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
