A Dynamic Architecture for Reconfiguration of Web Servers Clusters

摘要

The allocation planning of resources in a web server cluster is accomplished nowadays by the administrator. Once the internet is quite dynamic, as far as the use of resources is concerned, such a task may be considered critical and inefficient if accomplished manually. Our approach benefits from the use of agents to learn from the environment and adjust automatically the behavior of the system to make a better use of the available resources. With this approach it is possible to help the administrator by minimizing your stress in moments of work overload. The conception, specification, adopted allocation planning strategy, modeling in Petri nets, implementation of this platform in the Java language are presented. Experimentations and simulations which prove the efficiency of the proposal are presented
