The Top bill is post optimizations. The bottom bill is pre. You can see that the top bill has .77 Million writes and the bottom had .36 so the top is more than double the Traffic, (2.53 Gigs out, 1.2 Gigs out) but the price is less than half. $3.05 vs $7.79. That's 5x savings. I believe edge cache is free, and we got about 50% cache hits on that, so by getting everything lined up we are at 1/10th the price of pre-optimizations.
Can Every app achieve these numbers? Probably not. But just remember that I'm not a super dumb guy, likely my code didn't suck too hard to begin with, and that if I can save 90% on my bill you should be able to save some on yours by doing the Cache Headers, The Move to 2.7 and Thread Safe. (unless you are on java the I have no clue what optimizations you do after getting your cache headers right) I suspect I can get the price even lower through more optimizations to my DataStore write operations. I am shooting for another 50%. Counting cache hits, serving 5Gig for $3 still makes CDNInABox.com more expensive than large solutions for large sites, but $.60 a gig is not bad for small and medium especially since there is no 80/20 on the peak calculation.
