An application is similar to Process resource, but it is more flexible and can be managed by batch script which contains multiple processes.
The reason why program is executed using batch script is because it will make it possible managed by MCCS even when the name of starting program and running program is not the same. Besides this, it not only monitors the existence of process but also monitors the response of process with this.
For these reasons, batch script will provide more detail monitoring and flexibility and an application agent manages this.
Same as process, application is basically executed with the system account, but is can be executed with particular user by using attributes of User.
