Over one-fifth of CIOs and business unit managers from both small and medium-sized enterprise (SME) and enterprise-scale organisations across Australia said they are currently using cloud computing, according to IDC’s APEJ Cloud End-User Survey 2011.

The survey also found that 32.4% of the respondents are planning to use it within the next 6 to 12 months and 41.2% after 12 months.

According to IDC, cloud services model is just one core ingredient which is emerging as the industry’s third platform for growth.

Mobile devices and apps expanding the edge of the digital world beyond PCs; cloud services replacing the client/server model as new architecture for offering delivery; and mobile broadband connecting the edge to the core are the core ingredients for this platform.

Two important technologies – "big data" analytics and social technologies – are creating value on top of this foundation, IDC said.

Cloud services revenue in Australia is forecast to increase from AUD$470.3m in 2010, to AUD$2.03bn in 2015, representing a compound annual growth rate (CAGR) of 34%.

The predicted revenues will be from applications, application development and deployment (AD&D), systems infrastructure software, basic storage and servers.

The end user survey for Australia indicated that 29% of the respondents are using or planning to use a virtual private cloud (vPC), which is a cloud service provided through a secured network by a cloud service provider.

"IDC predicts the emergence of a sizeable opportunity to provide professional services around cloud assessment, planning, workload migration, security best practices, governance, and test case procedures," said Raj.
