What is a content delivery network?

A Content Delivery Network, also known as a Content Distribution Network or simply CDN, is a collection of global servers that caches and delivers content such as JavaScript files, videos and images. When you request a web page for example, content on that page is delivered by the closest server rather than the origin server, thereby hastening loading time.

Benefits of Having a Content Delivery Network

CDN Management software dynamically calculates the distance from the nearest server to the requesting client and delivers content based on those calculations. This comes with a host of benefits, including:

CDNs improve page loading time causing almost instantaneous page loads. Of course, businesses, especially online ones, could experience increase in sales due to this.

File Mirroring

CDNs provide you with file mirroring abilities that protect data in case natural disasters happen and affect certain areas of the Internet.

Probably the best reason to consider using a CDN for your small business website is to improve your customer’s experience in terms of speed. Ensuring consistent experience for your customers is important.

  • Faster Load Times: By caching your content across multiple servers worldwide, users access data from the closest server. This setup drastically reduces content delivery and loading times.
  • Reduced Bandwidth Costs: CDNs optimize and compress files, leading to significant savings in bandwidth costs. This means less data is transferred, reducing your expenses.
  • Enhanced Website Resilience: With a CDN, traffic is distributed across multiple servers. This distribution reduces the risk of your primary server crashing during high-traffic moments or DDoS attacks.
  • Improved SEO Rankings: Faster websites often rank better in search engines. A CDN can boost your website’s speed, potentially improving your search result positioning.
  • Global Reach: A CDN allows for efficient catering to a global audience. Regardless of user location, your website will provide fast load times, promoting user engagement and potentially higher sales.

Choosing a Content Delivery Network

There are a number of private or internet-based networks. Some integrate with online video platforms, enhancing video content distribution. However, before you settle on a network, find out if:

High Definition Support

In today’s digital age, consumers expect high-quality visuals. Therefore, when choosing a Content Delivery Network (CDN), it’s essential to ensure it supports high-definition videos. Offering HD videos not only meets audience expectations but can also give your content an edge over competitors, enhancing user experience.

Mobile Delivery

Analytics Availability

Understanding your audience’s behavior is crucial for content optimization. Opt for a CDN that provides comprehensive analytics on content delivery. This will equip you with insights into which content performs best, peak viewing times, user demographics, and more, guiding future content strategies.

Digital Rights Management

For businesses dealing with licensed or protected materials like Pay-Per-View events, digital rights management (DRM) is non-negotiable. A robust DRM system ensures that your content is only accessible to authorized users, safeguarding against potential revenue losses and copyright infringements.

Integration with Video Platforms

If you’re in the realm of video content distribution, consider a CDN that integrates seamlessly with online video platforms. This synergy can streamline your content distribution processes, ensuring videos are delivered efficiently and reach your target audience in optimal quality.


Business owners can use CDN services to speed up delivery times of files, images and other media, increase customer loyalty and improve their search rankings. The service is a little bit costlier than single-server hosting, but the benefits make it worthwhile.

It is important for businesses to note that search engines penalize websites that take too long to load, so optimizing your site by using CDN services should improve your site’s performance overall.

  2. Is this more of a website, software or hosting? CDN is quite a new term for me.
