The study was commissioned, Norton told iTnews upon its release, for the benefit of CIOs in the travel and related industries standing on the precipice of replacing legacy, proprietary systems.
Airlines and railways in particular have sweated outdated mid-range and mainframe systems for several decades. Inevitably, CIOs at these organisations will need to choose between upgrades, outsourcing or adoption of cloud services.
In most cases, Norton argues that re-engineering internal IT using open source software is the more sensible outcome.
