Abstract

Publish-Subscribe is one of the important patterns for developing scalable distributed systems. Usually,
the deployment of the publishers and subscribers to the nodes can be done in many different ways,
whereby each deployment alternative will have a different impact on the performance. The many possible
architecture design alternatives tend to trade-off with respect to execution cost and communication cost.
Unfortunately, for the human engineer it is not tractable to define a feasible configuration in case of large
number of nodes and participants. In this paper we propose a generic method to assist the architect
by automatically deriving feasible deployment alternatives of Publish-Subscribe based distributed
systems. The approach is based on the so-called capacitated task allocation problem (CTAP) in which
constraints on memory capacity and processing power are applied to manage the trade-offs between the
total execution cost and total communication cost to derive feasible design alternatives. The method is
supported by our tool framework (Deploy-PS) that provides an integrated development environment
for modeling the Publish-Subscribe deployment architecture, modeling the physical resources and the
performance requirements, and the selection and generation of the feasible deployment architecture
alternatives.
