The CDN enables the fast delivery of web content by reducing the distance between visitors and origin servers.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_does_a_Content_Delivery_Network_Work\"><\/span><strong>How does a Content Delivery Network Work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">When a user makes an initial request for static website assets, a CDN server is responsible for transferring the files from the origin server.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Simultaneously, it caches a copy of these assets in the server nearest <strong>(known as the edge server)<\/strong> to the user. This cached data is then utilized for subsequent requests, enabling the CDN to deliver site content to visitors more rapidly and alleviate the workload on the web server.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For instance, if a visitor is located in India and the origin server is in the United States, the content delivery may experience delays due to the physical distance between them. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">To mitigate this, employing a CDN with servers strategically positioned in locations like Singapore, Australia, and the United States ensures swift delivery of web files to the Indian visitor.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this scenario, the CDN distributes the content from the server in Singapore, minimizing the delivery time by selecting the nearest server available.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_does_CDN_improve_page_speed_in_a_static_website\"><\/span><strong>How does CDN improve page speed in a static website?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Content Delivery Networks (CDNs) contribute to page performance in the following ways:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reducing network round-trip latency<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Serving cached content and minimizing the load on your server<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Optimizing the content<\/span><\/li>\n<\/ul>\n<p><b>Reducing Network Round-Trip Latency: <\/b><span style=\"font-weight: 400;\">CDNs minimize network round-trip latency by leveraging a global infrastructure.\u00a0<\/span><span style=\"font-weight: 400;\">The distance data has to travel affects the time it takes to reach users.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">CDNs, through strategically placed edge servers around the world, significantly reduce round-trip times, often bringing them down to just a few milliseconds. This improvement is crucial, especially considering that network round trips over long distances can take hundreds of milliseconds.<\/span><\/p>\n<p><b style=\"font-style: inherit;\">Serving Cached Content and Reducing Server Load:<\/b><span style=\"font-weight: 400;\"> CDNs enhance performance by serving cached content and lessening the load on the origin server. When an edge node receives content with caching enabled, it stores that content for future use.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Subsequent requests for the same resource can then be fulfilled directly from the edge node, bypassing the origin server. This caching mechanism not only accelerates content delivery but also reduces the overall load on the origin server, leading to quicker responses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Additionally, CDNs often offer protection against Denial of Service (DoS) attacks. They are equipped to handle a large number of requests efficiently, preventing overwhelming the server during such attacks.<\/span><\/p>\n<p><b style=\"font-style: inherit;\">Automatically Optimizing Content:<\/b><span style=\"font-weight: 400;\"> CDNs frequently provide options to automatically optimize content fetched from the origin server before delivering it to end users.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For instance, if the origin server provides a large PNG image file but the user&#8217;s browser supports the more modern WebP format, the CDN can automatically convert the image to WebP. This optimization not only saves bandwidth but also enables faster loading of the image for the visitor.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some CDNs go beyond basic optimizations and offer advanced features, such as automatically loading low-priority JavaScript code asynchronously. These optimizations contribute to a more efficient and faster user experience.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Steps_to_host_and_optimize_your_static_website_using_CDN\"><\/span><strong>Steps to host and optimize your static website using CDN<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">During this laboratory session, you will acquire the skills to host a static website on a Cloud Storage Bucket and optimize its performance using a Content Delivery Network (CDN).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To utilize the CDN, access the <\/span><a href=\"https:\/\/www.whizlabs.com\/labs\/\" target=\"_blank\" rel=\"noopener\">Whizlabs hands-on labs<\/a> <span style=\"font-weight: 400;\">page.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Note that a premium subscription is required for lab access.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the lab&#8217;s page, use the search bar to find and select the lab titled &#8220;<\/span><a href=\"https:\/\/www.whizlabs.com\/labs\/hosting-a-static-website-on-cloud-storage-bucket-and-optimizing-your-website-using-cdn\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Hosting a Static Website using CDN<\/span><\/a><span style=\"font-weight: 400;\">&#8221;\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This lab is designed to be interactive and provides step-by-step instructions within the lab details, guiding you through the process of hosting and optimizing the static website.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To host the website in <\/span><a href=\"https:\/\/www.whizlabs.com\/google-cloud-certifications\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Google Cloud<\/span><\/a><span style=\"font-weight: 400;\">, you must sign in to the Google Cloud Platform (GCP) console by following the below instructions:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Visit the Google Sign-In page.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Paste your Email ID and click Next.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Enter your Password and click Next.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Accept Google Cloud Terms of Service by checking the agreement and clicking Agree and Continue.<\/span><\/li>\n<\/ul>\n<p><b>Select Project<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">From the top bar, click the dropdown to select the project.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Choose the listed project and click on it.<\/span><\/li>\n<\/ul>\n<p><em><span style=\"font-weight: 400;\">Note: If you&#8217;ve completed a lab, sign out before starting a new one.

This drastically reduces bandwidth usage on servers and optimizes content delivery by routing client requests to edge CDN servers.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Consequently, this decreases the load on origin servers, serving data at a lower frequency.<\/span><\/p>\n<p><b>Lower Latency for Improved User Experience<\/b><\/p>\n<p><span style=\"font-weight: 400;\">For geographically dispersed user bases, CDNs decrease latency by caching static assets on edge servers closer to users. This proximity reduces the distance between users and static content, leading to quicker content delivery, improved page load speeds, and an enhanced overall user experience.<\/span><\/p>\n<p><b>Manage Traffic Spikes and Avoid Downtime<\/b><\/p>\n<p><span style=\"font-weight: 400;\">CDNs can handle high traffic spikes effectively by load-balancing requests across a distributed edge server network.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By offloading and caching static content, CDNs allow websites to accommodate a larger number of simultaneous users without overburdening the existing infrastructure. This helps prevent unplanned outages and downtime, particularly for websites with a single origin server.<\/span><\/p>\n<p><b>Reduce Costs<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Serving static content constitutes a significant portion of bandwidth usage. Offloading these assets onto a CDN can substantially reduce monthly infrastructure expenses. Beyond cutting bandwidth costs, CDNs decrease server costs by alleviating the load on origin servers, enabling existing infrastructure to scale efficiently.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some CDN providers also offer fixed-price monthly billing, providing stability and predictability to recurring expenses.<\/span><\/p>\n<p><b>Increase Security<\/b><\/p>\n<p><span style=\"font-weight: 400;\">CDNs play a crucial role in DDoS attack mitigation. Many CDN providers offer features to monitor and filter requests to edge servers.
