When it comes to cost, the article is wrong. What you do is get a quote from all the CDNs (akamai, fastly, cloudfront) and talk to your AM in the CDN you want about matching the other guy(s).<p>Our CF cost is .02/GB, no region delta, no request costs, for like a $2k commitment a month.
It always boils down to where your customer is. If you're targeting a specific geo, it always pays to check what CDN provider has better peering/transit to the majority of the customers. There's also lots of regional players with way better connections compared to global CDN providers.<p>Price-wise, public prices are just for checking out the provider, one-off engagements or for using it as a secondary/backup-only CDN. Every CDN provider have private pricing and when there's a baseline usage it's always worthy reaching out. A small commitment can really drop the data transfer prices.
