One of the companies and technology to watch is Hotlink with its Cross Platform Management Technology (winner of Best of Show, VMworld 2012). If you have not heard of this before I think you will in the near future. This technology allows you to use VMware’s vCenter Server to manage and control all major hypervisors and public clouds to include VMware vSphere, Microsoft Hyper-V, Citrix XenServer, Red Hat Enterprise Linux (KVM), CloudStack, and Amazon EC2 all from within VMware vCenter.
If you are going to have more than one virtualization platform, you should not have more than one virtualization management stack. Hotlink SuperVISOR lets you use the market leading virtualization console (vCenter) to manage other virtualization platforms like Hyper-V, KVM, and XenServer. Furthermore it extends the vCenter API data used by third party management vendors with data from these other platforms, turning Hotlink into the management data broker for the virtualization management industry.
Virtual Computer have redefined virtual desktops delivery with their latest release, NxTop 4. In NxTop4 Virtual Computer have aimed to further improve their client-side hypervisor desktop management solution and to better harness the power of end-point PCs for local execution rather than requiring major investments in virtual machine server farms.
