Service-Orientation in the Computing Infrastructure

This paper discusses service-orientation concepts applied to infrastructure orchestration and management. It discusses the concept of service-oriented infrastructure (SOI) and illustrates examples of end-to-end infrastructure services including services provisioned at the bare-metal hardware level. This paper demonstrates the potential to make platform as a service (PaaS) and its value to the IT infrastructure management

UCSOA: User-Centric Service-Oriented Architecture

This paper introduces a new user-centric service-oriented architecture (UCSOA) that allows end users to compose applications. UCSOA is an extension of consumer-centric service-oriented architecture (CCSOA), which is an extension of conventional SOA. The conventional SOA is producer-centric because service providers publish their services and service consumers must search available services to compose their applications. CCSOA is different as it allows consumers publish their needs including workflows and services, and let producers to produce services to meet the requirements. Based on CCSOA, UCSOA provides support for end users. An application builder is an engineer who has both domain and programming knowledge, while an end user has little knowledge on programming and thus UCSOA needs to allow nontechnical persons to compose their applications. This paper presents the concepts, architecture, enabling techniques, and illustrative examples

A novel cloud computing paradigm for China railway application

Mobile computing is an ever-growing research area. Owing to temporary limitation of current mobile hardware technology and intrinsic mobility, computation on mobile devices will always be a compromise in most research work. Mobile computing can seamlessly augment the cognitive and collaborative abilities of users by using compute-intensive or interactive capabilities in computing system. With cloud computing technology emerging, mobile computing has widely solution supporting. In this paper, we propose a kind of cloud-augment mobile computing (CMC) concept, and express the meaning of its implement. Through china railway application scenario, we discuss the railway emergency disposing system based on the CMC concept, and expatiated on its design and implement for mobile device to utilize the capability of cloud infrastructure and technology.

Evolution of the Intel's e-business data center toward a service-oriented infrastructure

This paper brings a historic perspective of the Intel e-business data center growth from supporting a simple static Web site to a leading e-business implementation, one of the worlds largest and most complex installations of its type. It outlines the challenges facing IT and e-business operations today and calls out the needs for more advanced platform and service manageability technologies. To cope with these new challenges, the paper introduces the concept of service-oriented infrastructure (SOI), its architecture, key technical components, business benefits, and key steps to of the evolution toward SOI

IT and Business Integration through the Convergence of Virtualization, SOA and Distributed Computing

Technologies associated with virtualization, SOA and grids in the sense of distributed computing have been on a convergence path during the past few years. This convergence allows separating data from the application that uses the data and from the computers that run the applications. Although new applications are certainly possible, perhaps the most revolutionary aspect of this convergence are the non-functional capabilities it brings, namely, the ability to deploy applications at a fraction of the time and cost compared to more traditional methods. Large, monolithic traditional applications will become an expensive minority in this service oriented environment. In their place, applications will be assembled as composites from smaller, granular services. We call these service components servicelets.We conclude that servicelets will play an increasingly important role in future IT organizations, as they will offer the agility and cost-effectiveness solutions businesses have been requesting for years. Virtualization, SOA and distributed computing technologies will define a new paradigm for application development and delivery promising radical reductions in development cost while accelerating the speed of deployment by orders of magnitude as compared with todaypsilas methods.

Architecting the Service Oriented Data Center

The adoption of SOA in business computing environments is growing due to the promise of significant cost reduction in the planning, deployment and operation of IT projects. However, the organic transformation from legacy enterprise applications to SOA applications only has been seen mostly in large enterprises datacenter where services are centralized. This paper discusses the effect of SOA, and specifically the effect of Outside-In SOA previously defined in the increasingly decentralized way in which data centers are deployed and managed. Patterns of adoption of SOA, in combination with emerging technologies lead us to believe that the traditional datacenter owned by a large organization, i.e., the traditional monolithic data center, will evolve into a more federated form, with horizontal specialization creating opportunities for smaller players and emerging economies. The decentralization of the physical datacenter will take place through federated services offered from distributed service providers. This new dynamic will affect large and small business alike.

Resource management policy for cloud testbed of China railway

Cloud provides a shared resource pool for different independent or dependent applications. The virtualization techniques and power management techniques can enhance the flexibility with consolidate multiple virtual machines on the physical server. A key challenge is to automate the management of virtual servers while taking account of application requirements, resource utility and so on. This paper proposes a policy for control virtual machines configuration and resource allocation with the aim of dynamic placement of virtual machines and reducing the power consumption. We use utility function to establish the mathematical model to support decision for resource management and validate our approach through cloud testbed for railway application.

Automation Under Service-Oriented Grids

For some companies, information technology (IT) services constitute a fundamental function without which the company could not exist. Think of UPS without the ability to electronically track every package in its system or any large bank managing millions of customer accounts without computers. IT can be capital and labor intensive, representing anywhere between 1% and 5% of a companyʼs gross expenditures, and keeping costs commensurate with the size of the organization is a constant concern for the chief information officer (CIO)s in charge of IT.

Governance under federated technology development

This paper summarizes the concept of Federated Technology Development (FTD) and explores requirements for a governance structure necessary to make FTD work in an organization.
