• Resumen

  • Caught in a perfect storm of technology trends—including public and private cloud, Bring-Your-Own-Device (BYOD), converged storage, and VoIP—computer network management is reaching unprecedented levels of complexity. However, unlike server administrators whose tools have evolved with the times, network administrators are stuck using 20+-year-old box-by-box management tools. A new technology trend, Software-Defined Networking (SDN), promises to simplify network management.

    Although it seems like every vendor has its own definition of SDN, in this article, I make the claim that SDN is to networking what the DevOps movement is to server management: a way of making systems management easier to manage by adding programmable APIs that enable better automation, centralization, and debugging. In this article, I try to provide background on SDN, to snapshot its current and highly fluid state, and end with some predictions for what to expect next.
