IBM WebSphere refers to a brand of software products, although the term also popularly refers to one specific product: IBM WebSphere Application Server (WAS). WebSphere is designed to set up, operate and integrate electronic business applications across multiple computing platforms, using Java-based Web technologies. It includes both the run-time components and the tools to develop applications, that will run on WAS.
In other words,
- WebSphere is a set of Java-based tools from IBM that allows customers to create and manage sophisticated business Web sites. The central WebSphere tool is the WebSphere Application Server (WAS), an application server that a customer can use to connect Web site users with Java applications or servlets. Servlets are Java programs that run on the server rather than on the user's computer as Java applets do. Servlets can be developed to replace traditional common gateway interface (CGI) scripts, usually written in C or Practical Extraction and Reporting Language, and run much faster because all user requests run in the same process space.
