There\u2019s also the possibility that your readers are coming from one continent only: be it America, Europe, Asia, Oceania, or Africa, they still have to cross very long distances to reach your origin server!<\/p><p>Every time a website aims to reach a wide international audience, its distance from the origin server is one of the critical factors of web performance.<\/p><p>So, if your server is in New York, but your readers are from San Francisco, New Delhi, or Melbourne, how can you decrease the distance and allow all of them to benefit from your content at a similar speed?<\/p><p>In this article, we\u2019re going to answer these questions, and explore the magic world of CDNs: a bridge that makes users closer to the websites they\u2019re visiting, no matter where they are in the globe!<\/p><h2 class=\"wp-block-heading\">What Is a Content Delivery Network (CDN)?<\/h2><p>The acronym CDN stands for <em>Content Delivery Network<\/em>: a CDN establishes a globally distributed network of edge servers between your website\u2019s origin server and your visitors\u2019 location. <\/p><p>Once the content of your site passes through them for the first time, the edge servers keep a copy of the static content (images, CSS, and JavaScript files) and then deliver it to the end-users, allowing them to access the content a lot faster.<\/p><p>Every HTTP request made by your users will be served from the nearest location possible, no matter where they\u2019re geographically located.&nbsp;<\/p><h3 class=\"wp-block-heading\">How Does a CDN Work?<\/h3><p>Let\u2019s say the server hosting your website content (the origin server) is located in Madrid, but you receive many visits from people in Buenos Aires.<\/p><p>Every time one of your Argentinian users requests a page, all the assets contained in it have to travel from Buenos Aires to Madrid. Then the server has to send the assets back to the user in Buenos Aires. Quite a ride, isn\u2019t it?<\/p><figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"469\" src=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/from-madrid-to-buenos-aires.jpg\" alt=\"Google Maps: from Buenos Aires to Madrid\" class=\"wp-image-1311099\" srcset=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/from-madrid-to-buenos-aires.jpg 800w, https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/from-madrid-to-buenos-aires-300x176.jpg 300w, https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/from-madrid-to-buenos-aires-768x450.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Source:<a href=\"https:\/\/www.google.com\/maps\"> Google Maps<\/a><\/figcaption><\/figure><p>Contrary to the image above, this is not a \u201ddirect flight\u201d for your static content: during their journey from Spain to Argentina, they also have to travel through a series of routers along the way.<\/p><p>Each router has to process the request.<\/p><p>So every time an Argentinian visitor wants to access your website, two factors are affecting the amount of time (latency) needed for the request to be finalized:<\/p><ul class=\"wp-block-list\"><li>The total distance from Buenos Aires to Madrid<\/li>\n\n<li>The time it takes for each router on the way to process the request<\/li><\/ul><p>The same thing happens when the origin server receives the request, and respond to the users, sending them back the content they asked to receive.<\/p><p>This round trip is measured in milliseconds and is called RTT (<em>round trip time<\/em>).<\/p><h4 class=\"wp-block-heading\">The primary goal of the CDN is to reduce latency and RTT.<\/h4><p>Since the CDN is made by a globally distributed network of servers, every time your Argentinian visitors ask for your content, they won\u2019t receive it from Spain.&nbsp;<\/p><p>The edge servers composing the CDN distributed network already have a cached version of the content of your website: whenever a user requests it, they can provide it quickly and securely.<\/p><p>In this way, round trip time is reduced, because the CDN may have different edge servers in South America, which are way closer than Madrid!<\/p><p>Take the image below as a reference: <\/p><figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"343\" src=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/CDN-Network-examples.png\" alt=\"How Does a CDN Work?\" class=\"wp-image-1311105\" srcset=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/CDN-Network-examples.png 800w, https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/CDN-Network-examples-300x129.png 300w, https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/CDN-Network-examples-768x329.png 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Credits: Kanoha, Own work &#8211; <a rel=\"noreferrer noopener\" href=\"https:\/\/creativecommons.org\/licenses\/by-sa\/3.0\/\" target=\"_blank\">CC BY-SA 3.0<\/a><\/figcaption><\/figure><p>On the left, all end-users are receiving content from the same server: the website requested by the user will be accessible only after every HTTP request is transmitted from the central location.<\/p><p>On the right, the same content is now delivered through different edge servers, linked to the origin one.

