Next, SAP began developing SAP HANA-based accelerators, which were deployed as side-carengines to run alongside traditional SAP ERP functions that were critical to businesses,yet were performing slowly. In simple terms, SAP HANA became a secondary helper database and stepped in to help out with the heavy processing.Around the same time,SAP developed new,innovative applications that were completelypowered by SAP HANA and needed massive processing power,such as Smart Meter Analytics and SAP HANA On colyzer.Around 2012, SAP successfully converted its first major application,SAP BusinessWarehouse (BW),to run completely on SAP HANA. This was quickly followed up with theconversion of SAP Business Suite. These existing applications are referred to as powered by SAP HANA, or simply on HANA: for example, Suite on HANA and BW on HANA. Ensure not to confuse Suite on HANA with SAP S/4HANA, as these are not the same. Conversion means the code has been adjusted to work with SAP HANA and also to take advantage of some basic optimizations.
