Another morning and another announcement that yet another so called “Software defined Networking” (SDN) company will be acquired. This time it’s Oracle‘s turn, announcing the acquisition of Xsigo. The financial terms of the deal were not disclosed. Oracle did note that the two companies will continue to operate independently and it is “business as usual.” San Jose, CA-based Xsigo will mark Oracle’s sixth acquisition this year, after high profile purchases including social enterprise firms Collective Intellect and Vitrue. The deal is expected to go through in the fall, subject to closing conditions.
