Retail Chain Cloud Migration

Client Background

Organization: National Retail Chain

Size: 150 stores, 8,500+ employees

Revenue: $1.2 billion annually

Geographic Coverage: 25 states

IT Infrastructure: Legacy on-premises systems

Initial Cloud Migration Challenges

The retail chain faced significant challenges with their legacy infrastructure that were impacting business operations:

• Legacy System Limitations: Outdated systems unable to support modern retail operations
• High Infrastructure Costs: Expensive on-premises infrastructure and maintenance
• Limited Scalability: Inability to scale systems during peak shopping seasons
• Poor Performance: Slow system performance affecting customer experience
• Data Silos: Isolated systems preventing unified customer insights
• Security Vulnerabilities: Outdated security controls and compliance issues

Cloud Migration Strategy

Hybrid Cloud Architecture

Implementation of a hybrid cloud architecture that combines on-premises systems with cloud services for optimal performance and cost efficiency.

Cloud Architecture Components:

• Public Cloud Services: Microsoft Azure for scalable applications and services
• Private Cloud: On-premises private cloud for sensitive data and legacy systems
• Edge Computing: Edge services for real-time store operations
• Data Integration: Unified data platform across all systems
• Security Controls: Comprehensive security across all environments

Application Modernization

Modernization of legacy applications to leverage cloud-native capabilities and improve performance.

Modernization Approach:

• Lift and Shift: Migration of existing applications with minimal changes
• Refactoring: Modification of applications to leverage cloud services
• Cloud-Native Development: Development of new cloud-native applications
• API Integration: Integration of cloud and on-premises systems via APIs
• Microservices Architecture: Breaking down monolithic applications into microservices

Data Migration and Integration
