SAP Transformation to Cloud Case Study

Challenge

Highlights:
  • Reduced System availability due to unplanned downtimes and lack of highly available infrastructure

  • Longer system provisioning and system refresh times

  • High operations cost

  • No protection against disasters

The client is a Global Medical Device company and leader in new product development and medical education in orthopedics. With a corporate mission of helping surgeons treat their patients better, the client has pioneered the field of arthroscopy and developed more than 11,000 innovative products and surgical procedures to advance minimally invasive orthopedics worldwide.

The client continues to experience unprecedented growth and demand for their products throughout the world; However, as a fast-growing company running SAP for their critical business, they faced constant challenges from their outsourced provider with the provisioning of new SAP landscapes and in supporting various business initiatives within the company.

Their SAP landscape consists of ECC, BW, CRM, TREX, Portal, PI, GRC, Vertex, Paymetric, GTS, Adobe, ATS, Fiori, QIM, Biller Direct, TDMS, SLD and Solution Manager running on a Windows/SQL platform in Europe (Outsourced Data centers). In 2015, as their business velocity accelerated (500-600% increase in sales), The client began searching for a more cost-effective, dynamically scalable, and reliable way to run their production SAP landscapes and other applications on a 24x7x365 with 99.9 availability.

While maintaining data centers across Europe for their SAP platform and USA for the Non-SAP platform, which they had virtualized using VMware software, the customer faced several challenges.

The major challenges were as follows:

  • Unplanned downtime for their 24×7 SAP Landscape

  • Longer New Server Provisioning time – 2 weeks

  • Longer SAP Systems Refresh / Copy time – 1 week (appx)

  • Lack of High Availability

  • No Disaster Recovery Plan

  • Overall High Cost for running SAP Infrastructure

Moreover, the outsourced hosting vendor did not provide any insights or transparency of their SAP landscape infrastructure and lacked flexibility in deploying and managing the SAP infrastructure. The SAP recovery time during planned or unplanned outage caused prolonged business interruption.

The client did not want to continue making investments in maintaining data centers, server farms and infrastructure technicians and began considering Cloud as a potential alternative. They also wanted to find a more agile way to deliver IT by outsourcing SAP Basis and Cloud Infrastructure.

They decided to conduct an RFP process called eTTraP (ERP Technical Transformation Program) and Wharfedale Technologies (http://www.wftcloud.com) was chosen to provide SAP Migration and Modernization along with 24×7 managed services.

Solution

Highlights:
  • Highly available (99.9%) and disaster protected SAP landscape in cloud

  • Minimal downtime SAP heterogeneous migration to cloud

  • Proactive end to end support including infrastructure and SAP applications.

  • No upfront costs to customer

Wharfedale is a strategic Gold Partner with Microsoft specializing in migrating and running SAP Workload on Azure. Wharfedale works closely with Microsoft Azure Engineering team to optimize SAP and HANA workloads on Azure.

Wharfedale presented an end-to-end solution to the client which included evaluating their existing SAP landscapes running on their outsourced provider in Europe. A feasibility study was performed to migrate their SAP landscape to Azure seamlessly with minimal impact to the business. Wharfedale is among the first to implement SAP Production and Non-Production (220+ Servers) on Public Cloud.

Wharfedale’s 74 factor SAP transformation methodology helped the client land their SAP landscape into Microsoft Azure Cloud in Europe. This allowed the client to be compliant with Safe Harbor (EU-US Privacy Shield) policy by keeping their data in Europe. The solution also includes having their Disaster Recovery site in Europe to maintain compliance.

Our unique experience and 74 factor methodology helped the client save considerable licensing costs using Hybrid Use Benefit (EA / HUB Licensing). In addition, this helped the client migrate their SAP landscape from their outsourced provider to Azure without incurring additional licensing costs.

To implement SAP High Availability by protecting SPOF (Single Point of Failure) with Enqueue Replication is a complex process. Performing this on Cloud is even more complex since there are no shared storage devices. Wharfedale’s extensive expertise in cloud design with High Availability provides 99.9% availability
and protects the client SAP Single Point of Failure with their Enqueue Replication services. Wharfedale maintained synchronous replication within the storage devices between primary and secondary nodes to provide 99.9% availability within cloud for SAP Production and critical systems in the landscape.

Wharfedale’s SAP Cloud Dashboard provides insights and visibility to the customer with real time cost and KPI’s. The dashboard also provides predictive analytics for landscape replication or cost optimization. Using Azure Cloud Elasticity, Wharfedale is able to handle the dynamic growth of the client’s business needs and provides the flexibility to bring idle systems down during off hours to save cost.

The client’s business demands constant refresh on their SAP non-prod systems with production data. Wharfedale’s SCIF (SAP Cloud Image Factory) methodology helped the client get new servers provisioned instantaneously in Cloud and enabling the process to be reduced from weeks to hours.

The client wanted to move their SAP ECC and BW systems to HANA database as part of this transformation program. Wharfedale helped size HANA servers according to SAP HANA TDI (Tailored Data Center
Integration) standards within Azure and used DMO (Database Migration Option) process to migrate their SAP to HANA. Wharfedale followed SAP best practices to perform Mock Runs, Impact Analysis, Code Remediation, ABAP Changes and finally migration to HANA.

Wharfedale also created a Disaster Recovery solution for the client between West Europe and North Europe using both Azure Site Recovery Services and HANA Replication Services to support 2-hour RTO and 5-minute RTO requirements with fully automated failover and failback capability.
