Abstract: Nowadays, hosting centres are widely used to host various kinds of applications (e.g., web servers or scientific applications). Resource management is a major challenge for most organisations that run these infrastructures. Many studies show that clusters are not used at their full capacity which represents a significant source of waste. Autonomic management systems have been introduced in order to dynamically adapt software infrastructures according to runtime conditions. They provide support to deploy, configure, monitor, and repair applications in such environments. In this paper, we report our experiments in using an autonomic management system to provide resource aware management for a clustered application. We consider a standard replicated server infrastructure in which we dynamically adapt the degree of replication in order to ensure a given QoS while minimising energy consumption.

Keywords: energy consumption; energy management; replication; autonomic computing; energy-QoS tradeoffs; QoS; quality of service; J2EE hosting centres; resource management; autonomic management systems; clusters; software infrastructure.
