Worldwide public cloud services revenues are set to reach over $195bn (£148bn) in 2020, more than doubling the current market size, according to research from IDC.
The semi-annual worldwide public cloud services spending guide predicted that western Europe will continue to be one fifth of the global market, with revenues growing from $15bn in 2015 to $38.6bn in 2020.
The UK will remain the largest market in western Europe, producing around 30 per cent of the region's total revenues. The next-largest markets are Germany and France which, together with the UK, account for 64 per cent of western Europe's total revenues in public cloud services.
Bo Lykkegaard, associate vice president, software and cloud services trackers at IDC, said: "Public cloud services have changed how European organisations evaluate and select software. Aspects such as very fast rollouts, continuous upgrades, and ease of post-implementation reconfiguration are now top criteria for new application purchases.
"Some European countries have started the adoption of public cloud services later than others, due to concerns related to information security, data location, solution availability, and other issues. However, IDC foresees that the public cloud movement will sweep across all of Europe and that some markets of cautious adoption will outgrow the others over the next five years."
Software-as-a-service (SaaS) was accountable for 66.9 per cent of all public cloud revenues in 2015, and IDC predicts it will remain the largest sector through to 2020. But platform-as-a-service and infrastructure-as-a-service revenues are expected to increase at a faster level than SaaS, increasing their market share by 2020.
