What happened to Software Defined Networking? A while back I wrote a post where I thought 2012 would be the year for Software Defined Network (SDN), and I am really surprised that this technology has not gained greater ground. Now that we are halfway through 2013, I find myself still waiting for adoption of this technology to really take off. With investments from companies like Cisco, IBM, Alcatel, Juniper Networks, Broadcom, Citrix, Dell, Google, HP, Intel, NEC, and Verizon, all of which have current SDN initiatives, SDN will assume a role in IT infrastructure at some point. It just seems like it is going to take a little while longer to catch on.
