During peak hours this can place heavy stress on an under-powered server environment, leading to slow performance or potentially downtime. Since the rise of widespread residential and commercial broadband adoption internationally, numerous solutions had been found to mitigate or prevent this issue entirely.<\/p>\n<p>On one end of the spectrum is the website\u00a0<a href=\"http:\/\/craigslist.org\/\" target=\"_blank\" rel=\"noopener\">Craigslist.org<\/a>\u00a0which is hugely popular in terms of US-based traffic, but the website itself is extremely lightweight to minimize memory and bandwidth usage. In contrast, top 50 websites like\u00a0<a href=\"https:\/\/www.reddit.com\/\" target=\"_blank\" rel=\"noopener\">Reddit<\/a>\u00a0and\u00a0<a href=\"http:\/\/imgur.com\/\" target=\"_blank\" rel=\"noopener\">Imgur<\/a>\u00a0regularly go offline as a result of their massive popularity. Whether the downtime is a result of a specific traffic spike, malicious attack or website configuration issues, the result is almost universally negative. Everyone knows it is imperative that the website&#8217;s performance is guaranteed.\u00a0To make sure that a website continues to perform well under load we can distribute static website content to multiple servers across the globe. With the use of a reliable content delivery network (CDN) many traditional hosting concerns are eliminated. In this post I will address the less technical aspects of CDNs and provide some basic use case examples.<\/p>\n<\/div><\/section><\/div><div class='av-flex-placeholder'><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_third-f12765db1ad5165e82cc2ea1174c53da\">\n.avia_transform .flex_column.av-av_one_third-f12765db1ad5165e82cc2ea1174c53da{\nanimation-duration:0.5s;\n}\n<\/style>\n<div  class='flex_column av-av_one_third-f12765db1ad5165e82cc2ea1174c53da av_one_third  avia-builder-el-6  el_after_av_two_third  avia-builder-el-last  flex_column_table_cell av-equal-height-column av-align-middle av-animated-generic fade-in  '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkafd3ts-816b0f4af136fba1cd4fe511ab980190\">\n.avia-image-container.av-lkafd3ts-816b0f4af136fba1cd4fe511ab980190 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lkafd3ts-816b0f4af136fba1cd4fe511ab980190 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lkafd3ts-816b0f4af136fba1cd4fe511ab980190 av-styling-no-styling avia-align-center  avia-builder-el-7  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-478 avia-img-lazy-loading-not-478 avia_image ' src=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/down.jpg\" alt='' title='Servers Busy'  height=\"350\" width=\"458\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/down.jpg 458w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/down-300x229.jpg 300w\" sizes=\"(max-width: 458px) 100vw, 458px\" \/><\/div><\/div><\/div><\/div><\/div><!--close column table wrapper.

In principal the smaller the distance between the visitor and the server, the faster the content will be transferred to the user. Specifically, the lower the latency between the web server and the user the better. A CDN gives us the ability to intelligently shift traffic in a more efficient manner. Since we cannot control a users location or internet connection speed, its the responsibility of the admin to do everything possible from the server side. So, we try to connect them to the closest possible server without the user ever noticing the network shift.<\/p>\n<p>A reason why I encourage the use of a CDN is the guarantee of nearly constant up time.\u00a0If your primary server is offline for a technical issue with your hosting provider, the static content will remain temporarily visible on the CDN infrastructure. Depending on the website configuration it&#8217;s possible that small downtime on your master server may actually go completely unnoticed to the outside world. This is perfect for religious, political and social organizations which may become subject to a distributed\u00a0denial-of-service (DDoS) attack. Since you do not have a single server or IP address than can be easily overwhelmed, the likelihood of a low level attack taking down your site is virtually eliminated.