All the files must be reachable via HTTP requests.<\/p><h4 class=\"wp-block-heading\">What Is a Push Zone?<\/h4><p>A \u201cpush\u201d zone (or \u201cpush CDN\u201d) does not import any files automatically, but your site has to upload (push) them to the CDN. Once the files are pushed, the zone will be synchronized with the edge servers of the network. <\/p><p>We can think of a push zone as <strong>a sort of repository to store content<\/strong>.&nbsp;<\/p><p>A push zone is the ideal solution if you\u2019re serving big resources, such as large file archives, software updates, or any other file larger than 10MB. It can also be useful if you serve files that are not keen to change, like PDF documents, image galleries, etc.<\/p><h3 class=\"wp-block-heading\">Why Do the URLs of Static Files Change When the CDN Is Active?<\/h3><p>Without a CDN, the URL path of your static files would be similar to:<\/p><code>href=\"http:\/\/yourdomain.com\/wp-content\/uploads\/image.jpg<\/code><p>But when you enable the CDN, they change and become something like:<\/p><code>https:\/\/cdnzonename-cdn.com\/wp-content\/uploads\/image.jpg<\/code><p>where the first level domain <em>cdnzonename-cdn.com<\/em> is the CNAME provided by your CDN service (so it may vary belonging to the CDN you\u2019re using, and it can usually be customized).<\/p><p>This happens because the static files are not coming from your origin server anymore: a third-party server is loading them, and this is proof that the CDN network is now taking care of the delivery of your static assets.<\/p><h3 class=\"wp-block-heading\">Should You Use a CDN or Not?<\/h3><p>If your website is intended to receive a lot of visits from locations far from your server, adopting a CDN is a fundamental step to implement in your web performance optimization strategy. <\/p><p>So, yes, you should use it.<\/p><div id=\"om-jbyojf9wimyywstllxy9-holder\"><\/div>\n\t<script>(function (d, u, ac) {\n\t\t\tvar s = d.createElement('script')\n\t\t\ts.type = 'text\/javascript'\n\t\t\ts.src = 'https:\/\/a.omappapi.com\/app\/js\/api.min.js'\n\t\t\ts.async = true\n\t\t\ts.dataset.user = u\n\t\t\ts.dataset.campaign = ac\n\t\t\td.getElementsByTagName('head')[0].appendChild(s)\n\t\t})(document, 20440, 'jbyojf9wimyywstllxy9')<\/script><h2 class=\"wp-block-heading\">What Are the Benefits of Using a CDN for a WordPress Site?<\/h2><p>We already introduced some of the benefits that come with the adoption of a CDN service: <strong>applying a second layer of caching and reducing latency and RTT above all<\/strong>.<\/p><p>But three other factors make a CDN very profitable for your web optimization strategy. Let\u2019s see them in detail:&nbsp;<\/p><h3 class=\"wp-block-heading\">1. CDNs Reduce Time to First Byte (TTFB)<\/h3><p><a href=\"https:\/\/wp-rocket.me\/google-core-web-vitals-wordpress\/reduce-ttfb-server-response-times\/\">Time to First Byte<\/a> indicates the response time of a server.<\/p><p>It measures the amount of time needed by a server to load the HTML of a website so that the client can start rendering the page.<\/p><p>Simply speaking, it is the time your end-users have to wait before the page they requested starts displaying on their browsers.<\/p><p>Network latency is one of the elements that contributes to increasing Time to First Byte (along with other factors such as server configuration, server performance, and DNS response time).<\/p><p>As we saw, when a CDN is enabled, static content will be cached by the edge server, reducing latency.<\/p><p>As a logical consequence, then, CDNs can contribute to decreasing Time to First Byte. <\/p><p>For more info about the techniques, you can use to reduce TTFB, read our guide <a href=\"https:\/\/wp-rocket.me\/google-core-web-vitals-wordpress\/reduce-ttfb-server-response-times\/\">How to Reduce Time to First Byte and Load Your WordPress Site Faster.<\/a><\/p><h3 class=\"wp-block-heading\">2. CDNs Reduce Bandwidth Costs<\/h3><p>Bandwidth is the amount of data transferred and downloaded from your website.