A 3-tier Grid Architecture and Interactive Applications Framework for Community Grids
Grids originated within the scientific community where the benefits of utilizing an infrastructure that connects and shares resources that are geographically and organizationally dispersed was first realized. Community grids have very different characteristics and requirements to that of scientific grids – the most important being the heterogeneous resource offer and the application demands of the users. The users of this type of grid does not expect to know each and everyone of the resources available, nor does he expect to provide and install his own applications. Additionally, the applications that are usually run by community grid members have one special characteristic – they are very interactive in nature and require quick responses and a communication protocol between the user and the grid. Since the 2-tier architecture of current grids is unable to deal with these special requirements, we propose a 3-tier architecture and an interactive application framework for community grids. Our architecture and framework is able to effectively overcome the problems of application deployment, resource management and interactive execution.