<\/p>\n<\/div><\/section><\/div>\n<\/p>\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_5'  class='avia-section av-lkaed097-0ac480908592576cbe5d5c8b36d03d57 alternate_color avia-section-default avia-no-border-styling  avia-builder-el-16  el_after_av_section  el_before_av_section  avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-59'><div class='entry-content-wrapper clearfix'>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-3ebqz-b2caf41cd37f24a0d83d15ab7cc879fe\">\n.avia_transform .flex_column.av-3ebqz-b2caf41cd37f24a0d83d15ab7cc879fe{\nanimation-duration:0.5s;\n}\n<\/style>\n<div  class='flex_column av-3ebqz-b2caf41cd37f24a0d83d15ab7cc879fe av_one_full  avia-builder-el-17  avia-builder-el-no-sibling  first flex_column_div av-animated-generic fade-in  '     ><section  class='av_textblock_section av-lkaecct9-b2d2b0a26e9bdae3e249f0e7ce256374 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2><strong>Why Should You Use a CDN?<\/strong><\/h2>\n<ul>\n<li><strong>Location aware:<\/strong>\u00a0By using a CDN, visitors can automatically fetch content such as images, heavy scripts, and video from a nearby server.\u00a0You can imagine that it takes longer for a visitor from Europe to load an image off a server based in the United States than it takes for a local. By keeping a cached copy of the static content on a site closer to the visitor, the page will be more quickly displayed.<\/li>\n<li><strong>Faster routing:<\/strong>\u00a0Usually the network connections between a visitor and the web server go through the path of least resistance.\u00a0However, this is not necessarily be the fastest possible route.\u00a0CDN providers often choose slightly more expensive but faster routes over the internet.\u00a0Compare it with a toll road.\u00a0You pay for it, but it is generally the superior option.<\/li>\n<li><strong>Constant availability:<\/strong>\u00a0The design of a CDN with multiple servers in different locations is much more resilient than a traditional website which is subject to downtime due to a single piece of equipment failure.<\/li>\n<li><strong>Less (primary) load:<\/strong>\u00a0Since copies of the content are stored on other servers, your primary web server does not always have a large number of clients to host.\u00a0This means that you can technically continue to run a shared or virtual private server (VPS) as a low cost master, and have the bulk of the work performed by a separate CDN service. More RAM, processing power, and faster drives will certainly help, but you can get by without them to test the advantages before migrating.<\/li>\n<\/ul>\n<\/div><\/section><\/div><\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_6'  class='avia-section av-lkaee8tj-09849dea014f22da14ec86b8bb0f7175 main_color avia-section-default avia-no-border-styling  avia-builder-el-19  el_after_av_section  el_before_av_section  avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-59'><div class='entry-content-wrapper clearfix'>\n<div class='flex_column_table av-2uwob-0ad30eda2d933d9f25e7656e5b81b54a sc-av_two_third av-equal-height-column-flextable'>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-2uwob-0ad30eda2d933d9f25e7656e5b81b54a\">\n.avia_transform .flex_column.av-2uwob-0ad30eda2d933d9f25e7656e5b81b54a{\nanimation-duration:0.5s;\n}\n<\/style>\n<div  class='flex_column av-2uwob-0ad30eda2d933d9f25e7656e5b81b54a av_two_third  avia-builder-el-20  el_before_av_one_third  avia-builder-el-first  first flex_column_table_cell av-equal-height-column av-align-middle av-animated-generic fade-in  '     ><section  class='av_textblock_section av-lkaedaol-e6c6b128159e45f2d8eec11a1714af88 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2><strong>What Are The Possible Downsides?<\/strong><\/h2>\n<p>There are a few drawbacks to using a CDN.

