That Duplex Dark Fiber with DWDM can run 4TBPS of capacity at 100GE (40x 100GE). Each 100GE transceiver costs $2-4K NRC dependent on manufacturer - $160K NRC for 40x. (There are higher densities as well, like 200/400/800GE, 100GE is just getting cheap.)
In AWS, utilizing 1x100GE will cost you >$1MM MRC. For significantly less than that, let's say absolutely worst-case 5K MRC + 200K NRC, you can get 40x100GE.
Now you have extra money for 4x redundancy, fancy routers, over-spec'd servers, world-class talent, and maybe a yacht if your heart desires.
- bobbob1921 2y agoI’m just throwing out a hypothetical, so I may be completely off base: perhaps aws charges high inter-AZ bandwidth prices to keep users from tunneling traffic between availabilities zones to arbitrage lower Internet/egress costs at AZ 1 vs AZ 3. Outside of my statement above, I do agree that the cost Amazon pays for bandwidth between their sites, has to be practically nothing at their scale/size (and thus they should charge their customers very little for it, especially considering easy-multi AZ is a big differentiator for cloud vs self-hosting / colo). The user above’s dark fiber MRC prices are spot on.
