The Future of Networking: SD-WAN and Automation
"Networking is dying" is a headline that resells itself every few years. It is wrong — but the job is changing. The engineer who only knows the CLI is being squeezed; the engineer who understands packets and can automate is more valuable than ever. Here is what is actually happening.
SD-WAN moved intelligence into software
SD-WAN abstracted the underlay. Path selection, policy, and failover that used to be hand-configured per device are now driven centrally by software. That does not remove the need for networking knowledge — when an SD-WAN tunnel misbehaves, you still have to read the packets to find out why.
Automation replaced repetitive config
Pushing the same VLAN to 200 switches by hand is gone. Tools like Ansible, Netmiko, and NAPALM do it in seconds. The skill that matters now is describing intent and validating outcomes — not typing the same command 200 times.
Why packets still matter
Here is the part the "hardware is dead" crowd misses: automation and SD-WAN sit on top of packets. When something breaks at 2 a.m., no controller dashboard will tell you why a particular flow is being dropped — a packet capture will. Deep fundamentals are what make an automation engineer trustworthy.
The skill stack for the next five years
- Rock-solid fundamentals via CCNA and CCNP — taught at packet level.
- Python for networking — start with Python network automation (Netmiko, NAPALM, Ansible).
- Linux comfort — see Linux for networking.
- A NetDevOps mindset — combine all three in the DevNet Associate track.
The future belongs to engineers who can both read a packet and write a script. Build both.
