Global Manufacturing Corp, a Fortune 500 company with operations spanning 40 countries, faced significant challenges with their aging on-premises infrastructure. Their legacy systems were struggling to keep up with business growth, and maintenance costs were escalating. The company needed a comprehensive cloud migration strategy to modernize their IT infrastructure while maintaining business continuity.

The Challenge

The primary challenges included migrating over 500 servers, 200+ databases, and numerous legacy applications without disrupting operations. The company operated 24/7 manufacturing facilities, making downtime unacceptable. Data security and compliance requirements were stringent, with regulations spanning multiple jurisdictions. The existing infrastructure lacked scalability, making it difficult to respond to seasonal demand fluctuations.

Legacy applications were tightly coupled with specific hardware configurations, requiring careful assessment and refactoring. Network connectivity between global locations needed optimization. The migration had to be completed within 18 months while maintaining all existing functionality and improving performance.

Our Solution

We developed a phased migration strategy using a hybrid cloud approach. Critical production systems were migrated to AWS with multi-region redundancy, while development and testing environments moved to Azure. We implemented Infrastructure as Code (IaC) using Terraform, enabling consistent, repeatable deployments across environments.

Database migration involved a combination of lift-and-shift for compatible systems and refactoring for legacy databases. We implemented automated backup and disaster recovery solutions, reducing recovery time objectives from days to hours. Containerization with Docker and Kubernetes enabled better resource utilization and simplified deployment processes.

Results and Impact

The migration resulted in a 45% reduction in infrastructure costs through optimized resource utilization and elimination of hardware maintenance. System performance improved by 60%, with average response times decreasing from 2.5 seconds to under 1 second. Scalability now allows the company to handle 3x peak traffic without performance degradation.

Business continuity was maintained throughout the migration with zero unplanned downtime. Disaster recovery capabilities improved significantly, with automated failover reducing recovery time from 48 hours to under 4 hours. The new infrastructure supports the company's growth plans and enables rapid deployment of new services.
