In a rapidly changing world, your website’s performance is more than just a technical requirement—it supports and drives your business in the digital space.

An underrated factor that can help improve on website speed and security is a Content Delivery Network (CDN). CDN is a group of interconnected servers spread geographically. It helps web content to travel across the end users quickly and efficiently.

In this blog, we have covered everything about CDNs, including their functionalities and the numerous benefits they bring to your website. Read on to learn more!

What is a CDN?

A Content Delivery Network (CDN) is a global network of servers that caches (stores) web content files in its data center. Whenever a website visitor visits, the CDN delivers the content from the nearest server.

Imagine ordering a pizza. Instead of going miles away to give your order to the factory outlet, you can go to the nearest franchise and get your order. A CDN also works that way, allowing businesses to reduce the loading time and improve their website performance.

With so much information overload online, having a CDN is a must to manage the delivery of content.

Speaking of delivery, CDNs can deliver two content types – static and dynamic.

  • Static assets include images, files, videos, web pages, brand logos, and sometimes even entire websites.
  • Dynamic content is the one that keeps on changing as per user behaviour, linkings, preferences, and location factors. For example, OTT streaming platforms like Netflix work in major countries but are banned in China.

How Does a CDN Work?

Now that you have a brief idea of what is a CDN, here is a step-by-step guide on how a CDN functions:

Step 1: Caching Content

CDNs strategically place the edge server near the end user location. The edge servers make copies of your website’s files. While many confuse it with web hosting, these servers just temporarily store the files.

Step 2: User Requesting For Content

Whenever a user visits your website to request content, a CDN server first performs user location detection. This is to minimise the latency period for the content.

Step 3: Delivering Content To End User

After getting the content request from the user, the edge servers check if it has a copy of the requested content. This can lead to two situations:

  • When the content is cached

In this case, it is pretty simple: the server will deliver the stored content from the closest server to the visitor.

  • When the content is not cached

If the content is missed out on caching, the CDN fetches it from the origin server and then delivers it to the end user. It also saves a copy of that content for future requests. 

5 Unavoidable Benefits of Using a CDN

The following are five key benefits a website can reap by using a CDN:

Improve Your Website Speed

The average loading time of websites for mobile is 7-8 seconds and 4 seconds for desktop. This period is crucial, as the user can bounce back if the loading time is high. Four seconds is all it takes for almost 40% of visitors to hit the back button if your website doesn’t load within that time frame. A CDN reduces load times through optimised data delivery.

Enhance Data Security

Data breaches are common these days, making security a top concern. That is when a content delivery network comes in. It

  • Protects against DDoS attacks
  • Prevents the server from getting overwhelmed with traffic
  • Encrypts Data to be cached
  • Scale Without Limits

Nothing stays the same, even the internet. Servers can crash or go down. With CDN, your website keeps operating even at peak traffic times without slowing down. How? Because CDNs distribute traffic evenly across multiple servers.

Expand Your Global Footprint

The best part about CDN is that it stores your content on servers worldwide. This ensures fast delivery to users regardless of location, expanding your website’s accessibility and strengthening your global presence.

Maximise User Experience

Lastly, which user would like easy and quick access to information? CDN makes this a reality by offering a smooth and secure browsing experience globally.

How To Choose the Right CDN Provider?

CDNs are an important SEO tool in every sector, from e-commerce and media to the education sector. While some, like Netflix, have their own in-house content delivery networks, most websites and brands rely on external CDN providers.

Therefore, choosing the right CDN provider is crucial as it can impact your website’s SEO performance, load speed, and traffic.

Consider these factors before making a decision:

  • Server Coverage and Speed: Choose a provider with a wide network of servers to ensure fast content delivery worldwide.

  • Pricing and Scalability: Every website has a different audience and different needs. A popular CDN provider can work for a big media house but may not fit your budget. Therefore, look for a provider like Crazy Domains that offers:
    • Flexible pricing Options

Wrapping Things Up on CDN

That said, investing in a content delivery network can be a game changer for your website. It offers fast loading speeds for content worldwide

If your business lacks the money and resources to build an in-house network, you can outsource it to a CDN provider.

While doing that, always check for important factors. Is the provider fast and secure? Can it grow with your business? And, of course, does the pricing fit your budget?
