Transforming SAP Operations with AWS Managed Services
___Enterprise SAP Migration Success
_____About the Customer…
Mezzan Holding operate complex SAP landscapes spanning legacy ECC 6.0 and modern S/4HANA 2022 environments.
- Cloudwrxs delivers 24/7 managed services across both, achieving 99.9% availability and reducing critical incidents by 40% through expert SAP migration services.
Our team provides end-to-end SAP managed services that combine proactive monitoring, SAP Basis administration, and AWS-native automation to keep mission-critical systems running at peak performance.
Business__ Challenges.
The organisation faced growing operational risk from complex hybrid SAP landscapes that combined on-premises legacy systems with cloud-hosted workloads. Without dedicated SAP operations expertise, the environments were vulnerable to unplanned downtime, integration failures, and escalating costs.
Key issues included the following:
Complex Hybrid Landscape
A mix of on-premises SAP ECC 6.0 and AWS-hosted S/4HANA 2022 created operational silos, inconsistent patching schedules, and fragmented monitoring across environments.
Limited Internal SAP Expertise
The organisation did not have a dedicated SAP Basis team capable of managing the full stack — from database administration through to application-layer tuning and transport management.
High Downtime Risk
Legacy infrastructure running IBM DB2 and Microsoft SQL Server lacked high availability configurations, leaving critical business processes exposed to single points of failure.
Third-Party Integration Challenges
Mezzan’s SAP ECC environment interfaced with multiple third-party applications, with no centralised monitoring of integration health or data flow.
Absence of Proactive Monitoring
Reactive break-fix support meant issues were only addressed after business impact had occurred, resulting in extended outages and lost productivity.
Uncontrolled Infrastructure Costs
Without right-sizing analysis or reserved capacity planning, there was a culture of “buy more hardware” rather than optimizing the estate.
Left unaddressed, these challenges would have continued to drive unplanned downtime, data integrity risks, and escalating operational costs — ultimately threatening the stability of mission-critical SAP processes across the organisation.
Implementation ___Approach.
Conducted a thorough review of both SAP landscapes, cataloguing system versions, interfaces, backup configurations, and existing SLA gaps to establish the managed services baseline.
Onboarded both SAP environments into the Cloudwrxs managed services framework, including knowledge transfer, runbook creation, and ITIL-aligned process definition.
Deployed Amazon CloudWatch dashboards and custom SAP-aware alerting covering infrastructure metrics, SAP application health, database performance, and batch job status across all systems.
Automated routine Basis operations including transport management, user administration, system refreshes, and kernel patching using AWS Systems Manager and scheduled maintenance windows.
Established end-to-end monitoring for all third-party application interfaces on AWS, with automated alerting on data flow interruptions, API failures, and message queue backlogs.
Implemented AWS Backup policies with cross-region replication for disaster recovery, validated restore procedures, and established RPO/RTO targets aligned to business criticality.
Established monthly service reviews with both customers, tracking KPIs against SLAs, identifying cost optimisation opportunities, and implementing performance tuning recommendations.
Our__Solution.
Cloudwrxs delivered end-to-end AWS Managed Services for SAP workloads, combining deep SAP Basis expertise with AWS-native tooling to provide a fully managed, SLA-driven support model across both customer environments.
How AWS Services were used:
24/7 SAP Monitoring
Round-the-clock monitoring of SAP ECC and S/4HANA environments using Amazon CloudWatch, AWS Systems Manager for SAP, and custom application-level health checks to detect issues before business impact.
Proactive Incident Management
ITIL-aligned incident and problem management with defined severity levels, escalation paths, and root cause analysis — reducing mean time to resolution and preventing recurring failures.
SAP Basis Administration
Full SAP Basis support including kernel updates, support pack application, transport management, user administration, and performance tuning across both ECC 6.0 and S/4HANA 2022 systems.
Integration Monitoring
Continuous monitoring of all third-party application interfaces hosted on AWS, with automated alerting on data flow failures, API timeouts, and message processing errors.
Backup and Disaster Recovery
Comprehensive backup strategy using AWS Backup with cross-region replication, automated restore testing, and documented DR runbooks aligned to agreed RPO and RTO targets.
Cost Optimisation
Ongoing right-sizing of Amazon EC2 instances and Amazon EBS volumes, implementation of Reserved Instances and Savings Plans, and storage lifecycle policies — delivering 20–25% infrastructure cost savings.
Measurable__Outcomes.
Within the first six months of managed services engagement, the organisation achieved significant improvements in system reliability, operational efficiency, and cost control across their SAP environments.
99.9% System Availability
Achieved 99.9% uptime across all SAP environments through proactive monitoring, automated failover configurations, and rapid incident response within agreed SLA targets.
40% Reduction in Critical Incidents
Proactive monitoring and root cause analysis eliminated recurring issues, cutting critical P1/P2 incidents by 40% compared to the pre-managed-services baseline.
Improved S/4HANA Performance
Performance tuning of SAP S/4HANA workloads on AWS — including HANA memory management, batch job scheduling, and EC2 right-sizing — delivered measurable improvements in transaction response times.
Seamless Integration
End-to-end monitoring of third-party application interfaces ensured consistent data flow between SAP ECC and AWS-hosted systems, eliminating integration blind spots.
20–25% Cost Savings
Infrastructure cost optimisation through EC2 right-sizing, Reserved Instance adoption, EBS volume tiering, and S3 lifecycle policies delivered sustained savings of 20–25%.
