This IBM Redbook discusses various options for scaling applications based on IBM WebSphere Application Server Network Deployment V5.0. 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 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 IBM WebSphere Application Server Network Deployment V5.0 workload management and scalability features.
It is one in a series of handbooks designed to give you in-depth information on the entire range of WebSphere Application Server products. |
