The travel industry is just one of dozens of sectors which have seen what many say is a major shift from off-the-shelf, version-based technology to Software-as-a-Service (SaaS).
A string of travel technology providers have adopted the model amid incessant chatter in the wider tech community as to the benefits of the having a SaaS programme to run critical systems such as reservations, booking, CRM, email and accounts.
But as the following clip from ZDNet explains, SaaS still accounts for just 4% of the overall global software marketplace and is only expected to double in size over the next three years.
The issue for the travel sector was brought into sharp focus just days ago when Air New Zealand found itself on the wrong end of a power outage from its technology provider IBM.
But the question remains: will the travel sector move toward a SaaS-based platform to run its systems, or will larger projects remain the preserve of traditional software?