<\/p><p>Hosting providers offer you a predetermined bandwidth that is included in your plan.<\/p><p>CDNs can decrease bandwidth costs because they reduce the burden on your hosting system: since your static content is cached through the CDN, your origin server won\u2019t have to transfer those data to your end-users.<\/p><p>The final effect is that <strong>CDNs reduce the traffic passing through your origin serve<\/strong>r, and avoid the additional cost of bandwidth charges from your hosting.<\/p><h3 class=\"wp-block-heading\">3. CDNs Add a Security Layer to Your Site<\/h3><p>According to the last <a href=\"https:\/\/www.nexusguard.com\">NexusGuard report<\/a>, during the first half of 2018 the increase in the size of DDoS attacks was quite scary: around 500% more than last year!<\/p><p><a href=\"https:\/\/www.cloudflare.com\/learning\/ddos\/what-is-a-ddos-attack\/\">Distributed denial-of-service (DDoS) attacks<\/a> are malicious attempts to overwhelm the capacity of the target server by flooding it with multiple simultaneous external requests. These attacks are like a massive traffic jam collapsing a highway, where the targeted server is the congested road which ends up being unavailable.<\/p><figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"536\" src=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/Chapa_traffic_jam_in_Maputo.jpeg\" alt=\"Traffic Jam in Maputo\" class=\"wp-image-1311111\" srcset=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/Chapa_traffic_jam_in_Maputo.jpeg 800w, https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/Chapa_traffic_jam_in_Maputo-300x201.jpeg 300w, https:\/\/wp-rocket.me\/wp-content\/uploads\/1\/Chapa_traffic_jam_in_Maputo-768x515.jpeg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Credits: <a href=\"https:\/\/www.flickr.com\/photos\/95731954@N02\/9717216968\">Verdade on Flickr<\/a> &#8211; licensed under cc-by-2.0<\/figcaption><\/figure><p>Because of its position on the edge of your network, a CDN acts as a protection against this type of attack and other security threats for your origin server. This happens because<strong> the saturation provoked by the attack is processed on different machines, and it won\u2019t reach the hosting server<\/strong> which remains up and available.<\/p><p>This is valid also for any other situation where traffic spikes could make your website suffer: the increased content availability is a plus that your users will appreciate.<\/p><h3 class=\"wp-block-heading\">So, Is a CDN Beneficial Also for SEO?<\/h3><p>If you think that Google loves fast and secure websites, we can indeed confirm that enabling a CDN on your site is also beneficial for SEO and the PageSpeed Insights performance score.

If you\u2019re out of the GCP, you can\u2019t use their CDN, because they don\u2019t support external origins.<\/p><p>Google Cloud CDN prices depend on the usage you make of it, as described in <a href=\"https:\/\/cloud.google.com\/cdn\/pricing\">their pricing sheet<\/a>.&nbsp;&nbsp;<\/p><h3 class=\"wp-block-heading\"><a href=\"https:\/\/rocketcdn.me\/\">RocketCDN<\/a><\/h3><p>Lastly, RocketCDN is our premium optimized CDN with a dedicated CNAME. We directly integrated it into WP Rocket, thanks to the Bunny CDN API.<\/p><p>We chose Bunny CDN as the backbone of our custom CDN service. That means you will get all the same benefits, 120+ edge locations where your website files will be copied.<\/p><h3 class=\"wp-block-heading\">What is the Difference Between Bunny CDN and RocketCDN?<\/h3><p>Unlike Bunny CDN, though, RocketCDN does not charge you depending on your consumption. Instead, you&#8217;ll pay a set monthly fee of <strong>$7.99 per site for unlimited bandwidth<\/strong>, providing your website with faster speeds and reduced server load at a reasonable cost.<\/p><p>If you noticed, it&#8217;s uncommon to find a CDN that provides unlimited bandwidth, so there are no overage fees if you choose RocketCDN as your CDN solution.