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.
