It does not take that long

When some overly enthusiastic SDN neophyte or sysadmin-turned-devops-engineer tells me about how long it used to take to create a VLAN and how quick it can be done with new magic SDN controller or automation tool of the day, I have to assume that this person does not really know what she or he is talking about.
What takes long time is change control procedure and no amount of automation or SDN is going to change it.
Since we are talking about VLANs here, in modern data center network you do not need to create a VLAN on more than one switch.
