements. The model covers the customers' subscribed services and the service providers' offered cloud services. It covers the relationship among offering versus subscription, cloud infrastructure service versus cloud application service, configuration versus customization of cloud services, etc. It then depicts a...
