Recently, the trend of Cloud Computing has become a significant impact for IT departments and forms many innovative services by virtualization. Virtual systems have been used and identified on services of different fields nowadays. IT hardware manufacturers such as HP, IBM, Dell, etc..., put a large amount of investments on enterprise server products to support the virtualization environment. Service...
Cloud computing often uses a multi-tenant architecture where tenants share application and system software. Request prioritization presents a challenge in this architecture. Tenant may have individual (local) prioritization requirements, and these requirements can be different for different tenants. The shared application must use a global priority scheme for requests from all the tenants. This paper...
Cloud Computing, with its on-demand provisioning capability on shared resources, has emerged as a new paradigm for reducing IT costs. In this paper, we present the architecture of a provisioning system that simplifies the deployment of complex application services on a Cloud infrastructure. We will introduce the concept of Composite Appliance and explain how it can be implemented and utilized to simplify...
A cloud-based, highly consumable queuing service must provide extreme scalability, flexible models of consistency, and high availability in the presence of network partitions. CAP theorem states that at most two of the three properties - Consistency, Availability, and Partition Tolerance - can be achieved at the same time for any shared data system. This paper presents the design and implementation...
In service-oriented computing, service consumers invoke services deployed by service providers, and service providers are liable to manage the quality of their services including scalability, availability and performance. Especially, scalability is hard to achieve, mainly due to the unknown nature of service consumers and unpredictable volumes of service invocations. Services with poor scalability...
With ever-growing applications of diverse requirements over Internet, traditional inclusion of all applications into the application layer becomes difficult and impractical. Open Network Application Service/Reference Model (ONAS/RM) proposed by SC-Netcom Lab suggests a service-oriented Network Application Service Interface (NASI) be explicitly defined to clearly set the boundary between real applications...
As a typical form of Cloud service, Software as a Service(SaaS) has been leading the adoption of Cloud to enable e-Business by the industries. There are growing number of SaaS services which could provide different aspects of capability enabling business to leverage Cloud platform to run and manage business processes, such as customer relationship management, supply chain management, finance and accounting...
Since cloud computing is a fast-developing business area, many companies seek a more adaptable business model responding to the changing market environment. We propose a value net based cloud computing model after the in-depth study on service delivery and value creation process in cloud computing as well as the current research findings of the value net theory and business model. Furthermore, the...
It is obvious that big, complex enterprise systems are hard to manage. What is not obvious is how to make them more manageable. There are two traditional solutions for management in IT systems. One relies on administrators, but there are lacks of experienced administrators. The other relies on systems themselves, but there are no important progresses in related technologies about self-management,...
Mobile device has become an important tool and component in many businesses and used widely as a successful platform to invent and develop new applications to increase efficiency and reduce cost. Maintaining a fleet of devices for the mobile task force in a secure and scalable fashion is critical to ensure the long-term success of enterprise mobility platforms. Many mobile device management suites...
Multi-tenancy supporting becomes a basic characteristic of Software-as-a-Service (SaaS) operation. In multi-tenancy environment, tenant placement problem is critical for balance the database server workload. In this paper, we discuss how the cross-tenant data access affects the workload and how to optimize resource utilization in tenant placement process. This paper comes up with a SaaS tenant data...
Cloud computing often uses the multi-tenancy architecture where tenants share system software. To support dynamically increasing demands from multi-tenants, the cloud service providers have to duplicate computing resources to cope with the fluctuation of requests from tenants. This is currently handled by virtualization and duplication at the application level in the existing cloud environment, such...
Cloud computing delivery model can significantly reduce enterprise IT costs and complexities. This technology can handle the rapidly gowning environment and provide more flexible resources sharing and hence it has become as anew information technology infrastructure recently. In contrast to traditional enterprise IT solution, cloud computing moves the application software and databases to the servers...
