SAP SE develops and markets an in-memory, column-oriented, relational database management system called SAP HANA which has a core function of working as a database server that retrieves and stores the information that a business application requires. It has an application server and also contains a wide range of ETL capabilities. The configuration and working of SAP HANA can be achieved by viewing a SAP HANA Tutorial. HANA also offers advanced analysis which includes predictive analytics, spatial data processing, text analytics, text search, streaming analytics, and graph data processing. The HANA enterprise cloud solution which is developed by SAP is currently considered as a cloud company which is powered by HANA.
The HANA Distribution on Cloud
HANA is deployed on the cloud by keeping in mind a series of different scenarios.
Public cloud setup-
A public cloud setup is typically managed by the vendor. The computing infrastructure is maintained by the vendor in his premises and the customer’s data is stored in the data centre of the vendor. The customer does not have permission to access or demand visibility of the computing infrastructure which is shared amongst various customers. The cloud vendor is in complete control of the public cloud setup and the customer does not exercise any control over the setup. The modifications, developments, patches, and updates in the software are automatically pushed into the system by the cloud service provider.
Private cloud setup-
The computing infrastructure is present within the premises of the company and all the communication across all the branch offices is facilitated by the company’s intranet. Another option is to host the data at an external data centre but the information is protected by various layers of a firewall. These clouds provide maximum security and control and the system is exclusive to the company whether it is managed by internal or third-party organizations. Companies can also opt for a private cloud setup where they come to a consensus with the cloud vendor regarding the updates and modifications in the software, although control is exercised by the cloud vendor. The provision allows customers to customize their software and make minor modifications when updates appear. SAP has planned to include S4HANA in the private mode of cloud computing.
Customers who wish to keep the infrastructure on-premise are still supported by SAP, which is actually the traditional model of SAP where the customer is responsible for maintenance and modification of software services. This allows the customer to extend their customization to suit the business needs and provides the customer with immense liberty and privacy. The application can be updated by carrying out a meticulous project plan that builds their company rather than giving it a new start.
The public and private clouds are remunerative for-
- The rise of mid-segment SAP implementations where there are wider options to adopt standard SAP packages with best practices.
- A business scenario which is less complex where the business is open for small changes and adopts the standard features.
- A less invasive interference to non-SAP products which may have high bandwidth requirements.
4. Ad-hoc requirements which add to their existing landscape and an existing customer where the existing system needs to be renewed.