After all, it takes massive infrastructure for all those dispersed servers and a lot of power to keep the hardware running 24\/7.<\/p>\n<p>I often see a hybrid solution, where the CDN is mainly used for clunky assets and the actual HTML content is directly pushed by the master web server. In the source code you will see a different domains for the specific assets, such as\u00a0d1abcdef8.cloudfront.net.\u00a0This works well as an intermediate step for small or growing websites that don&#8217;t expect to see massive traffic bumps.\u00a0<strong>This combination leaves you more susceptible to downtime when something on your website goes viral.<\/strong>\u00a0Still, the CDN can present vast improvement for website load time and availability across the board.<\/p>\n<\/div><\/section><\/div><div class='av-flex-placeholder'><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_third-f12765db1ad5165e82cc2ea1174c53da\">\n.avia_transform .flex_column.av-av_one_third-f12765db1ad5165e82cc2ea1174c53da{\nanimation-duration:0.5s;\n}\n<\/style>\n<div  class='flex_column av-av_one_third-f12765db1ad5165e82cc2ea1174c53da av_one_third  avia-builder-el-22  el_after_av_two_third  avia-builder-el-last  flex_column_table_cell av-equal-height-column av-align-middle av-animated-generic fade-in  '     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkafgm8r-cb05191ad11cb0bb3d9ccc9c6beceac7\">\n.avia-image-container.av-lkafgm8r-cb05191ad11cb0bb3d9ccc9c6beceac7 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lkafgm8r-cb05191ad11cb0bb3d9ccc9c6beceac7 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lkafgm8r-cb05191ad11cb0bb3d9ccc9c6beceac7 av-styling-no-styling avia-align-center  avia-builder-el-23  el_before_av_hr  avia-builder-el-first '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-480 avia-img-lazy-loading-not-480 avia_image ' src=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn2.png\" alt='' title='Content Delivery Network'  height=\"439\" width=\"1138\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn2.png 1138w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn2-300x116.png 300w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn2-1030x397.png 1030w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn2-768x296.png 768w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn2-705x272.png 705w\" sizes=\"(max-width: 1138px) 100vw, 1138px\" \/><\/div><\/div><\/div><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkafjauu-27c0699759c46395353fbbe9b6590d87\">\n#top .hr.hr-invisible.av-lkafjauu-27c0699759c46395353fbbe9b6590d87{\nheight:20px;\n}\n<\/style>\n<div  class='hr av-lkafjauu-27c0699759c46395353fbbe9b6590d87 hr-invisible  avia-builder-el-24  el_after_av_image  el_before_av_image '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkafjhed-1e2b87f80c0bfb49a6c3b1a3fa6830fe\">\n.avia-image-container.av-lkafjhed-1e2b87f80c0bfb49a6c3b1a3fa6830fe img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lkafjhed-1e2b87f80c0bfb49a6c3b1a3fa6830fe .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lkafjhed-1e2b87f80c0bfb49a6c3b1a3fa6830fe av-styling-no-styling avia-align-center  avia-builder-el-25  el_after_av_hr  avia-builder-el-last '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-481 avia-img-lazy-loading-not-481 avia_image ' src=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn6-1030x371.png\" alt='' title='Content Delivery Network'  height=\"371\" width=\"1030\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn6-1030x371.png 1030w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn6-300x108.png 300w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn6-768x277.png 768w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn6-705x254.png 705w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2023\/07\/cdn6.png 1038w\" sizes=\"(max-width: 1030px) 100vw, 1030px\" \/><\/div><\/div><\/div><\/p><\/div><\/div><!--close column table wrapper.

If your website receives views from abroad then a caching or CDN solution will definitely help expand those markets. An\u00a0<a href=\"https:\/\/aws.amazon.com\/s3\/\" target=\"_blank\" rel=\"noopener\">Amazon S3<\/a>\u00a0storage solution or purpose built WordPress host like\u00a0<a href=\"https:\/\/wpengine.com\/\" target=\"_blank\" rel=\"noopener\">WPengine<\/a>\u00a0will be worth considering<em>.<\/em><\/p>\n<p><strong>Scenario 2: Getting media attention and unexpected social network traffic.<\/strong><br \/>\nIf your web server cannot keep up with a sudden rush of simultaneous sessions it may go temporarily offline at the worst possible time. A caching and CDN solution will definitely help out.<\/p>\n<p><strong>Scenario 3:\u00a0Your issue attracts unwarranted negative attention.<\/strong><br \/>\nNo matter what issues you cover, it&#8217;s possible to become subject to a variety of online attacks. Spam and trolling are common and can be defeated easily. However it takes more planning to prevent a sophisticated attacker from taking down your single web server. A scalable CDN offering will negate a disruptive attack and the pricing adjusts based on need.