Application server :

Part of the application layer of an ABAP-based SAP System.
If the system is distributed to several application
servers, these are usually installed on different computers
whose operating systems do not need to be identical.
However, several application servers of one or more ABAP-
based SAP Systems may run on one computer.

Application servers communicate with the presentation
layer, the database layer, and with each other via the
message server. The most important components of an
application server are its work processes, the number and
type of which are determined when the ABAP-based SAP System
is started. An ABAP program is executed by a suitable
application server work process. The storage areas of an
application server, which can be accessed in the ABAP
programs, are the shared memory, the SAP memory, the ABAP
memory and the roll area in the internal session.
