50 WebSphere Application Server V7.0: Concepts, Planning, and Design
Chapter 3. WebSphere Application Server concepts 3 Before you can plan a WebSphere Application Server installation and select a topology, you need to understand some basic structural concepts and elements that make up a WebSphere Application Server runtime environment. This chapter will introduce common WebSphere Application Server concepts in the following sections: ► “WebSphere Application Server concepts” on page 52 ► “Server environments” on page 73 ► “Clusters” on page 81 ► “Runtime processes” on page 88 ► “Using Web servers” on page 89 © Copyright IBM Corp. 2009.
