Case Study: Karavel achieves €294,306 in first-year savings and 4x ROI with AppDynamics

Frances #1 Travel Site Karavel Achieves 4x ROI

Karavel.com, France’s leading travel site with about 4 million monthly unique visitors and roughly 3,000 transactions per minute, moved from a monolithic WebLogic setup to a distributed SOA environment with 200+ Tomcat servers. That complexity, plus non‑optimized SQL, framework bugs and resource leaks, produced recurring performance problems and long mean‑time‑to‑resolution (with lengthy post‑mortems), and made existing tools impractical for production troubleshooting.

Karavel deployed AppDynamics in production and immediately auto‑discovered call‑stack bottlenecks, regressions and memory issues, enabling fast root‑cause analysis without consultants. In the first year they realized €294,306 in savings (4x projected ROI over two years), saw a 20% improvement in key transactions, cut Severity‑1 incidents from 30 to 11, reduced downtime by over 70%, and slashed MTTR from hours to minutes—while the easy‑to‑use tool was adopted by around 50 staff across business, dev and ops.
