Infosys SAP HANA Journey

Posted on behalf of Jitendra Sangharajka D., VP & Senior Delivery Manager, Information Systems

SAP is the core enterprise platform that forms the backbone for all key business areas including Finance, HCM, P2P, Planning & Budgeting and Data Warehousing.

Infosys has nearly two decades of history of having well organized and coordinated set of processes for all the business stakeholders across Finance, HR, Subsidiaries and delivery units. These core processes are hosted across 15+ SAP solutions and in-house developed applications. Our SAP Solutions are deployed on 90+ SAP instances hosted on 150+ servers, 100+TB of storage. 100% of our non-PRD environment is virtualized with innovative front-end virtualization for ASCS (ABAP SAP Central Services) and SCS (SAP Central Services). All our application server instances in production environment are virtualized too.

Over years we had added terabytes of data and challenge was to address exponential growth and landscape complexity. Along with the requirement to add and sustain large data volumes, came the requirement for better, I would say sub-second performance as well. In early 2014 we carried out extensive evaluation of the bleeding edge in-memory columnar database SAP platform - HANA. Over 10 months we conceptualized, designed and migrated to HANA (SoH), Business Warehouse (BW), Business Planning and Consolidation (BPC) and Supplier Management system (SRM) to HANA DB. The landscape setup comprised 8 HANA appliances across three data centers, migrating more than 10 TB of database to HANA. We were able to save DB footprint by 35%.  We carried out multiple mocks before go-live to ensure no impact to business and project timelines. We also adopted the concept of parallel project landscape to ensure BAU is not impacted. The HANA platform was designed to ensure ZERO RPO with synchronous replication between Primary and similar appliance on near DR site.

HANA transformed our SAP landscape and proved instrumental in helping our critical business functions, mainly Finance to accelerate critical cycles like Year-End, Quarter-End and Month-End processing. BW on HANA has added real-time analytics capabilities. UI5 and SAP Fiori helped us re-image user experience.

Once HANA was operational, we innovatively leveraged HANA platform for installing application servers on HANA, migrated non-ERP databases to HANA and adopted MCOS for hosting non-production databases.

Our HANA deployment is the world's largest single instance of SAP Business Suite powered by SAP HANA on Hitachi Unified Compute Platform (6TB RAM).  Hitachi being our trusted partner for more than 15 years, was chosen as supplier for HANA appliances due to its unique advantage of availability of 6 TB appliance on latest and SAP approved architecture within our project timelines with support for conversion of scale-up to scale-out, logical partitioning, TDI and simplified backup model.

It is heartening to note that 194000+ global user base and business teams that manage this US$ 9.5 Billion enterprise, tens of millions of square feet of real estate and tens of thousands of projects trust our Platform.

On behalf of Infosys, I welcome you to join our joint session with Hitachi at SAPPHIRE NOW. Please attend the session and hear our deployment details, realized business benefits and the roadmap to SAP S/4HANA suite.
