Covéa

Managing Complex Event Streams

For Covéa, one of the leaders in the French insurance market (owner of MMA, MAAF, and GMF brands), reliability is paramount. Their event bus, built on Apache Karaf, handles critical data flows that power their insurance services, including claims processing and policy management.

The Approach

Gladtek provided a managed service model that combined deep technical expertise in OSGI/Karaf with agile team management. Our role was both strategic and operational.

Karaf Optimization & OSGI Mastery

• Runtime Performance: We performed deep tuning of the Karaf container, optimizing memory management and thread pools for high-concurrency event processing.
• Dynamic Updates: Leveraged OSGI’s modular nature to perform hot-fixes and module updates without restarting the entire system, ensuring continuous availability.

Agile Team Leadership

• Managed Support: We managed a dedicated team of 9 developers, implementing a streamlined ticket-to-code workflow that reduced the average time-to-fix for critical issues.
• Technical Mentorship: Beyond solving tickets, we mentored the team on OSGI best practices, reducing long-term technical debt.

Outcomes

Our involvement stabilized the mission-critical event bus and improved the overall agility of the development team:

• Zero Critical Downtime: Maintained 99.9% availability of the event bus during our tenure.
• Faster Resolution: Reduced support ticket backlog by 40% through better triage and technical oversight.
• Scalable Architecture: Enhanced the event bus to support new business lines without requiring a full rewrite.

Detailed Results

• Successfully managed team of 9 for ticket support
• Maintained critical event bus application on Apache Karaf
• Ensured system reliability for insurance operations
• Streamlined support ticket workflow and resolution
