Definition: Application Server ABB is a Technology Service that implements the behaviour of system software that resides between the operating system (OS) on one side, the external resources (such as a database management system [DBMS], communications and Internet services) on another side and the users’ applications on the third side.

This exposition of application contributes to the integration of legacy systems and siloed information to expose to the different public service consumers.
