When Global Manufacturing Inc. approached us, they were struggling with aging infrastructure, rising maintenance costs, and scalability issues. Here's how we successfully migrated their entire operation to the cloud.
The Challenge
Legacy Infrastructure Problems
Global Manufacturing Inc. faced several critical issues:
- Aging Hardware: Servers over 8 years old requiring frequent maintenance
- Scalability Constraints: Unable to handle seasonal demand spikes
- High Operating Costs: $2.3M annually in infrastructure maintenance
- Security Vulnerabilities: Outdated systems with limited security updates
- Limited Disaster Recovery: Basic backup systems with long recovery times
Business Impact
These infrastructure challenges were affecting business operations:
- 23% increase in downtime over the previous year
- Inability to expand to new markets due to capacity constraints
- Rising IT costs consuming 15% of revenue
- Compliance issues with industry regulations
Our Approach
Assessment Phase (Week 1-2)
We conducted a comprehensive infrastructure audit:
- Application Inventory: Cataloged 127 applications across 45 servers
- Dependency Mapping: Identified critical application interdependencies
- Performance Baselines: Established current performance metrics
- Cost Analysis: Detailed breakdown of existing infrastructure costs
Migration Strategy (Week 3-4)
Based on our assessment, we developed a phased migration plan:
Phase 1: Quick Wins (Low-risk applications)
- Static websites and documentation
- Development and testing environments
- Non-critical internal tools
Phase 2: Core Applications (Medium-risk)
- ERP system and databases
- Customer-facing applications
- File storage and collaboration tools
Phase 3: Mission-Critical Systems (High-risk)
- Manufacturing execution systems
- Real-time monitoring applications
- Financial and compliance systems
Implementation
Cloud Architecture Design
We designed a robust, scalable cloud architecture:
Multi-Region Setup
- Primary Region: US East (production workloads)
- Secondary Region: US West (disaster recovery)
- Edge Locations: Global CDN for improved performance
Security Framework
- Network Segmentation: VPCs with private subnets for sensitive data
- Identity Management: Single sign-on with multi-factor authentication
- Encryption: Data encryption at rest and in transit
- Monitoring: 24/7 security monitoring and threat detection
Migration Execution
Week 5-8: Phase 1 Migration
- Migrated 15 low-risk applications
- Established CI/CD pipelines
- Implemented monitoring and alerting
- Conducted user training sessions
Week 9-16: Phase 2 Migration
- Migrated ERP system with zero downtime using blue-green deployment
- Set up automated backup and disaster recovery
- Optimized database performance in the cloud
- Implemented auto-scaling for variable workloads
Week 17-24: Phase 3 Migration
- Carefully migrated mission-critical manufacturing systems
- Extensive testing and validation procedures
- Real-time monitoring integration
- Compliance validation and documentation
