The public cloud is already the most common IT environment among the respondents of this survey, with 43 percent running workloads hosted by a public provider.
Thirty-one percent are operating virtualized environments, 20 percent are running workloads on physical machines and 7 percent have set up private clouds.
As to specific platforms for production workloads, 42 percent of all respondents are using Amazon Web Services, and 29 percent are using VMware's vSphere virtualization platform. Seven percent are running physical servers and 4 percent are running environments on top of the KVM hypervisor.
Microsoft Azure, Citrix XenServer, Microsoft Hyper-V and Google Cloud Platform were cited as their most critical resource for production workloads by less than 5 percent of respondents.
Breaking out the private cloud users, 54 percent are running OpenStack and 14 percent are running CloudStack. The remaining one-third are using a variety of other cloud-building technologies.
Migration Plans 2016-2018
While the public cloud is already the most prevalent environment among the companies polled by CloudEndure -- used by 43 percent of respondents -- that share will only grow in the next couple of years.
Based on the respondents' migration plans, 56 percent will be using public cloud resources within a year, and 64 percent in two years -- representing annual growth of 22 percent.
Private cloud is being used to host 7 percent of current workloads, but will climb to 9 percent in a year, and stay at that mark after 2 years, according to CloudEndure.
What's striking from the results of the survey is the expected drop in share for non-cloud environments.
Virtual machines, now used by 31 percent of the organizations polled, will drop to 23 percent in 2016 and 17 percent by 2018, according to the migration plans shared by respondents.
And physical machines will decline from 20 percent this year, to 13 percent in 2017 and 9 percent by 2018.
