According to a 451 Research Vendor Window assessment, the battle for IaaS leadership has intensified even though Amazon Web Services (AWS) remains the clear front-runner. Respondents to the 451 vendor evaluations revealed that 57% of enterprise customers use AWS whereas Microsoft Azure is used by 42% of customers. AWS was cited as the most important customer in 35% of all cases, ahead of Microsoft Azure, which garnered 20% of votes in the same category. Rackspace earned the highest ratings for the IaaS vendor capable of fulfilling Guaranteed SLAs and was tied with AWS for its ability to fulfill customer needs. While AWS received high ratings with respect to Experience and Technical Innovation, Microsoft Azure, in contrast, was rated lower than most of its competitors with respect to Experience and Support for Open-Source Software. Meanwhile, in the private cloud market, the 451 Research Vendor Window Assessment found that VMware claims a presence in 70% of enterprises with its ESX and vCloud virtualization platforms. Nevertheless, the survey also found that more than 70% of VMware customers have deployed other solutions for private clouds such as OpenStack or Microsoft Cloud OS, for example.
Michelle Bailey, Senior Vice President, Digital Infrastructure and Data Strategy at the 451 Research Group, remarked on the significance of the findings as follows:
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.
Here, Bailey notes how the IaaS assessment reveals the emergence of “competitive challengers” to the leadership role of Amazon Web Services as the criteria for IaaS vendor selection evolves in relation to the evolving maturity of cloud adoption within the enterprise. The bottom line here is that, even though Amazon Web Services remains the most widely used and, in many ways, respected vendor within the IaaS space, enterprises are increasingly reviewing alternative options to AWS, particularly as the space features an increasing number of robust options that can variously go toe to toe with AWS regarding attributes such as customer service and ability to support SLAs. More importantly, the battle for IaaS market share is likely to become even more competitive as the progressive maturity of Big Data technologies and analytics means that enterprises are likely to seek cloud platforms that can not only support, but also streamline and simplify the adoption of Hadoop and NoSQL. Regardless, exciting times are ahead for the cloud industry as IaaS vendors mature their product and service offerings in ways that give customers the confidence to select multiple vendors to minimize risks of vendor lock-in while concomitantly enriching their knowledge of the IaaS space by sampling the heterogeneity of offerings available on the market today.
