Abstract
At Amadeus, we are constantly evolving our technology stack to support our business. Founded
as a Mainframe company, we have embraced for several years a SOA architecture, and are now
very much involved in cloud technologies.
This journey uncovered new challenges with the validation of our applications. From a monolith,
our QA groups now have to validate a myriad of interconnected software components. We
believe CA Service Virtualization offers a great solution to these problems.
This session will be about our challenges, how we are addressing them and what we have
achieved so far with CA Service Virtualization.
