Norway's Avinor group is moving operations at all its 46 airports to Amadeus' cloud-based Airport Common Use Service (ACUS) platform.
The state-owned company will initially implement the platform at eight airports and will later extend it to all its airports.
The use of the platform will allow the airports to access and deploy passenger processing systems both within and outside the terminal.
Avinor expects the technology to be useful during disruptions as the data is accessible through a PC, laptop or a mobile device.
Avinor Group CIO Brede Nielsen said: "Switching to the cloud will help pave the road to this objective and change the traditional passenger-processing environment at airports for the better.
"Furthermore, by using Amadeus' technology, The Avinor Group will be able to provide our airports with an innovative technology solution at a 25% cost reduction to the previous CUTE/CUPPS service whilst increasing customer satisfaction."
Airports and airlines will also be able to reduced their service costs and save on the wide area network (WAN) connections.
Amadeus Airport IT Head John Jarrell said: "The Avinor Group's adoption of ACUS shows that technology in the aviation industry is moving towards a model that encourages innovation and flexibility.
"Our cloud-based platform is central to Amadeus' broader commitment to improve airports' operational efficiency and the passenger experience."
Owing to the reduction of infrastructure and hardware, Amadeus expects to help Avinor airports cut down CO2 emissions by 5,000t annually.
