Problem
A major insurance company faced high total cost of ownership and limited flexibility of its existing databases. Licensing was too expensive, and scalability did not allow the development of new services at the required pace. At the same time, the company could not afford extended downtime or data loss risks during the transition. The challenge was to find an optimal solution that would reduce costs while ensuring the reliability of mission-critical systems.
Solution
We proposed a consulting strategy and phased migration to PostgreSQL — an open-source, scalable DBMS that proved to be the optimal choice for the insurance business. Our team designed the migration with full compatibility across business applications, minimized downtime, and ensured complete quality control. Key elements of the solution: Audit of the existing database and all dependencies. Development of a migration roadmap with risk mitigation. Optimization of the architecture for PostgreSQL. Application and service compatibility testing. Data migration with minimal downtime. Setup of backup and replication processes. Implementation of monitoring and alerting systems (Prometheus/Grafana). Training of the client’s internal IT team.
Result
The company gained a modern, high-performance, and cost-efficient data platform. PostgreSQL delivered scalability, fault tolerance, and flexibility while eliminating dependence on expensive licenses. Key outcomes: Reduced licensing and maintenance costs. Improved data processing performance. Minimal downtime during migration. Enhanced security and fault tolerance. Flexibility and scalability for future services. Trained internal team for ongoing support. Conclusion: Migration to PostgreSQL became a key step in optimizing the company’s IT infrastructure, laying the foundation for future business growth and innovation.
