Platform Support
All specified platforms, except zLinux and IA-64 not supported
All specified platforms as Network Deployment
WebSphere Application Server – Network Deployment •Targets multiple servers, multiple nodes environment – Focus is on scalability, availability, and performance – Clustering and failover support – Web server plug-in supports weighted workload management •Distributed administration – XML-based repository – Browser based administration console for the entire topology •Edge components – Load balancer – Switch consultants for CISCO and Nortel switches •Site selector for scaling network dispatcher – Caching proxy •Reverse proxy, content-based routing •Dynamic content caching: integration with WAS servlet caching •Enhanced Web services functions – UDDI registry - for private UDDI registry – Web services gateway
Important Points •All V6 application servers have the same core and base functionality •WebSphere Application Server - Express V6 node can be upgraded to a WebSphere Application Server V6 node –Can be done without any software upgrades –Only a paper license upgrade is required •WebSphere Application Server- Express V6 and WebSphere Application Server V6 node can be federated into a WebSphere Application Server - Network Deployment V6 cell –Can be done without any software upgrades –Only a paper license upgrade is required
