Essentially every area of cloud computing is poised for huge growth over the next many years, but a recent report from Pierre Audoin Consultants found that the market for infrastructure-as-a-service will grow across the world by 2016. The industry will reach €70 billion, or more than $111.5 billion in 2016, which is up big time from the level of €21 billion, or more than $33.4 billion in 2011. The United States is currently the biggest user of IaaS, spending more than $19.1 billion in 2012.

"Public cloud services currently account for more than 10 percent of spending on IaaS services in the U.S. and between five and eight percent of spending on IaaS in major European countries," according to Sam Shead on ZDNet. "However, PAC predicts strong growth of public cloud and expects that it will account for between 20 and 30 percent of IaaS revenues by 2015, with countries in the Asia-Pacific region, such as India, China and Indonesia, showing the highest public cloud adoption rates."

Karsten Leclerque, principal consultant outsourcing cloud at PAC, said traditional IT services have been based on complexity while cloud has meant ease of use. However, but there should be a new competitive landscape as models like IaaS make their way into mainstream business thought.
