SAP on Cloud

Cloud computing hasrevolutionized the way IT is delivered. At its core, cloud computing has alwaysbeen about meeting the changing business needs of organizations. Whether it’senabling flexibility, increasing agility, cutting costs, or improvingperformance, organizations can leverage this revolutionary technology toaddress unique business needs and adapt to changing market conditions.

A growing number oforganizations have already migrated or are planning to migrate their businessapplications to the cloud. The most mission-critical among these applicationsare SAP applications. For organizations looking to migrate SAP applications tothe cloud, it is important to have a general understanding of the differentaspects of cloud computing and their relevance to SAP applications. 

Benefits of hosting SAP onCloud? 

Migrating an existing SAP systems& applications to the cloud is a complex and laborious task. Despitethe barriers to adoption, the attractiveness of cloud is on the rise. Here are some key benefits of migrating your SAP applications:

Address unpredictable application demand- Business demand fluctuates. With cloudsystems, organizations can rapidly scale up and scale down resources to meetany kind of demand. 

Fuel growth- The cloud improves business agility, flexibility, and scalability. It also enables service innovations. 

Improve budgeting and bottom-line economics- With your SAP application on the cloud,you only pay for what you consume, the productivity of employees increases, andresource utilization becomes more efficient. 

Public vs. Private vs. Hybrid. What is the difference? 

Cloud services have threedeployment models: public, community and private. A mix of these deploymentmodels is what we call a hybrid strategy. Each deployment model has advantagesand disadvantages. Customer must decide which advantages address their specificneeds and which disadvantages they can live with. 

SAP on Public Cloud 

Public clouds are owned andoperated by third-party service providers that deliver their computingresources over the Internet. Under the public cloud deployment model, allhardware, software, and other supporting infrastructure are owned and managedby the provider. This allows organizations to transition from CAPEX toOPEX. 

Hosting SAP applications on thepublic cloud can offer organizations cost and performance benefits. A majordrawback to this option, however, is security. Companies need to decide whichtype of data can reside in the public cloud and which data must resideinternally for security purposes. 

SAP on Private Cloud 

Private cloud is a deploymentmodel in which computing resources are provisioned over a private ITinfrastructure for the dedicated use of a single organization. In this set up,the responsibility of buying, maintaining, and managing hardware and softwarefalls on the customer. Because of these responsibilities, private cloud doesn’toffer much cost savings. What it offers is an increase in performance andsecurity of the data across the SAP Applications.

The performance of SAPapplications will be higher on private cloud because its infrastructure usesprivate connections, which are faster than the web connections used in publiccloud. In terms of security, private cloud has the edge because it givescustomers more control over security and compliance.  

Why not go Hybrid?

If you can’t choose betweenpublic and private cloud, you can have the best of both worlds by adopting ahybrid approach. A hybrid cloud is a combination of public and private. Itgives organizations the ability to migrate their SAP systems and applicationsto the public cloud and host sensitive data privately on the private cloud. 

The hybrid approach offersgreater business flexibility and helps optimize an organization’s existing SAP infrastructure,security, and compliance. The only drawback is that the hybrid SAP on Cloud modelis the most difficult and complex model to implement. 

 

What to Consider Before a Migration? 

If you plan on moving your SAPlandscape and other parts of your business to the cloud, here are some thingsto consider:

Data security against loss- Whenplanning a backup strategy for your data, always think of the worst-casescenario: a natural disaster, human error, an employee looking for payback,etc. From this vantage point, attempt to understand the disaster recoveryconcept of your potential cloud service provider.

Performance-Ask potential cloudservice providers about service level agreements (SLAs) that guarantee theservice’s performance. 

Availability- Your SAPapplications are critical to your business processes. The SLAs for serviceavailability must be strict. 

Complexity- Because of theinherent complexity of the SAP application, cloud migration will introduce alevel of complexity that you have not dealt with before. When planning your migrationstrategy, speak to experts who have deep technical expertise on the SAPapplication, SAP systems migration and cloud infrastructure.

Legal Requirements- Before amigration, you must know the regulations that protect data in your industry.Certain hospitals running SAP IS/H, for example, are prohibited from storingpatient data off premises. These are the kinds of regulations that you mustthoroughly understand to avoid legal ramifications after a migration.
