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

01

Assessment & Planning

Analyzed the monolith, identified service boundaries, and created a migration roadmap.

02

Containerization

Dockerized services, set up Kubernetes cluster, and implemented service mesh for communication.

03

Data Migration

Migrated databases with zero downtime using blue-green deployment strategy.

04

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.
