A high-performance POP will considerably enhance the person expertise via the diminished loading time, decrease latency and minimized packet loss.

Outline pull or push zones?

The very first thing to do is to outline zones. Certainly, it’s essential to specify what can be served by the CDN and to decide on whether or not they’re in Push or Pull:

  • Push Zone : Content material can be despatched on to the CDN servers.
  • Pull Zone : The content material is in your server and the CDN copies it.

As soon as the zone has been created, you’ll get hold of a URL of the “lorem-1af.kxcdn.com” sort that you’ll declare to your WordPress.

Personally, I solely use pull zones as a result of I would like my content material to remain on my server. I additionally select to position on the CDN solely the pictures (who’re by far those that eat probably the most). Nonetheless, nothing prevents you from creating a number of zones for a similar web site, one containing the pictures, the opposite the JS and at last the final the CSS.

As proven within the picture under, you may completely function your SSL certificates with a CDN and KeyCdn even gives many settings choices by zone (Token, Gzip, and many others.).
