What challenges did you run into?

During a recent project to migrate a legacy application to a microservices architecture, I encountered several challenges. First, the monolithic codebase had tightly coupled components, making it difficult to isolate services without breaking functionality. To address this, I used a strangler pattern, gradually replacing parts of the monolith with new services while keeping the core system operational. Second, data consistency became an issue because each microservice needed its own database. I implemented eventual consistency with event-driven communication and used a saga pattern to manage distributed transactions. Third, the team lacked experience with container orchestration, leading to deployment delays. I organized a series of hands‑on workshops on Kubernetes, which accelerated onboarding and reduced deployment time by 40%. Throughout the process, I maintained clear documentation and held regular retrospectives to capture lessons learned. These steps not only resolved the immediate obstacles but also established a scalable, maintainable architecture for future growth.
