At a recent discussion with delegates at Networking Field Day, Tom Hollingsworth wondered why SD-WAN startups have been able to be so aggressive with innovating in the space, while established networking companies have struggled to keep up. This is endemic of the technical debt a lot of larger organizations carry. He considers something like Cisco’s IWAN, in many ways a precursor to modern SD-WAN. This ended up being complicated and hard to deploy because of many of the technology decisions that Cisco made years ago, resulting in both a software and hardware supply chain constraints on IWAN. Compare this to a startup, like the recent Networking Field Day presenter CloudGenix, who could design a solution around a desired functionality, rather than with a set of constraints inherited as technical debt. This SD-WAN example is just one way of looking at the role of technical debt in product development for large organizations.
