About The Client

The customer is a large retail enterprise operating multiple business units, each running mission-critical SAP ERP workloads across AWS and on-premises environments. These systems support core retail functions, including finance, supply chain management, inventory management, and business operations.

Business Challenges

With 4–5 independent business units, the customer managed separate SAP landscapes, AWS accounts, and supporting infrastructure. This led to:

• High operational overhead and fragmented SAP operations.
• Inconsistent monitoring, patching, and incident response.
• Security risks, including public IP exposure on SAP systems.
• Limited compliance visibility and governance.
• Rising cloud costs due to duplicated SAP Routers and Dispatcher servers.
• Increased downtime impacting business continuity.

The customer needed a trusted AWS Managed Services Partner to take ownership of day-to-day SAP operations, strengthen security, improve availability, and optimize cloud costs.

Business Solution

After onboarding the customer to NuSummit’s AWS Managed Services, we assumed end-to-end responsibility for operating and optimizing their SAP workloads on AWS.

Key managed services delivered:

• 24×7 Monitoring and Incident Management for SAP HANA, SAP Application Servers, EC2, and supporting AWS services.
• Proactive Operations, including patching, backup verification, performance tuning, and capacity management.
• Integrated ITSM and Alerting, enabling automated ticket creation and rapid response
• Security Operations and Continuous Compliance, including CSPM, centralized logging, and regular security assessments.
• Cost Optimization as a Continuous Service, through rightsizing and elimination of duplicated SAP components.

To simplify ongoing operations, NuSummit also introduced standardized governance and centralized management for SAP Router and Dispatcher servers, improving operational consistency across business units.
