Case Study: Expedia Affiliate Network achieves 25% faster key transactions and rapid incident resolution with AppDynamics

Expedia Books a 25% Boost in Performance with AppDynamics

Expedia Affiliate Network (EAN), part of Expedia and serving over 7,500 partners in 33 countries, needed end-to-end application visibility to find and fix performance problems faster. Existing monitoring only signaled that issues existed, leaving the team reactive and often taking hours to diagnose Severity 2/3 incidents—impacting partners and customers worldwide.

After a successful Proof of Concept, EAN deployed AppDynamics across hundreds of production nodes to pinpoint where time was spent in APIs and web apps, prioritize fixes, and alert suppliers directly. The result: MTTR for Severity 2/3 incidents fell from hours to minutes, key business transactions improved by more than 25%, systems stayed stable amid growth, and EAN realized full ROI in just over a year.
