Good or bad idea?
The core concept of SAP HANA Extended Application Services is to embed a full featured application server, web server, and development environment within the SAP HANA appliance itself. However this isn’t just another piece of software installed on the same hardware as SAP HANA; instead SAP has decided to truly integrate this new application services functionality directly into the deepest parts of the SAP HANA database itself, giving it an opportunity for performance and access to SAP HANA differentiating features that no other application server has.
