An application server is computer software which provides the business logic for an application program. It offers services such as management of large distributed systems, data services, load balancing, transaction support, and network security. The application server is one part of a three-tier application, consisting of a graphical interface server, an application (business logic) server, and a database / transaction server.
There are good reasons to deploy an application server in a corporate environment. At a high level, an application server enables updates and upgrades to applications to be distributed to all users. System administrators also benefit from the fact that changes to application configuration can take place centrally, which greatly simplifies technical support and ultimately the end user experience. Application servers also simplify user management, avoiding the need to set up and maintain user-management systems for applications. This type of software also enhances scalability and resource usage, and exposes business components via different deployment wrappers.
