Many people must now know about the various deployment options available for HANA. Here I am trying to summarize few options based on my HANA experience which I got while doing the implementation/migration and upgrade project on HANA. In this blog, users will be able to analyze and decide what deployment option to choose for the HANA implementation and what all are the benefits/limitation with different deployment options.

1. SAP HANA Deployment Options

 

SAP has started its HANA journey nearly 4 years back and now everyone is aware of what is HANA, how it helps to improve the business and helps with speed for your analytical and transactional processing.

Still many times it’s confusing and lots of customers are still not able to understand the HANA deployment options, what all are the pros and cons with different deployment options and how to choose one.

Here today we will discuss about the different HANA deployment options and what are different scenarios/use cases for HANA deployment.

First let’s start with the HANA deployment options, below diagram will show you the deployment overview for HANA.

  • On Premise
    • New HW Appliance
    • TDI – Tailored data center integration

 

  • Cloud
    • AWS Cloud
    • Various cloud hosting partners
    • SAP Cloud
      • SAP HANA HCP – HANA Cloud Platform (PaaS – Platform as a service)
      • SAP HANA HEC – HANA Enterprise Cloud (IaaS – Infrastructure as a service)

2 On Premise Deployment


2.1 Appliance Model -


SAP started HANA deployment with the appliance model by partnering with various HW vendors. With the appliance model it was fully developed and supported HANA implementation by SAP and it had fastest deployment cycle. Once the customers approved the BOM the HW vendor will start the certified HANA appliance shipment.


The benefits of appliance model was,

  • Certified and validated solution by SAP and HW partners
  • Pre-configured HW setup as per the HANA requirements
  • SAP HANA installation done by HW partners with the specified and recommended guidelines from SAP

The appliance model was very expensive due to which the HANA adaptation was done by very few customers.

    

2.2 TDI – Tailored Data center Integration

In order to increase the HANA adaptation and its footprint SAP started looking for TDI – Tailored data center integration approach.

 

TDI has definitely helped various customers who were looking for HANA implementation because of its more flexibility and it helped save the IT budget and the existing investment which enterprises did for their IT investments.

SAP started rolling out TDI with the enablement of storage/persistent layer so that most of the customers can utilize their enterprise storage investment and adapt HANA.

Definitely there are restrictions to go for TDI model and restrictions because SAP wants to make sure the companies who are going thru TDI model should achieve the maximum result for their investment.

The benefits which you get from the TDI model,

  • The overall operations cost and hardware cost is reduced as you will be utilizing the existing enterprise storage
  • Reduced risk and optimized timelines as the overall responsibility lies with the existing in house experts
  • Lots of flexibility for hardware selection and negotiate the cost for HANA investment

The limitations of TDI Model,

  • Installation by SAP certified consultant and validation needs to be done by customer
  • Support model needs to be aligned with HW partners and customers needs to take care that
  • For TDI model, customers should go for the certified servers and certified storage partners

With Appliance and TDI model lots of HW vendors who are supporting HANA can be choose from. There are lots of combinations to choose from which give benefits varying from performance, cost, scalability etc.

3 Cloud Deployment

SAP HANA cloud deployment has been matured over the time and there are various options available now for the HANA cloud deployment. SAP enabled cloud deployment with the introduction of AWS – Amazon cloud back in 2012.


3.1 AWS – Amazon Web Services

With the enablement of AWS cloud of HANA deployment, SAP initially started AWS cloud for HANA with 2 options.

  1. 1. SAP HANA Infrastructure Services
  2. 2. SAP HANA One
  3. 3. Developer edition
  4. 4. SAP HANA trial systems

Figure 4: SAP HANA AWS Architecture

 

The benefits of adopting AWS cloud for HANA implementation is,

  • Achieve faster time to value for your SAP HANA project with the AWS on-demand infrastructure.

Seamlessly integrate your SAP HANA system running in your Amazon Virtual Private Cloud (VPC) with your existing on-premises systems.

  • Scale resources up or down as necessary. Pay only for the infrastructure resources that you need and use.
  • Run SAP HANA workloads like SAP Business Warehouse (BW) or other OLAP scenarios on a multi-node cluster, providing up to 4 TB of memory.
  • Develop and deploy SAP HANA quickly and reliably in the cloud, and leverage your existing licensing investment with no additional licensing fees.

The limitations with AWS HANA cloud infrastructure is,

  • AWS has limited memory VMs which limits the implementation of large scape HANA environment
  • The business suite on HANA implementations are not done on AWS HANA cloud
  • HANA scale up scenarios are not supported on AWS cloud
  • Advisable for small businesses

3.2 Cloud Hosting Partners


Various data center hosting providers are now having SAP certification for hosting the SAP HANA infrastructure on their cloud environment.

SAP and cloud providers are working aggressively to provide customers with the lowest total cost of ownership experience for their applications powered by SAP HANA.

Hosting partners are rapidly achieving certification for their SAP HANA Cloud and SAP HANA Enterprise Cloud solutions to give companies multiple choices in next-generation mission-critical cloud infrastructures.

The benefits of adopting the cloud infrastructure from cloud providers are,

  • Highly customizes solutions as per business needs
  • Hybrid cloud setup with integration with in-premise as well as 3rd party applications
  • SAP certification for HANA implementations
  • Less TCO

Various partners working with SAP to make their cloud services optimal to support the HANA implementations, so that the customer can get maximum benefits for their investments.

 

Few hosting partners who provides HANA cloud services,

  • SUNGARD Availability Services
  • Virtustream
  • Hitachi/Oxya Cloud Solutions

 

3.3 SAP Cloud


3.3.1 HCP - SAP HANA Cloud Platform (PaaS – Platform as a Service)

SAP HANA Cloud platform is a service developed by SAP under platform as a service category, as part of this SAP allows customers and partners to extend their existing applications and develop new applications to deliver new capabilities.

The benefit of HCP is, it’s open, standards based platform that helps to connect with any of the SAP systems. It can connect any of the business suits of applications, SuccessFactors application and any cloud environment

With HCP, SAP says, is that it offers integration services between the on premise and cloud worlds—the so-called hybrid IT landscape.


3.3.2 HEC - SAP HANA Enterprise Cloud (IaaS – Infrastructure as  a Service)

SAP HEC is the infrastructure services provided by SAP on their datacenters. With this service, SAP is offering to offload all the SAP maintenance services and helping client focus more on their business.

SAP has developed robust framework to handle the HEC services, it starts with the assessment services conducted by SAP which follows the onboarding and migration of customer’s applications onto the cloud infrastructure.

After which the ongoing maintenance and support starts which is taken care by SAP.

HEC includes all the regular maintenance services such as application backups, patching, provisioning and upgrades, restore and recovery and infrastructure monitor and event detection.

This is completely private cloud infrastructure setup for the customers

The existing SAP licenses can be brought in or customers can adopt the subscription based license based on their usage.

The key benefits of SAP HEC are,

  • Complete managed service which includes infrastructure, deployment and management of the SAP applications
  • Customers can benefits from the deep expertise from SAP to manage their complete landscape
  • It helps in reducing the IT management cost (moving from OPEX to CAPEX model)
  • Customers don’t have to worry about the system upgrades and any new patch implementation. SAP application management team takes care all these aspects with the minimum business downtime/disruption.
