Mark J. Wicker


Experienced IT Leader and Senior Network Engineer with 26+ years in the business –

I believe that the future of the networking business is in automation. Some people now call this “SDN” or “Software Defined Networking”. I have been doing this for the last 10+ years with my scripts to automate multi VRF “cloud” tenant builds in Data Center environments. Back in the beginning of it, there was no such buzz-acronym as “SDN”. My version of “SDN” was writing IP aware “here document” scripts with logic tied inputs to generate and automate the correct configurations of entire network environments so that they could easily be deployed (error free) in minutes instead of hours. When tied with the API’s of various IPAM and DNS solutions, these scripts became fully automated home grown “SDN” solutions.

Because of my unique Unix/Linux system admin background where I learned how to script and automate common, repeatable tasks combined with many more years as a Cisco Senior Network Engineer and as a Leader of a global network engineering team. – I believe that I am on the forefront of what it means to be called a Senior Network Engineer in this day and age. I adhere to this same rule under which I have mentored all of my teams under – “Network Engineering, in this day and age and in the future, means that you need to be a developer/coder first who has an in depth understanding of networking protocols, standards and architecture”.
