Although still in its infancy, gaining traction has not been a problem. According to the latest market study by In-Stat, Infrastructure as a Service (IaaS) is set to grow to roughly $4 billion by 2015.
"Growth is expected in all public cloud service segments," says Greg Potter, Analyst at In-Stat.
Many Software-as-a-Service (SaaS) applications have been around for a long time, but now with the advent of entire platforms for these applications they're gaining the necessary visibility among businesses to reach renewed momentum in the marketplace.
Infrastructure-as-a-Service (SaaS) is also gaining increased traction, especially in the small business market.
In-Stat's latest market study includes the following insights:
- SaaS (software as a service) is poised to grow 142 percent between 2010 and 2015.
- Overall public cloud computing (IaaS, SaaS, and PaaS) is set to grow 153 percent from 2010 to 2015.
- Small business (5 to 99 employees) is the fastest growing size segment growing from $2.5 billion by 2010 to $6.6 billion by 2015.
- Small business account for over half of the market in SaaS and IaaS.
According to the In-Stat assessment, the top five vertical markets for IaaS offerings, in terms of 2011 market revenue, will be hospitality and food, healthcare and social services, and retail trade. The bottom 5 verticals will be mining, forestry, fishing, and agricultural services and utilities.
