If it works like this there would only be a few CDNs. A lot of cloud providers have their own CDN variant and here Vultr is filling that gap in their product line.

Even if it's not better it'd make it easier for existing customers to not have to add yet another vendor.

The more CDN providers, the more choices you have for less money. If you are using Vultr as a hosting provider, it's much easier to enable/disable CDN out of the control panel.

I’ve seen some sites use “bunnycdn.ru” is it the same? Does it have any affiliation with Russia?
