Case Study: CHIeru achieves 35% cost savings with Oracle OCI Database with PostgreSQL

CHIeru migrates to PostgreSQL on OCI and sees 35% cost savings

CHIeru, a company focused on connecting education and IT to support teachers across Japan, was managing multiple PostgreSQL servers across internal and external systems, creating a heavy operational burden for its development team. To improve efficiency, CHIeru worked with Oracle and used OCI Database with PostgreSQL as part of its migration journey.

Oracle helped CHIeru migrate and consolidate several PostgreSQL servers, first using Compute VM on OCI as a temporary step before moving to fully managed OCI PostgreSQL. The result was 35% cost savings, reduced operational overhead, and better performance, while simplifying day-to-day database management.
