Improving economic conditions and exposure to technology is driving the uptake of cloud-based communications applications in the US and Europe.
According to Frost & Sullivan's Future of Cloud Computing Technologies in Enterprises study, the complexity of communications is driving large enterprises to deploy cloud technologies more rapidly than small and medium businesses.
A survey by the analyst found that 57% of businesses said they were "cloud reliant", while 43% described themselves as "cloud lagging" or had an unfavourable view of the cloud.
About 70% of US and 56% of European businesses who took part in the survey found cloud technologies to be highly effective, indicating that exposure to these technologies can lead to wider adoption.
More than half of the surveyed businesses in the US and Europe have already moved 50% or more of their enterprise communications solutions to the cloud. Within the next three years, almost a quarter are likely to migrate 76% or more of their communications solutions to the cloud, Frost & Sullivan found.
