Abstracting the network with SDNs

A New Nexus


Even as the tech world works to figure out just what to do with the potential of cloud computing and big data, along comes a new bit of technology fueled by open source software: software-defined networks.

Technology these days is all about abstraction: cloud computing is basically abstracting the concept of servers, so you don’t have to worry about them. Big data’s non-relational databases and Hadoop clusters perform a similar level of abstraction on database administration, and software-defined networks (SDNs) aim to do the same thing with networking.
