Xen and KVM, like other virtualization tools, can be used as part of a comprehensive datacenter architecture. One of the most important value propositions offered by both of these tools is low initial cost (read "free").
Virtualization reaches from hand-held devices to the data center to the clouds. Virtually Speaking examines the forces behind this expansion, the suppliers of the technology and the organizations using the technology.
Daniel Kusnetzky, a reformed software engineer and product manager, founded Kusnetzky Group LLC in 2006.
