Public cloud growing more than three times faster than the overall software market
IDC forecasts global public cloud services market to reach $195 billion in 2020
According to the latest research report by IDC (www.idc.com), the global public cloud services market is projected to reach $195 billion in 2020. This figure is more than double the 2016 forecast of $96.5 billion. The market is expected to record an average annual growth rate of 20.4% over the five years from 2015 to 2020.
In 2015, cloud software, including SaaS and PaaS, accounted for 83.7% of the total public cloud market, while IaaS accounted for the remaining 16.3%. In terms of growth, the IaaS (Infrastructure as a Service) and PaaS (Platform as a Service) markets are expected to expand their share of the market as they grow at a faster pace than the SaaS market.

Benjamin McGrath, a researcher at IDC’s SaaS and Business Models Research Group, stated, “Over the next five years, cloud software growth will significantly outpace traditional software market growth,” adding that it will grow more than three times faster than the overall software market and become the growth driver for all practical software markets. McGrath continued, “By 2020, 50% of all new business software purchases will be in the cloud, and as a result, cloud software will account for a quarter of all software sold.”
The industries leading public cloud service spending are assembly manufacturing and banking and professional services, with these three sectors projected to account for one-third of global market revenue in 2016. The media, telecommunications, and retail sectors were identified as the industries expected to experience the fastest growth over the next five years. Notably, all 20 industry sectors included in this report are expected to more than double their revenue during the forecast period.
Market size in 2020 expected to more than double that of 2016
Eileen Simth, Program Director of Customer Insights and Analysis at IDC, noted that cloud computing is breaking down existing technological barriers, stating, "Both business unit leaders and IT organizations are relying on the cloud to deliver IT resources faster and at lower costs." She added that by no longer being constrained by the limitations of existing legacy IT environments, companies are able to adapt more quickly to market changes and take on greater risks.
The United States is the largest public cloud service market in terms of market size and is projected to account for two-thirds of global revenue during the forecast period, followed by Western Europe and the Asia-Pacific region (excluding Japan). Meanwhile, South America and the Asia-Pacific region (excluding Japan) are expected to grow at the fastest pace over the next five years.
