Looking at our metrics, we have over a 95% cache hit ratio using CloudFront. We use it to store large JS libraries, think Excel, table plugins, HTML editors, and it works great. It keeps the pressure off our origin app server and we version each release of the vendor code, so it rarely changes. It also helps that our users share the same office space, so its always cached for the 20+ users in the office. The phrase "CDN's are obsolete" is not true, it is not a simple true/false statement but a complicated one. HTTP/2 is not always faster depending on if your link connection has any loss to it (wifi, spotty 4g).
