I've updated it to "virtual private network" instead.
You're never going to please everyone, but I think that might be confused with a VPN.
Amazon simply describes it as a "virtual network"
I think just expanding it would be more helpful. I had seen the term before and knew exactly what a Virtual Private Cloud was once being reminded what VPC actually stood for.
I had to look it up, even though I'd seen the term before I had forgotten its meaning.
