The Challenge
Aging Monolith Threatening Business Growth
A healthcare technology company's core platform—built 15 years ago—couldn't scale to meet growing demand. Feature development had slowed to a crawl, and the risk of critical failures increased monthly.
Key Pain Points
- 6-month feature delivery cycles due to monolith complexity
- Single point of failure threatening 99.9% SLA commitments
- Only 2 engineers understood the legacy codebase deeply
- Unable to adopt modern security and compliance requirements
Our Approach
16-Week Embedded Modernization Program
Our team embedded with their platform engineering group, systematically decomposing the monolith while ensuring zero disruption to production operations.
1
Assessment & Strategy
Weeks 1-3- Complete system archaeology and dependency mapping
- Domain boundary identification using DDD principles
- Strangler fig pattern strategy development
- Risk mitigation and rollback planning
2
Incremental Extraction
Weeks 4-12- Service extraction with embedded pair programming
- Continuous deployment with feature flags
- Parallel running and validation
- Progressive traffic migration
3
Completion & Capability Transfer
Weeks 13-16- Final service extraction and monolith retirement
- Platform team training and certification
- Operational playbooks and incident response
- Independent operation validation
The Solution
Modern Microservices Platform with DevOps Excellence
A fully decomposed, cloud-native platform with CI/CD automation and a team equipped to continue the modernization journey.
Technologies Used
Kubernetes
Go
PostgreSQL
Redis
Terraform
ArgoCD
Key Deliverables
- 12 extracted microservices from monolith
- Kubernetes-based deployment platform
- CI/CD pipeline with automated testing
- Comprehensive monitoring and observability
"The embedded approach was transformative. Our team didn't just get a new platform—they gained the skills and confidence to own and evolve it independently."
