IBM WebSphere V5.1 Performance, Scalability, and High Availability WebSphere Handbook Series

This IBM Redbook discusses various options for scaling applications based on IBM WebSphere Application Server Network Deployment V5.1. 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 clustering solutions such as HACMP to meet the 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 book 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 V5.1 workload management and scalability features.
