The Business Need: A Decade-Old Monolith Slowing Innovation.
A leading financial services firm was struggling to evolve its core claims processing platform, which had been in use for over 10 years. Built as a legacy monolith, the application had grown unwieldy and brittle:
Key Challenges
- Feature updates took weeks or even months to deploy.
- Every release risked breaking unrelated modules.
- The tightly coupled codebase made onboarding new developers difficult.
- Production incidents were increasing as the system aged.
The platform had become a blocker to innovation, limiting the firm's ability to meet changing customer expectations, comply with new regulations, or launch new offerings. The firm needed a path to modernization—without disrupting daily operations.
The Solution: Modular Microservices + AI-Augmented Refactoring on Azure
Syncortex was brought in to modernize the legacy platform, with a focus on maintaining business continuity while increasing system agility.
Key elements of the solution:
AI-Augmented Code Refactoring
Used AI-driven code analysis and suggestion tools to accelerate refactoring of over 200,000 lines of legacy .NET code, identifying modular boundaries and unused logic.
Microservices Architecture
Re-architected the monolith into modular, domain-driven microservices, improving separation of concerns, team autonomy, and service scalability.
Azure-Native Deployment
Deployed the modernized components on Azure Kubernetes Service (AKS) and Azure Functions, with CI/CD pipelines for automated deployment and rollback.
Phased Migration Plan
Introduced service strangulation to isolate and migrate features module by module—ensuring the legacy system could co-exist with modern services during the transition.
Observability & Reliability
Implemented centralized logging, APM, and alerting using Azure Monitor and Application Insights to reduce MTTR and improve system observability.
The Outcome: Agility and Stability Delivered in Parallel
The project was executed in under 3 months, transforming a decade-old system into a modern, maintainable, and scalable platform.
Key Results
200K+ lines of code migrated
Safely to modular services with no critical downtime.
60% faster turnaround time
For deploying new features, regulatory changes, and customer enhancements.
Production incidents reduced by 45%
Due to service isolation and better error handling.
Onboarding time for developers cut in half
Thanks to cleaner codebases and better service documentation.
The Impact: A Platform Built for the Next Decade
The modernization initiative helped the financial firm move from legacy limitation to digital agility—positioning them to innovate faster and serve customers better.
Long-term Business Benefits
- Enabled DevOps practices and CI/CD culture, reducing reliance on manual deployments.
- Improved security and audit readiness, leveraging Azure's compliance-ready stack.
- Created a modular foundation for future expansion into digital claims, AI-based approvals, and customer-facing portals.
- Extended the platform's lifespan, while preparing it for AI, cloud-native analytics, and workflow automation.
