That's not why <cloud provider> networking is so much more expensive than a VPS provider... All of the big providers have fairly serious networking investments (and I think it's fair and honest to say that Google's is the largest) that provide a network quality and performance you won't match with any VPS provider. Do you want to stream more than 100 Gbps during the Olympics to people all over the world? Don't try that on OVH, DO, etc. but you can do it on us. We (Google) in fact charge more than AWS for our networking because of our massive global network.

tl;dr: you get what you pay for, and you don't always need our crazy network!
