Your website looks stunning but hey something is awfully wrong; it takes ages to load! Patience is undoubtedly a virtue but mind you, never dare to test the patience of your users.

Faster website speed is key to ensure better user experience! Hence, a slow website is detrimental to your business for it creates negative perception.

There could be many ways to enhance the speed of your website; one such is making the network carry the load.


Yes, you guessed it right! In this post, am going to tell you about Content Delivery Network (CDN).
  • What is a CDN?
  • How it works?
  • What are the advantages of using a CDN?

Let’s get started!


What is a CDN?

CDN, also known as Content Distribution Network, is basically a network of proxy servers distributed across various geographical locations called points of presence (PoPs).  

CDNs are widely used to reduce latency, i.e., the delay that occurs from the moment you request a web page and its content actually appears on your screen.


The delay duration is caused by many factors, the prominent one being the physical distance between you device location and the hosting server of the website.

The aim of a CDN is to cut down that physical distance virtually in order to achieve improved website rendering speed and performance.

 

How does a CDN work?


To reduce the distance between the server of a website and its user, CDN stores a cached version of the static content of a website such as CSS/JS files, images and other structural components in multiple geographical locations or PoPs.

Each PoP contains a number of CDN nodes or edge servers as shown in the figure.


When a user tries to access the content of a website, most of the page load time is spent in retrieving the static content. In CDN, the static content or building blocks of a website are provided to as many server nodes as possible, distributed throughout the globe.

For instance, when a user from London accesses a US-hosted website, the node closest in proximity to the user i.e., a local UK PoP will deliver the static content to the user. Thus, data will be delivered via the shortest possible distance (minimized latency) and a fastest site experience will be ensured.

Advantages of using CDN

In the era of mobile and app-based internet, more and more businesses such as ecommerce owners, advertising agencies, online gaming companies, etc. are forced to improve user experience by reducing the page load time.

In this fast-paced world just a second of delay can result into more than 5 percent loss in customer conversions. And here comes a CDN as an indispensable solution!

The usage of CDN is soaring by 20 percent every year and it speaks volumes about its benefits. I think its true value will be revealed in the near future; however, here are some of the key advantages:

Empowers global reach

CDNs have enabled businesses to cater to worldwide audiences by eliminating frictions in long-distance online transactions. Thus, it has allowed making a stride towards making internet-driven business safe. Now you can reach out to more than 34 percent of the global population that thrives online.

Minimizes latency

The latency issue has been efficiently dealt with CDN as service providers usually place node servers at popular geographies across the world. Now, with CDN information can be sent and received within no time and users love it.

Localized data centres

With CDNs international users and to be specific inter-continental users of your website are no longer required to take trans-continental electronic hops while accessing your web content. Thanks to the localized data centres provided by most of the CDNs which result in faster downloads.

Lower network loads

Many websites slow down during peak hours due to the increased number of users consuming resources on a server thus increasing network loads. The higher the network loads the lower the performance.

In CDN, however, visitors are redirected to edge servers and thus network load is balanced resulting into less network disruptions. This in turn translates into better user experience and higher conversion.

Enhanced performance and reliability

When you deliver HD quality videos and maintain high quality service at the same time, it is likely to increase customer satisfaction. In fact, to make everything faster and increase the performance and reliability of all the content within their system is the objective of a CDN.

Valuable analytical insights

Commercial CDNs usually charge per byte and therefore provide you with file usage reports. These reports along with your own website analytics report can offer you better insight regarding each single penny spent. Additionally you can improve your performance by digging a bit more into the performance metrics.

Reduced overhead costs

CDNs are just perfect for SMEs with tight budgets. It enables you to cater to audience across regions via a single cost-effective platform. Thus, it eliminates the need to pay for expensive foreign hosting and thus reduce overhead costs.

Protection against DDoS

Last year, the news of DDoS attacks had hit headlines frequently and the impact was really devastating. These attacks negatively impact the reputation of a company in addition to inflicting huge economic losses.

Any DDoS attack impacting your data centre would be combated by cloud solutions designed to tackle an attack prior to reaching your data.
