About Carnival


vessels across 10 cruise lines

uptime for ship operations


    • Slow and unreliable network connectivity at sea
    • Difficulty capturing and reacting to passenger activity in order to provide highly personalized experiences
    • Real-time responsiveness wasn’t achievable without high scalability for vast amounts of personalized data


    • OceanMedallion system captures and matches behavior-based preferences by guests, increasing brand loyalty and upsells
    • Automatic syncing to geographically convenient AWS data centers provides real-time speed impervious to internet disruption
    • Guest profiles and preference data are securely stored for future voyages
Right now, we produce more information on a single MedallionClass cruise than would have been created in the whole history of the cruise line. All that intelligence has to be processed on the edge so it can be invested back into the guest experience in real time.
