To make your WordPress website faster, as well as more secure and robust, then using a content delivery network (CDN) is one option available to you.

Cdn reduces loading times

CDN services consist of a network of servers that have been optimized for distributing static files.

CDN services will have servers located all over the globe, instead of just in one or two data centers. As your static files are duplicated to all of these servers, no matter where your website visitors are located, there is likely to be a server relatively close by.
