Article after article and post after post have compared and contrasted Xen, VMWare, Veridian, and a host of other virtualization technologies, with opinions on performance, management tools, implementations, etc., etc. in abundant supply. Inevitably when it comes to Xen, the story comes full circle with some sort of declaration about “data center readiness.” The definition of “ready for the data center” is quite subjective, of course, based largely on the author’s personal experience, skills, and their opinion of the technical capabilities of those managing this vague “data center” to which they are referring.  More ...

There is no question that virtualization has captured the attention of enterprises of all shapes and sizes. And it's easy to understand why - the benefits are simply undeniable. Who wouldn't be interested in lower TCO, better resource utilization, improved reliability, increased flexibility, and rapid deployment - among other gains?

One of the biggest newsmakers in virtualization has been the open source Xen project, and for good reason. The technology is very well designed, is extraordinarily fast and scalable, and is supported by EVERY major OS, server, and silicon vendor - even Microsoft. But as Xensource CTO Simon Crosby says, "the Xen hypervisor is an engine, and not a car.  A powerful engine that needs a great gearbox, shocks, tires and the body to go with it." More ...
