Gartner Names Microsoft and VMware as Server Virtualization Leaders

Gartner has released its 2015 "Magic Quadrant" for x86 server virtualization infrastructure, which found that Microsoft and VMware are leading the pack in that market.

VMware was rated highest by a significant margin, ranking at the top for both "Completeness of Vision" and "Ability to Execute." Microsoft was behind in both categories, but was still far ahead of the other five companies listed as important in server virtualization: Oracle, Odin, Red Hat, Citrix and Huawei. They had a place as "Niche Players."

VMware: Still King of the Hill
As part of its analysis, every Magic Quadrant report lists strengths and cautions for each vendor. It's still bullish on VMware: "VMware continues to have dominant market share, and customers remain very satisfied with product capabilities and vendor support," the report states, adding that the company is still growing at a healthy clip.

Despite those strengths, the report points out a number of challenges for VMware, and many come from Microsoft. "Client inquiries have been significantly increasing about comparisons between VMware and Hyper-V, specifically," Gartner says. In the SMB space, especially, Microsoft is becoming a threat: "… as Microsoft gains marketing momentum, VMware will need to continue to offer low-price packages to remain competitive in this market."

Another concern for VMware is its lack of traction in public cloud, which Gartner says could have large ramifications down the road: "While VMware has a dominant share for existing enterprise workloads, its share of the newer, cloud workloads is much smaller — a major inhibitor to growth."

On the whole, though, Gartner gives VMware high marks for its vision that extends virtualization from the datacenter to the cloud, strong technology and customer satisfaction.

Microsoft: A Solid Contender
In what should be considered a major victory for Redmond, Gartner says that Microsoft "… has effectively closed most of the functionality gap with VMware in terms of the x86 server virtualization infrastructure." That's good news for companies whose virtualization efforts are newer or less entrenched, as it means there are more comparable options.

The issue then becomes one of saturation, as most shops have already put their server virtualization infrastructures in place. "Its challenge is neither feature nor functions, but competing in a market with an entrenched competitor, VMware," Gartner says. Microsoft is winning a "good" percentage of enterprises still implementing virtualization, the report states, but there aren't that many out there.

One area in which Microsoft still falls short of VMware is in its virtualization management tools, which Gartner says "… have some ease-of-use weaknesses."

On the other hand, Microsoft has an advantage it's maintained since the early days when it made Hyper-V free: price. How much of an advantage this remains is a debatable question, but enterprises that have a large percentage of Windows workloads virtualized are the most likely to standardize on Hyper-V, since it's free.

Citrix: A New Direction
Citrix used to be in the "Leaders" quadrant, but has seen that position slip over the years, to where Gartner now considers it a "Niche Player." The report this year has both good news and bad news. First, Gartner believes Citrix has thrown in the towel when it comes to the leaders: "… it is clear Citrix is no longer investing to keep up with market leaders VMware and Microsoft — at least for traditional server virtualization in the data center," the report states.

However, Gartner sees this less as a failing than a new direction, into cloud computing. From the report: "For cloud infrastructures, the Xen hypervisor will remain the most widely used architecture for public infrastructure as a service (IaaS) cloud providers, if for no other reason than it is used by Amazon Web Services." Gartner sees Citrix's goal as to grow its CloudPlatform business.

Since 2012, Gartner has downgraded Citrix on a consistent basis. It started as a "Leader," dropped to a "Visionary" in 2013, then tumbled again into the "Niche Player" category last year.

One interesting note is that Gartner estimates that "About 75% of x86 server workloads are virtualized," but adds that virtualization technologies "are becoming more lightweight." It doesn't specifically say so, but it would be safe to assume that containers, like Docker, is at least part of what Gartner means.
