Managing Performance of Clustered Applications ABSTRACT
As more enterprises turn to J2EE to deliver their mission-critical applications over the Web, there is a greater reliance on clusters to provide mission-critical services to ensure maximum service availability and scalability. The challenges in clustering a J2EE application can be attributed to the very nature of distributed computing. Clusters promise to bring affordable mainframe-level computing power and reliability, using cost-effective servers. But clustering also introduces increased management complexity and amplifies the need for new transaction-level management approaches that can address the management complexity from a service delivery perspective.
