The first holders of the VCDX certification have now appeared. The initial batch are all VMware employees, as they went through each step of the process when each step was in beta.
One of them was Duncan Epping, a Senior PSO Consultant for VMware in the Netherlands. Duncan was VCDX number 7, and is well-known in the VMware community. He is a regular contributor to the VMware community forums, and runs his own blog, Yellow Bricks.
Duncan has just posted this thoughts on the final element of the VCDX, the Design Defence. This is as much information as I've yet seen around this element, so I thought I'd post it here too.
