If you still want to use some AWS services, you can get an AWS Direct Connect fiber cross connect from your data center rack to AWS, just like you do with your Internet connections. They operate Direct Connect in lots of third party carrier-neutral data centers. AWS egress over Direct Connect is $0.02/GB instead of $0.09/GB over the public Internet. You can serve customers through your unmetered Internet connections while accessing S3 (or whatever) via Direct Connect on the backend.
I can pay overpriced cross-connect rates in giant name brand datacenters, with or without terminating one end at Direct Connect. (AFAICT the $1600/mo or so for 10Gbps doesn’t actually cover the cost of the cross-connect.)
But that extra $65k/mo to fully utilize the link is utterly and completely nuts. My mind boggles when someone calls that a good deal. I can buy and fully depreciate the equipment needed to utilize that in a couple of days. (Well, I can’t actually buy equipment on the AWS end, but I can _rent_ it, from AWS, for a lot less money than $64k/mo.)
And I don’t believe at all that it costs AWS anything close to this much to operate the thing. I can, after all, send 10Gbps between two EC2 instances (or between S3 and EC2) for a lot less money.
That $65k is simply a punitive charge IMO. AWS wants me to avoid paying it by not doing this or, in cases where I can’t avoid it (e.g. the thing is actually a link to my office or a factory or whatever) to collect as much money as they can without driving me off AWS entirely.
i'm a customer of the GCP equivalent: partner interconnect. our DC is in an equinix facility, they wire up drops for us that layer 3 straight into GCP. unmetered 1Gbps for about 250 bucks a month per (paid to EQX not GCP). are AWS really charging you per Gb for data egress from AWS into your own DC over an AWS direct connect??
I'm not familiar with GCP but this page below seems basically identical to AWS Direct Connect's pricing structure, including $0.02/GB for egress. Are you sure nobody is paying egress on your behalf?
