SAP has also certified cloud infrastructure providers to host SAP HANA applications along with their own cloud offering.
SAP HANA deployment options and the considerations to know the right one
Organizations today have multiple hosting options for their SAP HANA applications as well as different architectural constructs to achieve performance, scalability, availability, disaster recovery, customization and cost optimization. Here’s a quick peek at some of the most popular deployment options and their key considerations:
SAP Cloud: This is a Software-as-a-Service (SAAS) offering from SAP, with two variants - Essentials and Extended editions. The Essentials edition supports only greenfield implementation. The Extended edition allows greater flexibility and functionality, with shared infrastructure and platform across multiple customers. The degree of flexibility is however limited in cloud editions. The Extended edition also allows selective data transition. There is no need to invest in software licenses and customers can simply subscribe to SAP Cloud and start using it. These offerings are mostly opted for when the need for customization and concern on shared infrastructure is low.
SAP HEC: SAP HANA Enterprise Cloud is a full functionality software with dedicated infrastructure hosted in the SAP service providers’ data center but fully managed by SAP. SAP has partnered with multiple providers across geographies to provide and manage the infrastructure. While SAP provides technical application managed services, SAP application support is provided by the chosen SAP partners. The default SLA is 99.5% up-time with upgrades at extra cost. The SAP licenses are owned by the customers, but there are limitations on the extent of customization supported. Infrastructure flexibility is low as compared to the cloud with minimal catalog options.
HEC is mostly opted for by customers who want privacy of infrastructure with outsourced management of the SAP platform.
Public cloud IaaS: This is similar to on-premise SAP implementation and operation but the underlying infrastructure is owned by hyper-scalers who offer virtual machines on shared infrastructure or dedicated bare metal instances. Customers own their SAP licenses and manage everything – from the operating systems to applications. Clients with a dynamic requirement of infrastructure, typically in the midst of a long project, usually prefer this option. Non-production on public cloud in steady state operations is another common use case. However, organizations with high infrastructure and performance requirements, steady usage, and latency sensitive business operations with strict regulations and compliance requirements usually shy away from hosting their SAP application on public cloud infrastructure.
SAP on-premise: This is the most leveraged option by SAP customers. These organizations generally have large IT teams of their own or they outsource infrastructure and/or application management to professional companies, while retaining control of technology. With mission-critical and strategic data, they have high sensitivity to latency. These organizations also face typical challenges of technology obsolescence, platform lifecycle maintenance, talent recruitment and retention, and most importantly, maintaining operational efficiency. IT infrastructure needs to be overprovisioned to avoid long procurement delays. A high degree of success is dependent upon their infrastructure and the application partners’ capability.
Hybrid option: Large organizations who want to retain mission-critical application infrastructure within the safe confines of their datacenter or private dedicated hosting spaces are on the lookout for contextualized and curated services with on-demand availability of infrastructure. Opting for a hybrid platform provides them the ease of starting a new project with unpredictable and dynamic resource demand in public cloud and then shifting it back to private cloud once resource consumption gets steady.
The HANA journey toward transformation
SAP HANA helps simplify the IT landscape and reduce data management burdens for organizations with their enterprise-proven database platforms. However, as organizations embrace digitization at scale and harness their data to understand their business and customer needs better, the need for efficiency and scale of processing will increase, driving improvements in existing ERP systems.
With the experience of implementing and supporting multiple modes of SAP application hosting for our customers, Wipro has partnered with HPE and Intel to create the next-gen model of a private on-premise HANA Platform as a Service offering.
