Technological Considerations
Part of the Lecture Notes in Computer Science book series (LNCS, volume 1364)


The exploitation of new application possibilities, like collaboration and cooperation, offered by distributed systems requires advanced coordination support. Traditional tools are based on the message passing paradigm and lead to asymmetric client/server application architectures. The other - conceptually superior - paradigm uses a virtual shared memory. The development of distributed programs is easier in the latter model and leads to elegant solutions that meet well the new possibilities. We term software support that follows this second approach post-client/server tools. CoKe (Coordination Kernel) is a new middleware layer of this new generation. It particularly eases the development of fault-tolerant, distributed applications.

We discuss, why coordinative data structures (on virtual shared objects) provide more advantages than the traditional method invocation model (on distributed objects).
