CDNs became popular back in the old days, when some people thought that if two websites are using jquery-1.2.3.min.js, CDN could cache it and second site would load quicker. These days, browser don't do that, they'll ignore cached assets from other websites because it somehow helps to protect user privacy and they value privacy over performance in this case.
There are some reasons CDNs might be helpful. Edge capability probably is the most important one. Another reason is that serving lots of static data might be a complicated task for a small website, so it makes sense to offload it to a specialised service. These days, CDNs went beyond static data. They can hide your backend, so public user won't know its address and can't DDoS it. They can handle TLS for you. They can filter bots, tor and people from countries you don't like. All in a few clicks in the dashboard, no need to implement complicated solutions.
But nothing you couldn't write yourself in a few days, really.
Interesting to hear. I suppose then geographical availability while handling cache consistency over the entire world must be a bigger selling point. Offering security with a few clicks of button also seems like a great benefit given a lot of users may not want to engage in best practices. This centralization of security still bothers me though.
