In this industry, everyone seems to talk about innovation, but very few platforms exist which foster innovation. More times than not, "innovation" is simply a buzzword used by some marketing campaign to hawk something about as novel as twenty-year-old accounting software.
Innovation does occur, of course. But often real innovation leverages what already exists to create something which doesn't yet exist. It may borrow from the known, but it produces something previously unknown. For example, the industry has been going wild over cloud computing in the past few years, but many of the core cloud computing concept are actually old mainframe concepts reimagined in the world of commodity servers.
Making a Place for Innovation to Thrive
A bare-metal hypervisor -- like the one produced by the Xen Project -- can be an excellent platform for innovation. We think of hypervisors as old technology, plumbing for newer technologies like cloud -- and, indeed, they are. But the nature of the bare-metal hypervisor makes it an excellent platform for innovation to take place.
