How to Speed Up a Website With CDN

    It’s important to understand how to speed up a website, because your website’s speed is crucial to succeed online. People don’t like slow loading websites and will abandon it. This can also have a negative impact on your SEO, bounce rates, conversion rate, as well the average time that people spend on your website.

    Your site will be ranked higher on Google and will receive more natural traffic if it loads faster. CDNs can be a powerful tool to speed up your website’s loading time, regardless of who visits it. Today we’ll discuss CDNs, their benefits, and common uses with real-world examples.

    So What is a Content Delivery Network (CDN)?

    To answer the question, how to speed up a website with CDN, we first need to understand the term CDN. A Content Delivery Network (CDN), is a group of servers that are geographically distributed and work together to deliver fast Internet content. A CDN’s primary purpose is to increase web performance by decreasing the time it takes to deliver internet content from a web server to the users.

    The CDN architecture also reduces network latency. Latency refers to the annoying delay between the time you request to load a webpage and the moment it actually appears onscreen.

    CDNs allow for quick transfers of assets required for loading Internet content, including HTML pages, javascript stylesheets, images and videos. CDN services continue to gain popularity. Today, most web traffic comes from CDNs. This includes traffic from major websites like Netflix, Amazon, and Facebook among other.

    A well-designed CDN can also help websites protect themselves against malicious attacks like Distributed Denial of Service (DDOS).

    How do CDNs Work?

    CDNs consist of a collection of servers linked together that have the goal to deliver content as cheaply, quickly, reliably, securely and reliably as possible. CDN works by bringing content closer towards the geographical location of end users. Points of Presence, or PoPs, are strategically located data centers that provide this service. These data centers are located in various parts of the world and include thousands of caching servers, which are used to improve connectivity and speed of content delivery to users.

    CDN providers install their edge servers on IXPs. IXPs are the points where traffic flows among different internet service providers, so data can reach users more quickly. CDN management software automatically calculates which server may be closest to the user, making it possible for the software to deliver content based on these calculations. CDN edge servers communicate with the content origin server to quickly deliver new and cached content. Apart from placing servers in IXPs a CDN optimizes client/server data transfers. CDNs strategically place Data Centers around the globe to improve security and to withstand different types of Internet congestion and failures.

    Content hosted on a CDN server will remain available for some users in the event of an outage or attack. However, it cannot be used as a web host. You still need to use traditional web hosting to run your website. CDN simply holds a cached copy of your website content on servers near your end users. In the event of any updates or changes, it always refers to your main website content.

    CDNs Software and hardware optimizations, such as efficient load-balancing and solid state hard drives (SSDs), help data reach the end users even more quicker. File compression and minification are also used to reduce data transfer times by reducing file sizes. CDNs also improve speed of websites, that are using SSL certificates, by optimizing connection reuse and enabling TLS false start.

    CDNs Pricing

    Although CDNs typically charge for their services however, the monthly data transfer savings will often outweigh the cost. CDN costs can vary depending on the use case. However, getting started can be quite easy or free. Cloudflare, a CDN provider, offers a free tier for those who are just starting out or for personal or hobby projects. The cost of upgrading to Cloudflare Pro tier for additional security features and faster mobile load speeds is only $20 per month.

    The pricing structure for some CDN providers is dynamic, beyond the trial or free tier. Amazon CloudFront for example will charge you different rates for different volumes in different regions, but this is not the case with Cloudflare. This can become complicated quickly and some CDNs may want to work directly on a quote.
