Case Study: American Express Global Business Travel achieves seamless, zero-downtime integration with WSO2 Enterprise Integrator

Using Open Source Technology to Solve Complex Integration Needs at American Express Global Business Travel

American Express Global Business Travel, a travel and meetings management company operating in 140 countries, needed a reliable orchestration layer to handle massive messaging and service-call volumes while modernizing a legacy integration system. Its existing Java-based setup was difficult to redeploy and customize, so the company chose WSO2 Enterprise Integrator to support its Global Trip Record™ platform and single source of trip data.

WSO2 implemented an open source, flexible integration architecture where all orchestration and message transformation flow through WSO2 Enterprise Integrator across more than 30 microservices. The solution has run for two years without downtime, supports hundreds of transactions and messages per second, and helped American Express Global Business Travel improve elasticity, reliability, and deployment efficiency, with strong support from WSO2 along the way.
