No code programming (end of programmers)

you programmers may laugh, but software defined networking has removed most of the skill from networking and made it all about learning the vendors platform.
**Just try finding a proper routing table in Azure.**

This may grow arms and legs and replace a lot of mainstream programming work.

Uhm, you mean the "Routing Table" that you need to create to do, well, most things involving firewalls and site to site?

I've used a development platform that involves both code, and visual elements you can plumb together to model flow and so on. Actually pretty neat though it is so niche it doesn't save anyone any time as nobody knows how it works.

that's not a proper routing table though.

This is...
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.0.254 192.168.0.88 25
10.125.0.0 255.255.0.0 192.168.0.1 192.168.0.88 25



Try doing global vnet peering, where the VNET in Japan has a gateway subnet, and the VNET in the UK also has a gateway subnet. You can peer them but if you think you can route to your UK data centre from the Japan VNET via the UK gateway forget it. Cos the routing doesn't allow you to do that. Japan VNET objects will use the Japan VNET gateway only.

And don't get me started on service endpoints...


I mean it's all nice, and makes it easier, but if you know how to build a global WAN with Cisco routers, you need to rethink your approach when using software defined networking.
