9. 9 Project Goals n Design, implement and validate a layered architecture The layered architecture will be the base platform of GRASP and includes a number of middleware GRID services to simplify the integration of distributed resources and increase the efficiency of applications n Design and evaluate three ASP business models To exploit all basic GRID technologies, there will be a one- to-many, a many-to-many and a federated model n Test project results in real business environments The project results will be evaluated by running three test beds, one in the biomedical, one in the e-learning and one in the financial field

11. 11 Requirements of a sustainable system n Interoperability u Present IT infrastructures are more and more decomposed systems. Therefore the interoperability between different applications on different platforms becomes essential n Security u Security, especially in the ASP market, is one of the most challenging points in distributed systems. This comprises themes like authentication and authorization n Reliability u Obviously this includes the attempt to obtain High Availability. Above that, reliability in the context of GRASP means to guarantee QoS n Scalability u Companies are being challenged by fast changing markets. That requires upgradeable and customisable systems. In the area of outsourcing, scalability comprises the negotiation of appropriate Service Level Agreements

12. 12 Potential Constraints n Lack of grid aware applications u This could be a bottleneck for the migration from current ASP solutions to GRASP. n Lack of key technologies u A slow-down in the development of GRASP related standards could lead to difficulties in the implementation of GRASP middleware. n Emerging new architectures u Some efforts of big players like Microsoft or Sun doing research on distributed, service oriented architectures could compete with parts of the GRASP middleware or make certain parts obsolete. n Technological constraints u Although GRASP aims to be an open, scalable system, there are some basic requirements such as high bandwidth connections. The bandwidth argument for example will lower the usage of GRASP in combination with current mobile devices.

14. 14 Advantages of Grid services n Provision of high computing performance u A Grid is able to provide capacities of such high dimensions that could not be supplied by an average company. u The purchase of computing performance corresponding to the present demand potentially reduces the total costs of ownership (TCO) of a company. n Provision of reliability u Supports the goal of high availability even during maintenance periods. u Protection against accidents and catastrophes. n Provision of dynamic resource combination u Allows the dynamic combination of resources to provide a temporary, but well-fitting, infrastructure for an actual task, not only in the sense of hardware infrastructure but also in the sense of service combination.

15. 15 ASP Business models n One-to-many u The classic ASP model, with one provider and many clients. The services are offered unidirectional. n Many-to-many u Based on P2P relationships, this model allows the integration of provider and user resources, so that also the clients are able to receive an income by providing resources. n Federated model u The federated model is also based on a one-to-many scenario. In contrast to the classic approach, the provider is not a single entity, but consists itself of many actors that combine their resources in order to provide services to their clients.

16. 16 Examples of business opportunities n 1. Financial field: Offer reliable and highly available financial services. As well as in a classic ASP approach, this helps to reduce customer TCO. Moreover, using a Grid reduces also the TCO of the ASP provider. n 2. Biomedical field: Extend the quality of diagnosis in expert systems by the dynamic use of different, predicted data mining results based on data from hospitals. 3. E-learning field: Create a custom tailored learning environment by combining suitable modules from different sources, depending on knowledge and goals of the user.

18. 18 General Assessment and Future Expectations n Assessment : u GRASP aims to introduce a number of technical innovations in the grid area as well as in the ASP area u It is expected that the GRASP infrastructure will enable business innovations that will support cost leadership strategies as well as differentiation strategies n Future expectations u The ASP market will keep on growing, due to the companies efforts to reduce TCO and to build up VPO‘s ( IDC: Compound worldwide annual growth rate of 89% from 2000 to 2005) u Despite of actual economic problems, the area of information technology will also continue to grow. Therefore we expect ongoing improvements of the common infrastructure and specifications, that will help to overcome the identified constraints and make the GRASP project a success.
