Legacy System Migration to Cloud

The Challenge:

  • Decade-old monolith causing frequent outages & slow deployments.
  • On-premise infrastructure cost growing 30% year-over-year.
  • Manual deployments taking days with high risk of failure.
  • No disaster recovery plan for critical retail operations.

Solution:

  • Assessed existing architecture & defined a phased migration roadmap.
  • Decomposed monolith into containerized microservices using Docker.
  • Implemented CI/CD pipelines with automated rollback capabilities.
  • Set up multi-region AWS deployment with failover & backup policies.

Features:

  • Discovery: Architecture audit & dependency mapping.
  • Design: Cloud-native service mesh & infrastructure blueprint.
  • Development: AWS ECS + Terraform for reproducible infra.
  • Testing: Chaos engineering & disaster recovery drills.

Results:

  • 99.9% uptime achieved within 3 months of migration.
  • 60% reduction in infrastructure costs within the first year.
  • Deployment time reduced from days to under 15 minutes.
  • Zero data loss across the full migration window.
