By 2021, three-quarters of Singapore companies say they will outsource the majority of their IT infrastructure, of which half will move their infrastructure to the cloud. The top three cost savings, they say, will come from reducing IT infrastructure costs, implementing a cloud and virtualisation strategy as well as standardising their IT infrastructure. Conducted by Vanson Bourne, a research firm, the survey polled 480 IT decision makers in Singapore, Germany, France, United States and United Kingdom. The study was commissioned by Savvis, a cloud infrastructure and hosted IT provider.
