Enterprise Cloud Migration at Scale for Fortune 500
Migrating 200+ applications to multi-cloud architecture with zero downtime and 40% infrastructure cost reduction.
The Challenge
A Fortune 500 manufacturing company was operating a complex IT landscape with over 200 applications running across multiple data centers globally. The aging infrastructure was increasingly expensive to maintain, and the organization lacked the agility to respond quickly to business needs.
The company needed to modernize their infrastructure while maintaining business continuity. Many applications were mission-critical with zero tolerance for downtime, and the organization required a multi-cloud strategy to avoid vendor lock-in and meet regional compliance requirements.
- 200+ applications across 8 global data centers
- $50M+ annual infrastructure spend
- Many legacy applications with limited documentation
- Complex interdependencies between systems
- Strict compliance requirements (SOX, GDPR, regional regulations)
Our Solution
We developed a comprehensive migration strategy using a factory-based approach that could handle large volumes of applications while maintaining quality and minimizing risk. The solution included multi-cloud architecture spanning AWS and Azure based on workload characteristics and regional requirements.
Key to the success was our migration factory methodology that standardized the assessment, planning, and execution processes while remaining flexible enough to handle the unique requirements of each application.
- Application portfolio assessment and rationalization
- Multi-cloud landing zone architecture (AWS and Azure)
- Automated migration tooling and runbooks
- Wave-based migration execution with rollback capabilities
- Comprehensive testing and validation frameworks
- 24/7 migration operations center
Implementation Approach
We organized the migration into waves based on application criticality, complexity, and interdependencies. Each wave followed our proven methodology with built-in checkpoints and rollback procedures.
- Phase 1: Discovery, assessment, and migration strategy
- Phase 2: Landing zone setup and governance framework
- Phase 3: Pilot migrations (20 low-risk applications)
- Phase 4: Wave migrations (180 applications in 12 waves)
- Phase 5: Data center decommissioning and optimization
