Introduction Business expand from a single region to global a. b. The resources of one organization are geographically distributed VO is the dynamic ensembles of resources and Different organizations which need sharing of their it spans from small corporate in the same resources are separated. physical location to large groups of organizations Dynamically package Web-plus-Grid spreading out across the globe. services into one servicing group and use this kind of servicing group to meet the requirements of resources and business process so that to serve for Virtual Organization

What is Web-plus-Grid services? Web services web services can be interpreted Grid computingthe format of integration XMLsoftware-components with as defines is aimed at of geographically distributed resources information; certain self-descriptive and WSDL hardware definition of a including specifies the(storage capacities, encapsulated functionalities Open Grid web service; computingcan be remotely. Service capacities), software and which used to preserves invoked UDDI is data to services directory. combined by cooperatively complete a task. Architecture web can be loosely and SOAP defines the enveloping rules utilizing standardized protocols. of messages and transport options; ( OGSA) Share resources Grid Computing

What is Web-plus-Grid services? Web-plus-Grid services is based on Open Grid Service Architecture ( OGSA) proposed by Global Grid Forum (GGF). A. B. It takes advantages of the standardized interfaces and communication protocols provided by Web services technology; It based on the logical architecture and predefined capabilities provided by OGSA. All resources including computation facilities, storages, networks, programs, databases can be treated as services and we can packages a set of services into one servicing group to provide capabilities across heterogeneous platforms.

Why choose OGSA and Web-plus. Grid services? Disadvantages of webprovided by OGSA: Seven capabilities services A. B. Lack of capabilities for effectively integrating large scale of a)enterprise resources Infrastructure Services b)Lack of abilities for deploying self-performance Execution Management Services c)management to efficiently coordinate different workflows Data services within a virtual organization d) Resource management services Benefits of OGSA and Web-plus-Grid services A. B. C. e)OGSA takes advantage of Grid Computing, and Grid Security Services f) Computing is designed for handle large scale of resources. Self-management Services g)Use Three Logical ties of OGSA to construct servicing Information Services group according to the demands of virtual organizations Using seven predefined capabilities to guide the package of web plus grid services

How to package services for ONE servicing group? Web-plus-Grid services Capabilities of OGSA Virtual Organization System A set of capabilities of OGSA can be selected to support virtual organization. And these capabilities are composed by a set of Webplus-Grid services.

Resources Virtualization Resources virtualization can t reduce transactions for workflow t reuse heterogeneous systems to handle diversified resources in a unified way. The standard protocols and schemas achieve for interoperability. t discover resources with desired attributes and retrieve the properties for users’ needs. It supports for customization.

Group Capabilities from Resources Virtualization Different companies develop their information technology strategies as to t t apply information technology for workflow streamline at the efficient ways Optimize the resources management and keep core competitive activities inside Compete with other companies in virtualization and still attain high autonomy

User Case 1 How to manage diversified services in the information infrastructure? How to manage the service level agreements by outsourcing vendors?

1. OGSA Profile t t Subscribed to application service providers by outsourcing non-core business activities. t 4 Common application service as right components to build its own profile according to the quality of service agreement. Main features are: EAIP – application platform connects to database and web services in the middle wares Portal - interaction between components and manage information service integration. UDDI registry to locate the web services request by delegated users. Web services interfaces can be accessed by SOAP and service delivery in the profiles through enterprise information portal is secured. 1. 3 2. 1 3. 4. 2 Fig. 5. Enterprise Information System Integration Platform

User Case 2 How to discover a specific service needed and meet the specific capabilities? How to organize collections of service to deliver reliable and scalable service for a specific goal?

2. Grid Resource Reseller are looking after different service providers and users. Services are including: 1. Deployment and configuration service for hosting and computing the resources over OGSA. 2. OGSA naming is a job queuing system to check for availability or load balancing purpose. 3. Serving as information service and data management. 4. Monitoring quality of service level and attaining the fault-tolerance 5. Fault detection and recovery services 6. Logging, metering and auditing the performance of components in the whole chain or other non-OGSA service, e. g. billing and provenance that are applied to the execution management service.

User Case 3 How to manage communications within or across virtual organizations? How to establish identity authentication in Grid in order to guarantee security?

3. Virtual Organization Grid Portal Services By configuring the collected resources to the members of VO with high autonomy. t t t secure communication between clients and web/grid services. resource-specific identities are authenticated by private and public key cryptography and operated under the security protocol of X. 509 certificate. build under user delegation mechanisms in the grip map for accessible control and proxy delegation is managed in each service, for instance, data exchange, file staging and job management.

Cases Review Integrating Web Services in following review [1]: t OGSA profiles are used for reconstructing new web services by the assembly of existing service components to users. t Grid Resource Reseller that is a supply chain between the Grid resource owners and end users to optimize resources and concentrate on the core competences by owners and users. By OGSA and web services, the no. of application service providers and Grid resource owners are scaling up in the widen internet based clients. t Virtual Organization (VO) Grid Portal provides its members to various computational, instrument-based data and other types of resources. The change of economics is customer-performance measure and execution management service by configuring the collected resources to the members of VO with high autonomy.

Conclusion t t The capabilities of resources, services and people in different scaling enterprises can be synergized to drive economic growth virtually. The small enterprises are not threatened by the high cost of system implementation in electronic business environment when the availability of web and grid services is so flexible and dynamic fitting for new customization.
