| Portals |
IntroductionThe Johannes Kepler University in Linz has developed a novel combination of portals which allow the stakeholders to get access to the functionality provided by the different layers of the edutain@grid system. These portals allow a unified and consistent interface approach hiding the complexity of traditional grid applications in order to support users from all different fields to work with edutain@grid in an intuitive way.
Management PortalThe management portal was developed for hosters which participate in this system by providing computing resources. It is implemented following the classic web portal approach so that it can be accessed via any web browser. The portal provides access to the resource management and monitoring functionality of the management layer to allow the hosters to keep an overview about their participating machines.
The portal itself is configured to provide three different views to the hosters:  Configuration view:
Controlling view:
Monitoring view:
 Client PortalThe client portal is developed for the end users of the edutain@grid system which are either computer game players or participants in e-learning application. It provides functions to get information about available ROIA sessions and to connect to running applications. The portal is implemented as a C++ API which will be included in the application clients to provide a common way of access for the different types of client applications. The communication is achieved via web service calls to the Business Layer which allows a secure and standardized way of data transmission.
The key features for the client portal are:
Added ValueFor the edutain@grid system a novel portal concept was developed. To offer interfaces for the different kind of actors the definition of portals has been extended beyond the use of web interfaces. In combination with the different edutain@grid layers the portals provide a unified way of managing and accessing ROIAs.
