We’re in the midst of a revolutionary shift in the enterprise data center that has not been seen in decades. At its core, this shift is being driven by the rise of “soft” infrastructure. Virtual machines and virtual networks and storage can be provisioned and reconfigured rapidly and in a highly automated way, rather than being limited by the constraints of hardware infrastructure that was built for a much less dynamic environment. The “software-defined data center,” as it is commonly known, has business repercussions that go well beyond transforming data center technology. It has shaken long-term alliances between technology giants. Vendors are scrambling to reposition themselves to best exploit this new era of soft IT.
