In our experience of working with organizations of all sizes, across verticals and geographies and varying technology maturity levels, we see three categories of SAP HANA implementation:
Many organizations these days prefer customized services but without the headache of maintaining large IT teams. Their strategy combines owning a private cloud, datacenter or hosting of choice, with public cloud options for transient, temporary and dynamic requirements.
Overcoming HANA complexities with the right solution
SAP HANA is a sophisticated application system with its own complexities and requires dedicated manpower and resources for successful implementation and maintenance in order to derive maximized value from investments. SAP HANA implementation projects often see concerns around:

Wipro has developed a comprehensive offering to provide organizations better visibility and control of their complete infrastructure. The offering includes three key components:
Wipro HANA Private Platform as a Service
Wipro partnered with HPE and Intel to create a model of private on-premise HANA Platform as a Service (PPaaS). This offering is ideal for organizations looking for the simplicity of platform-as-a-service mode of consumption along with retaining control of dedicated infrastructure.
Figure 2: Wipro HANA PPaaS - What to expect
The primary asks from HANA clients are lower TCO, operational efficiency and infrastructure agility. Wipro HANA private PaaS architecture blueprint, based on its software defined infrastructure framework – FluidIT, which in turn draws from the strength of HPE infrastructure, Intel Scalable Processor, Optane Persistent Memory and Optane SSD, is designed to address common concerns of SAP HANA enterprises.
Intel’s Optane DC Persistent Memory (Referred as DCPM henceforth) is a new technology that introduces a new flexible tier within the memory / storage hierarchy. DCPM will move larger amount of data closer to the CPU, so it can be accessed, processed, and analyzed in real-time (without first being retrieved from storage). DCPM is comparable to DDR4 DRAM in form factor and performance. They are byte-addressable, like memory, meaning programs can access data structures in-place. This allows for memory like performance with the capacity benefits of NAND.
Additionally, it has data persistence features typically found in NAND SSDs. This means that customers can keep more data, closer to the CPU for faster processing, and that data will remain in memory when the system is power cycled.
The Wipro HANA platform rationalizes and accelerates HANA adoption by building four key capabilities:
1) Elastic capacity
The on-premise, private, and dedicated infrastructure can scale-up, scale-out or scale-down based on business demand. Customers can add capacity incrementally without paying for future capacity requirements. The consumption units are flexibly defined during the design phase to best suit the client’s growth strategy.
FluidIT architecture seamlessly integrates with both public cloud infrastructure and SAP Cloud, enabling clients to leverage the best-fit option. The FluidIT AppAnywhere framework provides a distributed data fabric to enable application movement between cloud and on-premise.

FluidIT is highly automated with programmable architecture based on software defined infrastructure components. Wipro ServiceTheatre automates infrastructure-heavy HANA application tasks and places control directly into the hands of the application team. For instance, the application team can schedule a QA refresh at the click of a button without worrying about the underlying infrastructure tasks associated with it. While the application team is empowered, the IT team is still in full control of the solution and can influence and affect the final outcome based on defined policies and budget.
3) Dynamic resource management
Almost every data center has multiple functionality-based clusters, divisional boundaries, security requirements and different flavors of virtualization. As every cluster is an island of resources, organizations end up with excessive buffer resources to cater to high availability and frequent spikes or future growth. FluidIT enables a data center wide buffer pool of resources integrated at the API level with AIOPS toolset to determine the location of resource crunch, and dynamically allocates resources to respective clusters. It can also pull out resources from an idle cluster, and reallocate it to a busy cluster. This type of dynamic resource management enables huge efficiency gains, doing more with less.
Figure 4: Dynamic use of DR for Non-prod using PMEM
DR DB can remain active and read only all the time without consuming too much DRAM.
FluidIT optimizes HANA sizing with this dynamic resource management. The sizing can be optimized to a great extent with Disaster recovery (DR) or high availability (HA) hardware for non-production usage. DR or HA environment can be configured to accommodate otherwise idle instances, and most of the DRAM can be used by non-production instances. In case of a failover, ServiceTheatre DRM workflow automatically reassigns the resources to active instances, re-optimizing non-production workload.
4) Maximized availability
FluidIT architecture is designed with the key goal of minimizing services downtime, and not just maintaining server uptime. SAP HANA FluidIT reference architecture extensively uses Intel Optane Persistent Memory to reduce HANA startup time by more than 90%. Persistent Memory, as the name suggests, persists across reboot and power recycles, ensuring all the tables are still available in memory during the next system startup with only the Delta fragment needing uploading from the disks. The FluidIT AIOPS toolset proactively monitors system performance and acts autonomously through the ServiceTheatre, in case of system uptime being impacted. For e.g., auto-scaling a load balanced application cluster with additional nodes to take care of additional loads. FluidIT architecture allows for independent patching of different components like operating system, application binaries or hardware firmware. ServiceTheatre leverages this feature to patch systems using snapshots and minimizes downtime on running applications.
Get the full power of SAP HANA with Wipro PPaaS
Wipro PPaaS drives organizations into the future of technology, offering the complete visibility & control of the platform architecture without the responsibility of managing it. Customers can dictate their unique business requirements without getting involved in the technical intricacies of infrastructure and SAP basics. They can leverage the advantage of customized KPIs defined for the SAP platform services, and can consume the platform at their own pace without worrying about capacity planning and procurement. The underlying platform provides API integration with clients’ existing DevOps tool chain or ITSM toolset.
The Wipro offering built around SAP’s next gen HANA platform is a step into the future as it supports key organizational initiatives, helping businesses stay simple, secure, and strong in the digital economy.
