An application manager (app manager) is programming for overseeing the installation, patching and updating and perhaps access of software applications.
An application manager can be used to monitor a software application's performance and alert administrators if there is a problem. Some application managers for enterprise IT also provide context-aware network access control. In such a scenario, if a device fails to comply with the app manager's security policies, the device is refused access to applications.
Application management is related to application lifecycle management, which involves the tracking of different software versions.
