Case Study: Parnassia Groep achieves 80% Java subscription cost reduction and enhanced security with Azul Systems

By migrating Java apps to Azul JVMs, Parnassia Groep reduced Java subscription costs by 80%

Parnassia Groep, a Dutch mental-healthcare provider serving about 180,000 clients with 14,000 professionals, faced a complex Java estate threatened by mergers, changing healthcare regulations, sensitive patient data and Oracle’s changed Java licensing and security posture. To address compliance and security risks and reduce costs, Parnassia chose to migrate from Oracle Java to Azul and partnered with OpenValue to plan and execute the migration.

OpenValue implemented a fast, best-practice JDK migration to Azul (with close coordination as an Azul partner), eliminating the identified compliance and security risks while preserving compatibility and support for older Java versions. The migration delivered measurable impact — an 80% reduction in subscription costs — and produced no post-migration application issues; it also improved system visibility, clarified responsibilities, optimized change processes and boosted administrators’ skills, enabling Parnassia to focus more resources on patient care.
