This document summarizes Amadeus' transition to cloud computing over time. It discusses how Amadeus initially used public cloud platforms like Google Cloud for specific customers or applications before building out its own private cloud and Platform as a Service (PaaS) called Amadeus Cloud Services. Amadeus Cloud Services provides a unified operational model and tools to deploy applications across private and public clouds with increased stability, security, and efficiency compared to traditional hosting. The document outlines Amadeus' guided migration approach to move core applications onto its PaaS platform while minimizing code changes through containerization.

What are Cloud Services?
Infrastructure as a Service
Online services that abstract the user from the
management of hardware resources like CPU,
memory, storage, network…

Platform as a Service
Computing platform, typically including an operating
system, a programming-language execution
environment, a database and a web server
Software as a Service
Business model for applications where customers
pay for the service usage, with remote operations
and hosting, by opposition to customers paying for a
software license and then installing themselves their
software at their own premises.
General definition of cloud computing: using IT resources without necessarily owning
them. Concretely, many companies outsource their IT resources to remote data
centers.