<\/p><p>Other <a href=\"https:\/\/rocketcdn.me\/benefits-cdn\/\">RocketCDN features and benefits<\/a> include the following:<\/p><ul class=\"wp-block-list\"><li>No technical knowledge is ever required&nbsp;<\/li>\n\n<li>Global reach and a faster-delivered content<\/li>\n\n<li>Reduce network latency<\/li>\n\n<li>SEO performance and user experience improved<\/li>\n\n<li>Improve reliability thanks to redundancy<\/li>\n\n<li>Reduce DDoS attacks&nbsp;<\/li>\n\n<li>Compatible with other CMS platforms, not just for WordPress<\/li>\n\n<li>All CDN files automatically served over HTTPS<\/li>\n\n<li>SSL Traffic included<\/li><\/ul><h3 class=\"wp-block-heading\">The Benefits of Using RocketCDN and WP Rocket<\/h3><p>As a WP Rocket customer, you can directly activate your CDN subscription from your dashboard. This means you don\u2019t need to look for an external CDN provider.<\/p><p>Both WP Rocket and RocketCDN work out of the box. Our settings are super simple for anyone even for complete beginners, which is a very important feature of both of our products.&nbsp;<\/p><p>Most other products will provide you with a plethora of customization options that may be useful for sophisticated users but are useless for common users.&nbsp;<\/p><p>Despite having one of the simplest interfaces, both do not skimp on crucial functionality. Everything is done in the backend and some features aren\u2019t even offered by other solutions.<\/p><p>For example, RocketCDN automatically populates all of its data centers with files. Even Cloudflare does not auto-populate its data centers, so more users are sent uncached sites, resulting in slower speeds for those people.<\/p><p>Using both WP Rocket and RocketCDN can be the perfect solution for getting the best speed out of your WordPress website.<\/p><p>You may also use it with or without WP Rocket plugin. You do not need to be a WP Rocket customer to utilize RocketCDN.<\/p><p><a href=\"https:\/\/www.youtube.com\/watch?v=LtU76BZcRQk&amp;feature=emb_logo\">See our quick video tutorial about RocketCDN.<\/a><\/p><h3 class=\"wp-block-heading\">How to Use RocketCDN with WP Rocket<\/h3><p>Because creating a Bunny CDN instance in numerous locations takes expert-level knowledge, the significant benefit of using RocketCDN is that it allows for simple one-click setup within the WP Rocket dashboard.<\/p><p>If you are not &#8220;tech-savvy,&#8221; this is an excellent option. Setting up a CDN isn&#8217;t difficult, but if you&#8217;ve never done it before, it might be frightening. As a result, the ease of setup is an extra bonus.<\/p><p>If you use RocketCDN without WP Rocket, all you have to do is buy a plan, acquire an API key, install the plugin, and input the key.<\/p><p>If you use WP Rocket, you can subscribe to the service directly from the CDN tab in WP Rocket. It will automatically create your unique rocketcdn.me CNAME.<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"1159\" src=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/2022\/04\/WP-Rocket-\u2039-crazycoffeecrave-com-\u2014-WordPress-1-1.png\" alt=\"WPRocket &amp; RocketCDN integration settings\" class=\"wp-image-4274071\" srcset=\"https:\/\/wp-rocket.me\/wp-content\/uploads\/2022\/04\/WP-Rocket-\u2039-crazycoffeecrave-com-\u2014-WordPress-1-1.png 1600w, https:\/\/wp-rocket.me\/wp-content\/uploads\/2022\/04\/WP-Rocket-\u2039-crazycoffeecrave-com-\u2014-WordPress-1-1-269x195.png 269w, https:\/\/wp-rocket.me\/wp-content\/uploads\/2022\/04\/WP-Rocket-\u2039-crazycoffeecrave-com-\u2014-WordPress-1-1-768x556.png 768w, https:\/\/wp-rocket.me\/wp-content\/uploads\/2022\/04\/WP-Rocket-\u2039-crazycoffeecrave-com-\u2014-WordPress-1-1-83x60.png 83w, https:\/\/wp-rocket.me\/wp-content\/uploads\/2022\/04\/WP-Rocket-\u2039-crazycoffeecrave-com-\u2014-WordPress-1-1-124x90.png 124w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><\/figure><p>Then, it will automatically configure optimal performance settings for assets served from the CDN.