<\/p>\n<p><strong>Scenario 4: Planning for future website growth.<\/strong><br \/>\nIf you&#8217;re seeing rapid viewer growth it makes sense to take a proactive approach for serving those people. WordPress sites can be converted to a rudimentary CDN in minutes with plugins so now is the time to try it out if you haven&#8217;t before.<\/p>\n<\/div><\/section><\/div>\n<\/p>\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_8'  class='avia-section av-lkaeec78-e0b3cc0d8a2fd98eb334fa87363f2873 main_color avia-section-default avia-no-border-styling  avia-builder-el-29  el_after_av_section  el_before_av_button_big  avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-59'><div class='entry-content-wrapper clearfix'>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-q8sr-9bfd2cdcd60d5f9f6312606dae6ad7af\">\n.avia_transform .flex_column.av-q8sr-9bfd2cdcd60d5f9f6312606dae6ad7af{\nanimation-duration:0.5s;\n}\n<\/style>\n<div  class='flex_column av-q8sr-9bfd2cdcd60d5f9f6312606dae6ad7af av_two_third  avia-builder-el-30  el_before_av_one_third  avia-builder-el-first  first flex_column_div av-animated-generic fade-in  '     ><section  class='av_textblock_section av-lkaedtsi-236e4325d5b07cdba9fac47ae242f366 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2><strong>What About Search Engine Ranking Benefits?<\/strong><\/h2>\n<p>Google has made it official that the speed of your website is an important factor for determining page ranking.\u00a0It is only natural that users prefer to visit a faster site compared to a slow one. Immediate direct results of a faster website are longer visitor sessions plus a higher conversion rate. Since competition for volunteers and donation is so fierce online, it&#8217;s important to show up first when someone is researching your issue.<\/p>\n<p>CDN as a service is rapidly gaining in popularity. This is partly because numerous big players now offer reasonable fees and fast deployment across a variety of web platforms. In my experience CDNs may improve your load times and the overall availability of your website, but the cost-benefit to small sites is limited.\u00a0For enterprise customers, this will increasingly be the standard implementation moving forward.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_third-f12765db1ad5165e82cc2ea1174c53da\">\n.avia_transform .flex_column.av-av_one_third-f12765db1ad5165e82cc2ea1174c53da{\nanimation-duration:0.5s;\n}\n<\/style>\n<div  class='flex_column av-av_one_third-f12765db1ad5165e82cc2ea1174c53da av_one_third  avia-builder-el-32  el_after_av_two_third  avia-builder-el-last  flex_column_div av-animated-generic fade-in  '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkafafzb-8e3492f1c6dd9eb013eddbf0236d1b9e\">\n.avia-image-container.av-lkafafzb-8e3492f1c6dd9eb013eddbf0236d1b9e img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lkafafzb-8e3492f1c6dd9eb013eddbf0236d1b9e .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lkafafzb-8e3492f1c6dd9eb013eddbf0236d1b9e av-styling-no-styling avia-align-center  avia-builder-el-33  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-837 avia-img-lazy-loading-not-837 avia_image ' src=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2016\/05\/Google.webp\" alt='' title='Google'  height=\"683\" width=\"1024\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/zacmaybury.com\/wp-content\/uploads\/2016\/05\/Google.webp 1024w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2016\/05\/Google-300x200.webp 300w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2016\/05\/Google-768x512.webp 768w, https:\/\/zacmaybury.com\/wp-content\/uploads\/2016\/05\/Google-705x470.webp 705w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/div><\/div><\/div><\/div><div  class='avia-button-wrap avia-button-center  avia-builder-el-34  el_after_av_section  avia-builder-el-last '>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lk65nh4i-fd4da632665ecd5694ab17f740fac625\">\n#top #wrap_all .avia-button.av-lk65nh4i-fd4da632665ecd5694ab17f740fac625:hover{\ncolor:white;\ntransition:all 0.4s ease-in-out;\n}\n<\/style>\n<a href='https:\/\/zacmaybury.com\/blog\/' class='avia-color-theme-color avia-font-color-theme-color avia-button avia-button-fullwidth av-lk65nh4i-fd4da632665ecd5694ab17f740fac625 avia-icon_select-yes-left-icon avia-color-theme-color'  ><span class='avia_button_icon avia_button_icon_left' aria-hidden='true' data-av_icon='\ue874' data-av_iconfont='entypo-fontello'><\/span><span class='avia_iconbox_title' >Return to Blog<\/span><span class='avia_button_background avia-button avia-button-fullwidth avia-color-theme-color-highlight'><\/span><\/a><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Popular sites generally have a lot of content and many visitors simultaneously.
