HTTP Server The HTTP Server provides the front end to the solution. It allows for greater concurrency and resource off loading from the Portal Server tier, by serving static content (HTML pages, for example) and dynamic content (JSP™ fragments) by way of WebSphere plug-in caching capability. With the Network Deployment configuration, the plug-in provides load balancing among Portal Server cluster members. WebSphere Application Server WebSphere Application Server is a Web application server that provides J2EE services for the WebSphere Portal environment. It executes the Java portlets, JavaBeans™, Java Server Pages (JSP) files, and Enterprise JavaBeans™ (EJBs) that are used by WebSphere Portal. In conjunction with two other products in the WebSphere Application Server family of interoperable products (WebSphere Business Integration Server Foundation and WebSphere Application Server Network Deployment), this component is the platform on which WebSphere Portal runs. WebSphere Portal Server WebSphere Portal Server is a J2EE application that runs on WebSphere Application Server. Its main function is to serve the WebSphere Portal Server framework to the desktops and mobile devices of portal users. WebSphere Portal Server creates an environment that provides the connectivity, administration, and presentation services that are required. WebSphere Portal Server V6.0.1 includes several new functions and enhancements that make it easier to design, administer, and use. Web Content Management Server (Subcomponent) The Web Content Management subcomponent of WebSphere Portal Server empowers a knowledgeable workforce by providing an environment that allows them to create, edit, and publish Web content. Because knowledge owners have less dependence on technical resources, they can publish content in a more timely and efficient way by using the Web Content Management component. It is often helpful to think of a WCM server as a stand-alone component due to performance issues. However, licensing restrictions should be checked. WebSphere Member Manager (Subcomponent) WebSphere Member Manager is the subcomponent of WebSphere Portal Server responsible for accessing the user registries for user and group management and authentication. The user registries may be LDAP servers, a Custom User Registry, or the Member Manager database user registry. WebSphere Process Server (Optional) WebSphere Process Server (WPS) is a business process integration server that is built on top of the WebSphere Application Server. It is built to support solutions created based on service-oriented architecture (SOA). WPS provides services that enable traditional business integration such as enterprise application integration; it also provides services that enable business process automation, such as choreographing business processes as well as human workflows, and management of those business processes. WPS uses the Service Component Architecture programming model and Service Data Object (SDO) data model. SDO business objects can be defined, transformed, routed, and mapped using SCA components. The connectivity to back-end Enterprise Information Systems (EIS) is provided by the resource adapters. In the outbound mode, WPS uses adapter to send data to the EIS system from the integration application. In inbound mode, WPS uses adapters to trigger the integration application by the event occurring in the EIS system. For example, an adapter can be deployed on WPS to synchronize product information across multiple enterprise 18 IBM WebSphere Portal V6 Self Help Guide
