Design issues of a Jini-based Grid system

The technological development of the last decade made it possible to create large-scale, geographically distributed metacomputing or Grid systems, which allow us to share and use scattered resources and large amount of data effectively. The most important requirements against these systems are the effective discovery of available resources, secure access to these resources, and fast adaptation to the changes arising from the dynamic nature of the system. In our paper we discuss the meaning of these properties in a Jini-based Grid system. We show how Jini technology can provide simple and effective solutions to many problems arising in Grid systems using already existing tools. Furthermore, we explain the architecture of a Jini-based Grid system we are developing and discuss the questions emerged during the design of the system.
