Microsoft est un des leaders dans le Magic Quadrant Gartner pour les infrastructures de virtualisation de serveurs X86
Et oui c’est fait, mais surtout quel long chemin d’accompli depuis 2003 et le rachat de la société Connectix, Microsoft fait maintenant parti des leaders dans le Magic Quadrant pour les infrastructures de virtualisation de serveurs X86 
Si l’on regarde l’analyse qui est faite de Microsoft cf https://www.gartner.com/technology/media-products/reprints/microsoft/vol2/article8a/article8a.html
Microsoft has been growing market share significantly since its launch of Hyper-V in 2008, and the subsequent addition of live migrations in Hyper-V R2 in late 2009. The company's success has been primarily occurring among midmarket customers new to virtualization, where it is winning at least 30% of the time.
One of Microsoft's key strengths — its low price — is also a weakness when it comes to influencing the channel to promote its product, rather than its competition. However, when evaluated objectively, Hyper-V and System Center Virtual Machine Manager (SCVMM) usually meet the requirements for midmarket or branch office deployments. In the past year, Microsoft has also released Windows Server 2008 Service Pack 1, with enhancements such as dynamic memory for Hyper-V. At the hypervisor and basic administration level, Microsoft has closed most of its technology gaps with market leader VMware (which tends to have an advantage with higher-level management and automation tools). The most significant hypervisor difference continues to be Microsoft's reliance on a parent operating system on each virtualization host — which carries the benefit of a proven driver architecture, but the burden of potentially more planned downtime for patching and maintenance (however, Microsoft's patch record to date for its parent operating system has been good).
In the past year, Microsoft has begun to lay out a broader virtualization road map for cloud computing, including Hyper-V Cloud, which includes some technology, white papers, consulting services and partnerships. While the vision is coming together, Microsoft's Hyper-V customers tend to be smaller enterprises or branch offices in larger enterprises — where private cloud computing is less likely to be deployed. Microsoft's challenge to become a leader in private cloud computing will be to convert existing VMware users to Hyper-V and System Center. In addition, service providers are cautious about leveraging Hyper-V for their own cloud-based offerings, given that Microsoft is a major service provider competitor with Microsoft Azure.
Strengths
Administrative environment that is familiar to Windows administrators
Midsize enterprise installed base of Windows
Strength of solution and price for midsize enterprises
Company financial strength
Cautions
Difficulty converting or surrounding strong VMware installed base, especially in large enterprises
Competing with VMware for channel and service provider influence
Hypervisor dependence on a running copy of Windows as a parent operating system
