Autonomic Replication of Management Data Evaluation of a Market-based Approach

This paper describes work in progress whereby a dynamic data replication scheme, under market-based control is applied to a proposed autonomic distributed data layer for managing configuration management data. The scope of the proposed autonomic system is described and also some experimental work are presented. Analytic approximations of the performance achieved for management requests under various static data replication schemes are compared with event-based simulations of the same system under dynamic market-based replication control. The purpose of this comparison is to evaluate the performance and suitability of a market-based control approach for such autonomic replication systems
