VMware is relatively expensive so companies often look for a lower-cost alternative. Citrix Hypervisor offers enterprise-grade features but at a lower cost when compared to VMware vSphere. Interestingly, Hypervisor is the industry leader when it comes to supporting 3D graphics in a virtualization environment which can be really important for some scenarios. Hypervisor also supports both Linux and Windows.
Most users rate Citrix Hypervisor slightly behind VMWare but the difference is not that big. Furthermore, Hypervisor is particularly popular with small and medium sized businesses. It’s a good option if you already purchase Citrix software and where there is a real mix of both Windows and Linux OS applications in your company. However, if your solutions are dominated by either Linux or Windows you might want to choose another vendor.
