Have the fastest website

How does it work?

The main goal of the CDN is to reduce latency - the time between submitting a request and a page fully loading on a device, by reducing the physical distance the request has to travel. For example, a user from the US wants to view the content that originates from a centralized server in the UK. Without CDN, the user would experience poor loading times if the request had to cross the Atlantic.

In opposition to this, CDN stores data in earlier mentioned PoPs. Essentially, CDN places your content in many places at once, providing coverage to all of your users. Not only does it shorten the distance but it also offloads the traffic sent from the original server, resulting in less failures as well as cost-savings for the content provider.


CDN provides a quick transfer of assets, including HTML pages, javascript files, images and videos. The popularity of Content Delivery Networks is growing and the majority of web traffic is served through CDN including traffic from huge websites such as Instagram, Facebook, Netflix, and Amazon. Any site operating on a larger scale needs CDN as well as different types of businesses or organizations such as:

  • Government. Large websites can provide important information to citizens quickly and efficiently using a CDN.
  • E-commerce. CDN is very useful to E-commerce websites during periods of heavy traffic such as Black Friday, holidays etc.
  • Media. Media websites that need to update and deliver up-to-date information can benefit from CDN by updating news, stories and pages in real-time as well as removing old and outdated data.
  • Finance. CDN provides banks and banking institutions with a fast, secure and reliable infrastructure in order to deliver sensitive data to clients.

Other sectors that also benefit from CDN include:

  • Advertising
  • Online gaming
  • Mobile apps
  • Healthcare
  • Technology

Fastest file delivery

High loading speed is of great importance nowadays, when the internet is growing. When we talk about website speed, there are various elements that need to be optimized such as images, videos, apps etc. Having a website with a high loading speed means:

  • Better User Experience
  • Better position in search engines
  • Higher conversion rates - number of visitors who turn to customers for e-commerce websites

On the other hand, researches have shown that long loading times result in users abandoning the website. More precisely, 1 out of 4 customers will abandon a webpage that takes more than 4 seconds to load. In short summary, the faster the website means more people will stick around and stay for longer.

Top benefits of CDN

If you wonder who uses a CDN - pretty much everyone. More than half of the internet traffic is served through CDN today. If you have done pretty much anything online, you have benefited from CDN, whether you knew it or not. These are the reasons why it is a great option:

  • Global access. Content delivery networks help make content globally available by having multiple Points of Presence. Being global is an important step to high-quality.
  • Reduced latency. Large distances between a user requesting web content and the server delivering it can result in greater latency. Content delivery network servers store cached web content closer to your users, resulting in reduced latency and improved performance.
  • Better response to traffic spikes. A holiday, event or increased popularity can lead to a sudden increase in content demand. Content delivery networks use “load balancing” to distribute the demand across servers and prevent a single-server overloading. Load balancing also prevents the spike from impacting website performance. Publishers with large numbers of page views in a short period of time often benefit from this significantly.
  • Data analytics. Most CDN providers include automatic data analytics like: most searched topics, location, time etc. This is useful for companies because it shows which practises work and which do not and it also allows for them to improve their business model.

There are a lot more pros of using CDN such as:

  • Greater user satisfaction
  • Improved content delivery
  • Faster E-commerce
  • Increased reliability and trustworthiness
  • Protection against DDoS attacks
  • Reduced bandwidth costs

CDN Security

Whether your business is big, small or you have your own personal website, it is important to have fast and uninterrupted service. There are many factors that can lead to slow website performance, but a significant one is a sudden spike in traffic. This can be due to legitimate reasons like content-gone-viral, but it can also be a result of a far more malicious action such as a DDoS attack.

CDN and DDoS attacks

A sudden increase in traffic to your website for the purpose of flooding your server and rendering your website unavailable is known as a Distributed Denial of Service or DDoS. The goal of these attacks is to overload the server where your website is hosted - with fake traffic. As it is mentioned already, CDN stores cached data on various servers so users do not have to send requests to the original server. This increases loading speeds but it also presents a great measure of protection from DDoS attacks due to its ability to redistribute traffic when needed.

If your website is a target of a DDoS attack, a lot of traffic from hackers will be directed toward your servers. CDN ensures it does not reach the origin server and render your website unavailable. When a server is hit with more traffic than it can handle, it simply redirects the traffic to other servers. There will be no downtime, and your users should not notice a thing.

It does not take much downtime to make a negative impact on a website. CDN ensures your website is always online, functional and well-performing and users associate it with reliability and professionalism. Finally, one of the most important reasons to use CDN is peace of mind. When you use CDN you can rest assured that your website is safe, secure, well-performing and always online.

CDN Cost efficiency

Content delivery networks eliminate having to pay for expensive foreign services and for multiple providers. Content distributed through CDNs is available globally with the help of just a single provider. It also reduces the cost of transferring data because it is located between users and the origin server, cutting down on traffic between the hosting server and the rest of the internet.

Reduce bandwidth costs

CDNs serve cached content so that the origin server does not have to deliver the content over and over. Web hosting companies’ charges vary, according to the amount of data that is transferred from or to the origin server. This data transfer is usually called “bandwidth”. However if most of a website’s content is cached through CDN servers, far less data needs to be transferred to or from the host server, which results in lower bandwidth costs.

Most CDNs charge for their services, but the savings on monthly data transfer costs usually outweigh the cost of using the CDN.
