Amadeus is a leading provider of travel software and solutions for the travel industry, with airlines alone using the technology to board over 1.8 billion passengers a year. As the biggest processor of worldwide travel bookings, Amadeus manages a huge daily workload and has absolutely no room for service outages. To keep up with its rapid growth and highly demanding end-users, Amadeus “boxes” its applications so they can be deployed on any private or public cloud. Amadeus uses Couchbase clusters and cross datacenter replication (XDCR) in all its datacenters to ensure high availability, resiliency, and a single source of truth for bookings.
