WebSphere architecture consists of one or more COMPUTER systems which are called nodes. Nodes are AVAILABLE within WebSphere cell. A WebSphere cell can have one node. On this node all the needed softwares installed. If a WebSphere cell contains more than one node, then all the software COMPONENTS are distributed among the nodes. The software components that are installed in one node can share in the distributed environment. This DISTRIBUTION enables for scalability, reliability.
The following are the components:

• A web server which provides the services of HTTP
• A database server for DATA persistence
• WebSphere Application Server (WAS)
