SimpleX Internet provides virtualization at a reasonable price through its hosting services. Most customers used Windows Server with Linux server, but service was provided in a manner that could not integrate them. After Windows Server 2012 launched, SimpleX Internet tested Linux on Windows Server 2012. Linux on Windows Server 2012 showed the same performance as CenOS on Xen Hypervisor and the disk I/O performance was twice as good. SimpleX Internet plans to upgrade their service infrastructure to Windows Server 2012.
