Engineering firm CH2M Hill recently began moving away from VMware ESX to Microsoft's Hyper-V. CH2M Hill has been using VMware technology since 2005, but recently began the push toward Hyper-V in an effort to increase savings through more virtualization. The engineering firm believes it will save over \$280,000 in software fees and \$3 million dollars in hardware costs over the next few years.
Additionally, CH2M Hill is using Microsoft System Center Virtual Machine Manager to allow business units to self-provision virtual servers. This has reduced the load on IT and allowed those business units to work more efficiently.
