Having a well-performing website is crucial for keeping users engaged and staying ahead of the competition. One technology that can help you achieve this is a Content Delivery Network (CDN). But what is a CDN, and should you use one? Here, we share our knowledge on this topic by exploring how CDNs work, their benefits, the setup process, and associated costs to determine if they are necessary for your digital infrastructure.

What is a CDN and What Does it Do?

A CDN is a network of servers located around the world. These servers are designed to efficiently deliver web content, like images, videos, and other static files, to users based on where they are located. By storing and serving content from servers closest to the user, a CDN can significantly improve website speed and overall user experience.

The technology acts as a go-between for your website’s origin server and the end-user. Rather than delivering content straight from your origin server, the CDN stores copies of your website’s static files on its distributed network of servers around the world. When a user requests a file, the CDN automatically provides the content from the nearest available server, reducing delay and ensuring quicker load times.


How to Set up a CDN?

Setting up a CDN is typically a straightforward process:

  • Choose a CDN provider: There are various CDN providers available, such as Cloudflare, Google Cloud, Amazon CloudFront, and Fastly, each with different pricing plans and features.
  • Connect your website or application: Most CDN providers offer simple integration methods, such as adding a CNAME record or modifying your DNS settings to point to the CDN’s servers.
  • Configure caching rules: You can customize caching rules to determine which files should be cached and for how long, ensuring optimal performance and freshness of content.
  • Monitor and optimize: Many paid CDN providers offer analytics and monitoring tools to help you track performance and optimize caching settings for better results.




What are the Benefits of a CDN?

Speed and Load Times for Global Traffic

Using a CDN can improve your website’s speed and performance, especially for visitors from different locations. By serving content from servers near the user, a CDN reduces latency and ensures faster load times. This leads to better user experiences and potentially higher conversion rates.

Protection against DDoS attacks

Content networks, or CDNs, can help shield websites from Distributed Denial of Service (DDoS) attacks. DDoS attacks try to overload servers with excessive traffic, causing downtime or disruptions. CDN providers often have strong security measures and filters to prevent DDoS attacks, keeping your website running and secure.

Other Benefits of Using a CDN

Another advantage of using a CDN is that it can offload content from your main server. By serving static files from the CDN’s servers, you reduce the workload on your own server, improving its performance and ability to handle more traffic.

Additionally, CDNs have multiple locations around the globe, known as Points of Presence (PoPs). This ensures your website remains accessible even if one of the servers goes down, improving overall availability.

CDNs can also enhance the security of your website. They often provide features like SSL/TLS encryption, web application firewalls, and DDoS protection as mentioned, which all helps safeguard your site and users.

How Much Does a CDN Cost?

The cost of a CDN can vary a lot depending on the provider, features, and how much you use it. Many providers have flexible or On-Demand pricing models based on things like how much bandwidth you use, how many requests you make, and how wide the geographical coverage is. It can become a bit complicated.

Cloudflare pricing

Cloudflare offers a free plan with basic CDN features, as well as paid plans with more advanced features and better performance. Some web hosting companies, like Siteground, also include CDN services as part of their hosting packages, which can be a cost-effective solution for website owners.

Should I Use a CDN?

Using a CDN is often advantageous, particularly for websites or apps with a worldwide audience or that serve large volumes of static content. Although there may be instances where the service is not essential, such as for websites with a mainly local user base or those delivering dynamic content that cannot be efficiently cached.

At Phoenix Media, we don’t currently use a CDN for our website. Since our hosting is located in Singapore and the vast majority (99%) of our visitors are from Southeast Asia, the benefits are minimal for our specific needs. Additionally, our hosting provider offers robust security features that make a separate CDN service unnecessary.

However, for businesses targeting a wider global audience or serving resource-intensive content, a CDN can be an extremely helpful tool for improving website performance, security, and overall user experience.
