Over the past 10 years, FINN transitioned their monolithic Java application built on a Sybase database to a microservices architecture running on PostgreSQL, Kafka and Kubernetes. They broke the monolith into independent services but still struggled with dependencies on the legacy Sybase database. They learned it takes a long time to fully migrate and should focus on delivering value incrementally. While the transition is still ongoing, they have made major progress deploying new services and migrating data and are now 93% in Kubernetes with the goal of moving completely to the cloud.
