That's also an over-simplification. For example at AWS you can get a fully bidirectional 10gbps link, regardless of what other tenants are doing on the network

That's also an over-simplification. For example at AWS you can get a fully bidirectional 10gbps link, regardless of what other tenants are doing on the network. Nobody else that I'm aware of can match that. And you'll quickly find that 20TB of bandwidth at those network speeds are nothing, you can cross into petabytes without breaking a sweat (1 petabyte at 50% of bandwidth 24x7 for a month for just one server.) At that kind of network volume bandwidth costs dominate everything (about $65K for an petabyte of bandwidth at Amazon.) I challenge you to beat that anywhere. Also if you have bursty traffic patterns, AWS comes out a lot cheaper because it's designed around quickly scaling up and down capacity. In the end it depends on matching a provider to your particular needs because they vary wildy in strengths and weaknesses and costs.
