Application server-based enterprise applications
Application servers provide services required to allow for users to access applications and data over the Internet. But what are the components of such servers, and who provides these components. This tip, excerpted from

Application services help alleviate some of the infrastructure coding that would otherwise be embedded within the standalone enterprise application. An application server architecture includes the primary elements that comprise a functioning enterprise application serving environment.
These are the primary application server elements:
- Enterprise application component--The enterprise application component encapsulates the business logic and data of an enterprise application.
- Enterprise application module--The enterprise application module contains one or more enterprise application components to form an individual enterprise service. Enterprise application modules also contain a module deployment descriptor for defining the configuration and deployment properties of the module.
- Enterprise application--The enterprise application represents a cohesive collection of enterprise application modules, as well as perhaps Web application modules. Additionally, an enterprise application deployment descriptor contains any enterprise application assembly information.
- Enterprise application container--The enterprise application container provides the runtime environment in which enterprise applications operate.
- Enterprise application server--The enterprise application server provides the systems infrastructure functionality, such as enterprise communication services (for example, CORBA object request brokers), transaction-management services, security, and services in an integrated application server environment.
