Amazon Web Services and VMware have be named leaders in the cloud space by the 451 Research Vendor Window assessment.
The findings (which are based on responses from over 1,500 IT professionals worldwide) show that Amazon Web Services (AWS) retained the top stop in infrastructure-as-a-service (IaaS) adoption among enterprise buyers.
AWS is used by the majority of enterprise IaaS customers in the study (57 per cent) and is also cited as the most important IaaS provider by 35 per cent of these current IaaS customers.
VMware dominated the on-premises private cloud market with its ESX and vCloud offerings, being adopted by 70 per cent of surveyed enterprises.
However, Microsoft Azure, OpenStack and Rackspace are keeping the two market leaders on their toes, as they are rapidly becoming more and more popular in this space.
Microsoft Azure has been adopted by 42 per cent of enterprises surveyed and is listed most often as the vendor that enterprises will likely evaluate for their next IaaS supplier.
Michelle Bailey, senior vice president of digital infrastructure and data strategy at 451 Research, said: "While the 2015 Vendor Window for IaaS shows Amazon Web Services as the clear leader based on multiple metrics, Microsoft Azure, Rackspace and VMware’s vCloud Air are becoming competitive challengers.
"As more mainstream customers move business-critical workloads to cloud environments, the decision criteria for evaluating potential vendors change relative to early cloud adopters, and in turn so do the vendors under consideration."
