Software defined networking (SDN) has caused many network engineers to ask the question, “Will I have a job in the future?” I believe that everyone who is willing to stay current and update their skills will forever be employed. The key is staying current. What does that mean, exactly? I have a post coming about that, but for now I spied this picture. I think it captures some of what I believe will happen over the next several years.
When it comes to running your network, be the one controlling the tools. Don’t let your usefulness fade so that you’re of no more value than the tools themselves. If you’re simply a tool that can input commands into a CLI, then eventually, you will be replaced by something faster, less error-prone, and tightly integrated into a much larger IT engine.
