Avanade notes that cloud services are becoming more mainstream but one in five executives surveyed finds it impossible to manage the disparate cloud services within their organisation.

The "Has Cloud Computing Matured?" survey was conducted by Kelton Research, an independent research firm, in March to April 2011. The research firm surveyed 573 C-level executives, IT decision makers and business unit leaders at top companies located in 18 countries across North America, South America, Europe and the Asia Pacific.

About 60 per cent of respondents are worried about the unmanaged adoption of public cloud services within an organisation.

Avanade emphasises that cloud computing is definitely maturing in the enterprise as chief information officers are migrating towards cloud services to achieve business benefits, such as improved flexibility, reduced costs and helping to speed time to market.
