Software-Defined Networking Could Change the Way Applications Communicate

I've heard a lot of talk lately about software-defined networks (SDN). Just about every networking vendor is at least nodding at the concept, particularly as a way of handling more complex cloud-based environments. There have been a couple of high-profile announcements lately, and the technology is very interesting. While it seems like this is not quite ready for most businesses yet, it does offer the potential to change how complex networks work, and eventually to present some big changes for networks and customers of all sizes.
