Application hosts are the physical machines on which one or more Sterling Selling and Fulfillment Foundation server processes are run. The application servers must constantly be running to give all client users access to the Application Console and Applications Manager.
The physical machine that runs the application server(s) is known as the host.
Application servers are the processes that handle requests from various places to provide the real-time access to the features and application logic within Sterling Selling and Fulfillment Foundation Sterling Application Platform. The most common type of requests that an application server handles are the requests originating from clients using the Application Console. The application servers are always deployed using an industrial-strength server application such as Oracle WebLogic.
It is important to ensure that the application servers are constantly running and are performing well to ensure all requests are being fulfilled quickly. If the servers are not running properly, the application slows down, and the users of the Application Console find it very difficult to perform their tasks. Multiple application server processes can be run (on the same or different host machines) if the volume of requests is high. It is important to run the right number of application servers based on the volume of requests in your installation.
