Enterprise Cloud Migration
Migrating a legacy enterprise application to cloud-native architecture — zero downtime, 60% cost reduction.
Context
An established enterprise was running on aging infrastructure. Maintenance costs were rising, deployments were risky, and scaling was manual and slow.
The Problem
The monolithic application was expensive to run, difficult to update, and couldn't scale with demand. Every deployment was a high-stakes event.
Process
Assessment & Planning
Analyzed the monolith, identified service boundaries, and created a migration roadmap.
Containerization
Dockerized services, set up Kubernetes cluster, and implemented service mesh for communication.
Data Migration
Migrated databases with zero downtime using blue-green deployment strategy.
Optimization
Implemented auto-scaling, monitoring, and cost optimization across all services.
Design Decisions
Strangler fig pattern
Gradually replace the monolith instead of a risky big-bang migration. Reduce risk, maintain continuity.
Kubernetes over serverless
The team needed control over infrastructure and the ability to run legacy services alongside new ones.
Outcome
✦ Zero downtime during migration
✦ 60% reduction in infrastructure costs
✦ Deployments reduced from weeks to minutes
Reflection
“Cloud migration isn't about technology — it's about transforming how your organization builds and runs software.”
