WebSphere Application Server V6 Scalability and Performance Handbook

This IBM Redbook discusses various options for scaling applications based on IBM WebSphere Application Server Network Deployment V6. It explores how a basic WebSphere configuration can be extended to provide more computing power by better exploiting the power of each machine and by using multiple machines. It examines a number of techniques:
- Using the IBM WebSphere Edge Components Load Balancer to distribute load among multiple Web servers
- Using the WebSphere Web server plug-in to distribute the load from one Web server to multiple application servers in a server cluster
- Using the WebSphere EJB workload management facility to distribute load at the EJB level
- Using dynamic caching techniques to improve the performance of a Web site
- Using the HAManager to meet high availability needs of critical applications
- Using application development best practices to develop a scalable application
- Using the performance tuning options available with WebSphere to adjust the application server configuration to the needs of your application

This redbook provides step-by-step instructions for implementing a sample, multiple-machine environment. We use this environment to illustrate most of the IBM WebSphere Application Server Network Deployment V6 workload management and scalability features.
