Free VMware is a great product. For the price of two modern servers, you can have the power of twenty servers. Free VMware is an excellent product for organizations trying to be more productive with less resources. The most recent virtualization solutions are known as bare metal hypervisors. VMware ESXi (vSphere) is such a product. It can be downloaded and installed for free. Additionally, VMware is available as a hosted solution as well. I have a proven track record of installing and managing VMware Server on the CentOS Linux operating system for a very reasonable fee. Please contact me if I can be of service to your organization.
