Lindsay Hill wants you to know networking jobs are shrinking:
I’ve seen some research from Gartner that indicates that organizations have been steadily decreasing their Network Operations teams over the last five years. They have also been reducing their Data Networks spend. (Sadly I don’t have publication rights for this research, so you’ll just have to take my word for it).
Thoughts On Why?
- Partly because networking is no longer a specialist skill. DevOps people can do it and are doing networking differently.
- Cloud and SaaS services generally reduce the infrastructure needed inside companies.
- DevOps are reinventing networking in the their own way. For example, instead of load balancers/ADC they built open source projects such as Istio and Traefik to avoid the hassle of dealing with vendors that don’t operate the way they need.
- Convergence means that you don’t have to assemble your own network in the DC anymore. Maybe a touch up or advice from an outside expert a couple of times a year.
- SD-WAN means that outsourced WAN management might actually work well enough to be liveable.
- Security moving into the application reduces the need for mitigation skills in firewalls.
- SDN reduces the complexity of owning networks. Common operational tasks like code upgrades and configuration need less time to implement.
