Case Study: a European lending marketplace achieves seamless monolith-to-microservices migration with Intellias

Platform Migration Strategy: Decomposing a Monolith to Microservices

The customer, a European lending marketplace, faced the challenge of modernizing its legacy monolithic application to support significant growth without interrupting its service. To achieve this, they partnered with Intellias to refactor the system’s architecture from a monolith to microservices.

Intellias implemented a two-step refactoring strategy, developing new features as microservices while gradually extracting services from the existing monolith. This approach, combined with blue-green deployment, ensured the platform remained 100% operational throughout the 1.5-year migration. The results for the customer included a stable, scalable product, a reduced allocation of rework tasks per sprint from 25% to 10%, and the establishment of a daily release cycle, achieving an ROI within one year.
