Modernizing Microsoft Workloads on AWS for Performance, Resilience and Scale
Migrating critical Windows Server and SQL Server workloads to AWS to reduce latency, improve availability and optimize enterprise operations.
The objective of this project was to modernize and optimize Ergos' Microsoft-based application environment by migrating workloads to AWS to address latency challenges, reduce operational overhead, and improve availability and performance.
The customer was running business-critical applications built on Microsoft Windows Server and Microsoft SQL Server, which experienced performance limitations and operational complexity.
The solution involved migrating workloads to AWS using:
- • Amazon EC2 for Windows Server
- • Microsoft SQL Server on EC2
- • Provisioned IOPS SSD (io1/io2)
- • Multi-AZ architecture
- • AWS Backup
- • Amazon S3
- • Amazon CloudWatch
- • AWS IAM
- • AWS Systems Manager
Result: Improved performance, automated operations, enhanced security and enterprise-grade reliability.

Detailed Solution Architecture
1. Microsoft Compute Layer
Amazon EC2 instances running Windows Server provide the core compute platform. SQL Server is hosted on dedicated, performance-optimized EC2 instances with workload-specific sizing to ensure consistent throughput for data-intensive enterprise applications.
2. SQL Server Performance Optimization
Storage architecture separates OS, database data, and transaction log volumes using Provisioned IOPS SSD (io1/io2) to eliminate I/O contention. This dedicated volume strategy ensures SQL Server delivers predictable, high-performance query execution and transaction processing.
3. Multi-AZ High Availability Architecture
Multi-AZ deployment ensures resilience across AWS Availability Zones. The architecture provides automatic failover capabilities, eliminating single points of failure and ensuring service continuity for business-critical Windows and SQL Server workloads.
4. Monitoring & Operations Management
Amazon CloudWatch provides comprehensive monitoring across CPU utilization, memory, disk I/O, and network performance. Threshold-based alarms (CPU >80%, disk capacity) trigger proactive notifications, enabling the operations team to respond before issues impact end users.
5. Backup Architecture
AWS Backup automates EBS snapshot creation and management. Amazon S3 provides durable, cost-effective backup storage with configurable recovery retention policies. This eliminates manual backup processes and ensures consistent data protection across all workloads.
6. Security & Compliance
IAM policies enforce least-privilege access controls. RDP access (port 3389) is restricted to authorized networks. SQL Server access is limited to internal application traffic. All EBS volumes are encrypted at rest. AWS Systems Manager automates OS patching to maintain security posture.
7. Operational Efficiency Improvements
- • Reduced manual maintenance tasks
- • Automated patching via AWS Systems Manager
- • Simplified lifecycle management
- • Reduced dependency on hardware operations
