Need of SAP HANA

A typical IT landscape has developed over many years into a complex arrangement with multiple applications developed, purchased and acquired, powered by multiple platforms. The platforms can be based on incompatible hardware from different vendors, with different operating systems and different databases, and even different development languages. In order to try to pull together these different application we added extra applications.
IT have been responsible for the integration of these systems. Moving data, harmonizing, cleaning, resulting in multiple copies of the data. We placed huge demands on system resources during batch processing and expected users to wait for long running processes such as financial close, consolidations, MRP.
Complex landscapes result in fragmented business views of data. In order to obtain a holistic view users are required to wait until consolidation is complete. Developing new applications in a complex landscape is also difficult, it takes time and is expensive to build and maintain.
There is too much IT complexity in most organizations, Complex landscapes are costly to maintain with multiple skills needed.
Complexity is stifling growth and suppresses agility and innovation, which is critical in today’s digital world in order to survive.

The answer is to have all applications powered by one high performance platform. This means only one store for all data regardless of type and a common architecture. Data is available to all applications in real time, no more data movement and no more management of multiple data stores.
A key objective of SAP HANA is to remove all redundancies. This means only one copy of data is needed.
SAP HANA is a platform where it is possible to combine online transaction processing (OLTP) applications with online analytical applications (OLAP). SAP HANA provides a common set of development tools that can be used to create many different types of applications. SAP HANA can be deployed in the cloud or on premise.
