SAP HANA ON CLOUD


Introduction to HANA

HANA refers to High Performance Analytic Appliance. HANA is a database model which is made to work in the memory termed as in-memory database.

SAP Replicated Enqueue with High Availability

A typical high availability solution in a SAP environment does not address the failure of the enqueue service. Leveraging the firm's deep expertise in the SAP application and the associated infrastructure components, the SAP Replicated Enqueue with High Availability solution facilitates the elimination of single points of failure in a SAP environment at the operating system, storage, network, database and application level, thereby minimizing downtime in the customer's environment. This solution enables seamless failover of the enqueue service along with the rest of the components to achieve true high availability in the SAP landscape.

SAP Integration with VCS, MC Service Guard and HACMP

High Availability within an SAP or Oracle landscape is a requirement. WFT's SAP High availability solution addresses the different Single Points of Failure within a SAP Landscape like the Message server, Enqueue server and Web dispatcher. WFT solutions also integrate DB and Infrastructure tools to provide application availability as defined by your company's SLA's. Our engineers look to employ all available technologies including SAP Replicated En-Queue, Oracle RAC and server clustering to achieve high availability.

  • SAP HANA is SAP AG's implementation of in-memory database technology.
  • HANA DB take advantage of the low cost of main memory (RAM), data processing abilities of multi-core processors and the fast data access of solid state drives relative to traditional hard drives to deliver better performance of analytical and transactional applications.
  • HANA is 100% ACID complaint

SAP HANA ON CLOUD Platform is a next generation cloud platform which based on breakthrough in-memory technology as delivered by SAP. This gives Developers where they can quickly build, highly scalable applications that leverage embedded as well as high speed and scale of SAP HANA. The apps will deliver good experiences which includes instant mobile access that delight users and meet the business requirements.

Most of them know SAP HANA is more than just an in-memory database, but it's a complete application development platform .Three distinct Scenarios SAP HANA on CLOUD platform offers .SAP HANA on CLOUD Platform is a Platform as a Service offering(PaaS)

  • SAP HANA App Services
  • SAP HANA DB Services
  • SAP HANA infrastructure services

SAP HANA App Services (Paas)

This includes all the capabilities for Database Service and in addition it provides shared Application Services basically required for development of existing solutions as it resides either will be on-premise or in cloud. The rapid development of cloud application this platform provides a vast set of different platform services for most common in Software architecture such as persistence, connectivity

SAP HANA on CLOUD technology provides specialized capabilities:

Mobile: SAP Mobile Platform Enterprise Edition cloud version

  • SAP HANA Cloud Integration

SAP HANA DB Services (DBaaS)

This provides both infrastructure and license subscriptions for SAP HANA as it offers two offer

A base and Platform Edition. The Base edition includes core DB services, development services and libraries while the platform edition also includes advanced features such as predictive, search, graph, text analysis and geo-spatial

The above two editions provides native development capabilities eg as SQL Script, XS(Extended Application Services (xs)) and River. There is ETL-Tool is preconfigured and ready to used for initial and delta loads.

SAP HANA DB Services allows fast deployment operational flexibility and faster time -to-time market to develop and deploy uses cases that require up to 1 TB Memory.

1Tb of memory is the largest memory configuration available for SAP HANADB services .However actual available memory may be less than the configured memory due to overhead.

Available Editions in SAP HANA DB Services:

SAP HANA Infrastructure Services (IaaS)

SAP HANA Infrastructure Services provides subscriptions for those customers who already has their existing license and those who want to get up and running quickly without investing in hardware.

IaaS Features provide
  • One of the best flexibility deployment options: 128GB, 256GB, 512GB, and 1TB and available on exclusively HANA marketplace.
  • Build on a secure, scalable infrastructure.
  • Certified operations
  • Advance Network Security
  • World class Data Centers
  • Built in Compliance ,Integrity and confidentiality
  • Reliable Data backup

Highlights of HANA

  • Real time decision
  • TCO reduction
  • Next generation Technologies

Major industries lack at the analytics capability required to extract information from various organizations and load that data into action.

Hana in-memory will provide the speed and agility to power analytics at performance levels while remaining cost effective.
