WAS implements J2EE specification
WebSphere Application Server provides the environment to run your Web-enabled
e-business applications. An application server functions as Web middleware
or a middle tier in a three-tier e-business environment. The first tier is
the HTTP server that handles requests from the browser client. The third tier
is the business database (for example, DB2 UDB for iSeries) and the business logic
(for example, traditional business applications, such as order processing). The
middle tier is WebSphere Application Server, which provides a framework for a
consistent and architected link between the HTTP requests and the business data
and logic.
With the Base and Express packages, you are limited to single
application server environments. The Network Deployment package allows you to
extend this environment to include multiple application servers that are
administered from a single point of control and can be clustered to provide
scalability and high availability environments.
