Most UK CIOs see the cloud as the major game changer for their business, according to research from outsourcer Capgemini.
The cloud leads the "disruptive technologies" already being implemented by UK firms, with 60 percent pointing to its effect on their business.
The cloud is followed by mobile (50 percent), social (30 percent) and big data (28 percent), covering the four big ticket technology areas most firms are considering in the technology space.
In addition, over three-quarters (78 percent) of UK CIOs felt that their business had a "good" or "sufficient" understanding of the state of their applications portfolio.
And over half of UK CIOs say their IT spending will increase over the next five years - 45 percent cited an "increase" and 7 percent a "significant increase".
The UK figures are among responses from over 1,100 responses in total from the global research conducted by Capgemini.
Ivar Sinka, head of business architecture at Capgemini, said: "IT departments are moving out of the old stereotypes of simply facilitating cost reduction and risk management, to a more proactive role of business enablement through innovation in both application development and implementation.
"This is directly driven by the new possibilities and fundamental changes that disruptive technologies - cloud, mobile, social and big data - can bring, as well as a greater recognition and understanding from the business value they can deliver."
That said, the global research found that almost half of CIOs (48 percent) thought their business had more applications than it needed. Just 37 percent believed the majority of their applications were mission-critical.
Nearly three-quarters (73 percent) believed that at least one-fifth of their current applications share similar functionality and should be consolidated, and 57 percent thought at least a fifth of their applications should be retired or replaced.
