Too Long; Didn't Read
WordPress is one of the most popular CMSs. It’s easy to install and easy to use, but its advantages are also disadvantages because the page generation can be really resource-demanding and WordPress is not only one of the most popular but also one of the most vulnerable systems. Amazon CloudFront is a Content Delivery Network. A worldwide distributed cache system. When a user tries to access your content through CloudFront, the system routes the request to the nearest edge server which serves the content if it exists on it or asks it from your WordPress server. By using it, resource consumption of your site will be extremely low because CloudFront asks for the content only once and serves it million times if needed. You can handle extremely high traffic with millions of users by using only a micro instance for your WordPress!
