HANA Overview - 5

How is HANA licensed?

SAP tried to keep licensing simple with HANA.

HANA is available in the Cloud as Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and as an application platform (AaaS), and it is possible to buy all those options now, on a monthly basis, from the SAP Website.

For on-premise customers, HANA is licensed in one of two major ways:

First, is as a proportion of your Software Application value (SAV), just like you can license other databases from SAP. This could be for your whole estate, or for a specific product like BPC.

Second, is by the unit, which is 64GB of RAM. There are a few editions of HANA, depending on your need, that bundle other software and allow more, or less, restrictive usage. The pricing is tiered, depending on the number of units you buy, and accretive.

In all cases, HANA licensing includes a lot of functionality that you would pay extra for in other databases. For example, Dev, Test, HA, DR licensing are always included. And if you buy HANA Enterprise, you have access to all functionality at no additional cost – including Predictive Libraries, Spatial, Graph, OLAP, Integration and Web. HANA contains a huge amount of functionality that would require 20-30 different SKUs from Oracle.

For those customers who need the base functionality of HANA but not the bells and whistles, there is now a HANA Base Edition, on which you can add other functionality as required, at a lower cost point.

Is SAP HANA a database, platform, appliance, or cloud?

SAP HANA was designed to be a truly modern database platform, and as a result the answer is: all of the above. A modern database should be a database, platform and be available on-premise or in the cloud.

SAP has a large installed-base of on premise ERP customers, and the HANA platform supports their needs, especially the need for an enterprise-class database. Many of those customers are looking for an on-premise database to replace the traditional RDBMS.

The demanding needs of an in-memory database mean that SAP elected to sell SAP HANA as an appliance, and it comes pre-packaged by the major hardware vendors as a result.

However the future of business is moving into the cloud, and SAP HANA is available as Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) with HANA Cloud Platform and Managed Cloud as a Service (McaaS) with secured HANA Enterprise Cloud and via 3rd party cloud vendors. Customers can also choose Hybrid deployment model that combines on premise and cloud. More details on this are available here.

How does SAP HANA compare to Oracle or IBM?

SAP HANA was designed to be a replacement to Oracle or IBM databases, either for net new installations or for existing customers. In most cases it is possible to move off those databases easily, and gain reporting performance benefits out of the box. Then it is possible to adapt the software to contain functions that were not possible in the past.

All three of the major RDBMS vendors have released in-memory add-ins to their databases in the last year. All of them support taking an additional copy of data in an in-memory cache, or in IBM’s case columnar tables.  All of them provide improved performance for custom data-marts.  But make no mistake; caching data has been around for a long time, while an in-memory database platform to run transactions and analytics together in the same instance is a new innovation.

Traditional database caching solutions are similar to the GM and Ford response to hybrid cars – take their existing technology and bolt new technology to it. SAP HANA is more akin to Tesla, who rebuilt the car from the ground up based on a new paradigm.

And so HANA’s capabilities from a business application perspective are 3 years ahead in technology from what others have.

What SAP Applications run on SAP HANA?

SAP CEO Bill McDermott said “HANA is attached to everything we have”.

Almost all the major SAP Applications now run on the SAP HANA platform. This includes the SAP Business Suite (ERP, CRM, PLM, SCM) and the SAP BW Data Warehouse.

The BI Suite including BusinessObjects Enterprise, Data Services and SAP Lumira are all designed to run on the HANA platform.

There are a set of Applications Powered by SAP HANA including  SAP Accelerated Trade Promotion Planning, SAP Collection Insight, SAP Convergent Pricing Simulation, SAP Customer Engagement Intelligence, SAP Demand Signal Management, SAP Assurance and Compliance Software, SAP Liquidity Risk Management, SAP Operational Process Intelligence, and SAP Tax Declaration Framework for Brazil.

In addition, SAP runs much of its cloud portfolio on HANA, including the HANA Cloud Platform and SAP Business ByDesign. The Ariba and SuccessFactors apps are in the process of migration.

What’s the business case for SAP HANA?

We’ve built business cases for HANA deployments of all sizes and whilst they vary, there at a few common themes:

• TCO Reduction. In many cases HANA has a lower TCO. It reduces hardware renewal costs, frees up valuable enterprise storage and mainframes and requires much less maintenance
• Complexity to simplicity.  HANA simplifies landscapes by using the same copy of data for multiple applications.  Our implementations have shown that adding additional applications to a HANA dataset are very fast and easy, delivering business benefits quickly.
• Differentiation. HANA’s performance, advanced analytics (Predictive, Geospatial, Text analytics) and simplicity often mean a business process can be changed to be differentiating compared to competitors. Customer scenarios like loyalty management, personalized recommendations and anything where speed or advanced analytics capabilities are differentiating are all candidates.
• Risk Mitigation. Many customers know that in-memory technologies are changing the world and so want to put an application like SAP BW on HANA or LOB Datamarts as a first step, so they can react quickly for future business demands.

Where does SAP HANA come from?

SAP built SAP HANA from the ground up, including research from the Hasso Plattner Institute in Potsdam, the acquisition of the IP from the p*Time database, the TREX search engine, BWA in-memory appliance and MaxDB relational database. It has been extended with intellectual property from the Business Objects and Sybase acquisitions with products like Sybase IQ and Business Objects Data Federator.

Whilst HANA has a legacy and some code from other products, the bulk of the database and platform has been written from the ground up.

What makes SAP HANA fundamentally different?

SAP HANA is different by design. It stores all data in-memory, in columnar format and compressed. Because HANA is so fast, sums, indexes, materialized views and aggregates are not required, and this can reduce the database footprint by 95%. Everything is calculated on-demand, on the fly, in main memory.  This makes it possible for companies to run OLTP and analytics applications on the same instance at the same time, and to allow for any type of real-time, ad hoc queries and analyses.

On top of this SAP built solutions to all the problems of columnar databases, like concurrency (HANA uses MVCC) and row-level insert and update performance (HANA uses various mechanisms like a delta store).

If this wasn’t enough SAP added a bunch of engines inside HANA to provide virtual OLAP functionality, data virtualization, text analysis, search, geospatial, graph (will be available soon) and web. It supports open standards like REST, JSON, ODBO, MDX, ODBC and JDBC. There is as much functionality in there as a whole Oracle or IBM software stack, in one database.

What kinds of use cases does SAP HANA support?

The first HANA deployments were all analytical use cases like Datamarts and Data Warehouses because the benefits are there right out the box. EDWs like SAP BW run like lightening with a simple database swap.

With a transactional application like Finance or Supply Chain, most things run a little better from a simple database swap (SAP claim 50% faster for their own core finance).  The real benefits come when logic from the applications are optimized and pushed down to the database level, from simplification of the apps (SAP is building a simplified version of their Business Suite), or from ancillary benefits like real-time operational reporting, real-time supply chain management or real-time offer management.

Best of all, unlike the other database systems in the market, HANA supports all applications on the same instance of data at the same time.  No more copying, transforming and re-organizing data all over the enterprise to meet the needs of different applications. HANA perfectly serves the needs of all applications with one “system of record” instance.
