Amazon Web Services (AWS) remains the leader in Infrastructure-as-a-Service (IaaS) adoption among enterprise IT buyers, while VMware leads in the on-premise Cloud platform, according to IT research and advisory company, 451 Research.
These findings were reflected in its latest Research’s Vendor Window and On-Premises Private Cloud Platforms Vendor Window assessments, which polled more than 1500 IT professionals globally on both overall enterprise adoption rates and customer ratings of vendor performance.
It showed that 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.
Additionally, AWS received some of the highest ratings overall for its ability to fulfill customer needs, particularly in terms of experience and technical innovation.
But, while the 2015 Vendor Window for IaaS shows AWS as the clear leader based on multiple metrics, Microsoft Azure, Rackspace and VMware’s vCloud Air are becoming competitive challengers, according to 451 Research digital infrastructure and data strategy senior vice-president, Michelle Bailey.
"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," she said.
As for the on-premises private Cloud platforms vendor window assessment, it indicated that VMware dominates with its ESX and vCloud offerings, with adoption by 70 per cent of surveyed enterprises. In addition, VMware and its partner solution, Cisco UCS, received the highest ratings in terms of promise and fulfillment, particularly on the attributes of company brand and platform reliability.
451 Research Cloud services and data research vice-president, Scott Ottaway, claimed even though VMware's market dominance continues, the survey results also indicated that more than 70 per cent of VMware customers have also deployed an alternative Cloud platform such as OpenStack, CloudStack or Microsoft Cloud OS.
"As open-source-based solutions continue to receive investment from major hardware and software vendors such as HP, IBM, Red Hat and Citrix, VMware’s dominance is under pressure, especially for mobile and Cloud-native applications," Ottaway mentioned.
He also added that on-premises private Cloud will continue to be a major investment for IT organisations, and will be the default Cloud environment for many enterprises. Also, Cloud suppliers offering SaaS, IaaS and hosted private Cloud solutions will increasingly compete and cooperate with on-premises private Cloud environments.
