Enthusiasm for the benefits of cloud-based services has been tempered only by lingering concerns regarding cloud computing security.
The findings of a recent study conducted by research firm IDC, however, may indicate that these concerns are rapidly fading and that a growing portion of companies now regard cloud data protection as dependable.
The study, entitled Worldwide and Regional Public IT Cloud Services 2011-2015 Forecast, predicted that global spending on public IT cloud services will expand from approximately $21.5 billion in 2010 to $72.9 billion in 2015.
Furthermore, the report claimed that cloud services are a critical component in a wide-scale transformation of the IT industry that, according to IDC, will drive growth for the next quarter of a century.
According to the report, in 2015, approximately 46 percent of all new net IT spending growth will be from public cloud services in five key sectors – applications, application development, systems infrastructure software, basic storage and servers.
Furthermore, Software-as-a-Service is expected to account for approximately 75 percent of all public cloud IT services throughout the forecast period.
Frank Gens, senior vice president and chief analyst for IDC, said that cloud computing services are integrating with other technologies, such as social networking, mobile devices and wireless networks.
"Together, these technologies are merging into the industry's third major platform for long-term growth," Gens said. "As during the mainframe and PC eras, the new platform promises to radically expand the users and uses of information technology, leading to a wide and entirely new variety of intelligent industry solutions."
The study's findings reiterate those of another recent IDC report, which found that enterprises in Europe are rapidly increasing their spending on consulting and migration to cloud computing solutions.
