Infrastructure as a service (IaaS) cloud revenue is expected to triple to $43.6 billion by 2020, up from $12.6 billion in 2015, according to research firm IDC.
The projection, which equates to a compound annual growth rate of 28.2 percent over five years, is based on the number of enterprises ditching on-premises hardware for the public cloud.
IDC said a survey of more than 6,000 IT organizations found two-thirds are using or planning to use IaaS. IDC noted that "public cloud IaaS is slowly transforming the enterprise IT value chain".
In 2015, IDC said the IaaS market grew 51 percent and there would be a 41-percent growth through 2016 and 2017.
