At the start of the movie Star Trek II: The Wrath of Khan, Lt. Saavik took a test known as the Kobayashi Maru. The test was actually a trap to see how someone would handle a “no-win scenario” where any choice made would lead to a bad outcome. In network engineering, a Kobayashi Maru-like scenario is emerging for those who resist a move away from manual processes.
Embracing Automation is Key
One of my new rules is that “manual processes are the mortal enemy of network operations”. Earlier this month I wrote a post discussing the new rules of running a WAN, discussing how manual processes are bad for the business because they make the network a big choke point for the company, stifling business innovation.
Another New Year’s Resolution for Network Managers:
I Will Embrace Virtual Network Functions
In my blog near the beginning of the year, I urged network managers to make a resolution to not stick with the status quo when it comes to evaluating and selecting an SD-WAN solution provider, as it will ultimately prove a bad decision for the company and potentially the engineer’s career. Another resolution network managers must make in 2017 is to embrace the concept of virtual network functions (VNFs), particularly for branch office and remote locations.
Merriam-Webster defines the word “conundrum” as an “intricate and difficult problem”. This word can most certainly be used in a business context to describe the challenges associated with providing Internet access to branch and remote office workers. Legacy networks provided Internet access to users through a hub-and-spoke architecture — Internet connectivity came into the hub and then was distributed out to the branches via the spokes. This was never an ideal method of delivering Internet services since the traffic effectively traversed the WAN twice (to the branch and back); most companies lived with it, though, as Internet access wasn’t considered mission critical in the mid-90s.
In the popular comic strip Peanuts, Linus was always seen carrying his blanket. Clearly, the blanket gave the young lad a sense of comfort and security even in the face of his sister Lucy calling it a “stupid blanket” and constantly urging him to ditch it. To Linus, knowing the blanket was there was far more important than any kind of common sense that might make him consider giving it up.
