WebSphere Application Server
The base application server product, WebSphere Application Server, provides full support of the J2EE 1.3 specification, the server-side Java runtime environment, and administrative tools for managing the environment.
WebSphere Application Server Network Deployment
The Network Deployment product provides all the functions of the base product and some additional functions, including support for highly available multiple-system configurations, centralized administration of multiple nodes, and advanced Web services components.
