Want to take your online business to the next level? Don’t underestimate the potential of Content Delivery Networks (CDNs)!

Read on to know more about Content Delivery Networks (CDNs)

What is a Content Delivery Network (CDN)?

CDNs back most of our interaction on the internet. Whether you’re reading blogs, news, shopping online, or doing almost anything, CDNs play an invisible yet important role.

But, how?

Content Delivery Networks (CDNs) facilitate content delivery on the internet. Contrary to a normal web host, the CDNs store a copy of your website’s content in multiple servers among various geographical locations.

Suppose, you operate an eCommerce platform from Mumbai, but your users are from all over the world.

If a person from California is willing to access your website, this might signal your server in Mumbai. However, because of the vast geographical distance, the website might load slowly.

Overall, because of this slow performance, your business might suffer from high bounce rates and your sales might also get affected.

CDN lets the user from California access your website within a few seconds through a local CDN server.

This way, CDN helps you to diversify your data on different servers to improve loading speed and avoid service failure.

So, who should use CDNs?

Content Delivery Networks can be used by almost every website owner. Bloggers, eCommerce stores, advertisement, media, online gaming, government, distance educational institutions, and more can leverage the power of CDNs.

Top 6 Astounding Benefits of CDN 

Escalates Site Loading Speed

One of the primary tasks of CDN is to reduce latency and thereby improve the site’s loading speed. In the simplest sense, latency refers to the time delay between requesting data from the server and getting it. Latency can occur for many reasons; however, geographical distance plays an important role in this process.

But, how does CDN reduce latency?

CDNs store a cached version of a website on numerous servers (known as Points of Presence) in different geographical locations. Thus, when a user in California tries to check your Mumbai-based website, a local US PoP can access the data for that person.

In short, by saving your web content on various servers, CDN ensures quick loading, reduces latency, and decreases the load of data on servers.

Improves Connectivity and Scalability of Websites

A regular web host works as a data shelter for your website. Unfortunately, it does not attempt to improve the website’s efficiency and speed.

On the other hand, CDNs ensure a quality experience for every user. Unlike usual web hosts, with CDNs, a huge array of users can access your website simultaneously. It manages high traffic flow and aims to improve the user experience.

Moreover, CDNs work 24/7 uninterrupted. In ordinary website hosting, when the server malfunctions, your business suffers a loss too. However, CDNs work even if your actual server is facing some error. In this case, the CDN will use the cached content of your website and ensure smooth running.

A Boon for Search Engine Optimization (SEO)

CDN plays a crucial role in improving the search engine ranking of websites.

The search engine, Google, made it clear that the sites with the fastest loading speed have higher chances of ranking on their SERP. As CDN escalates the site’s loading speed, it also improves your web’s chances of ranking high.

Moreover, image optimization and website security also play a major role in SEO. With CDN, you can ensure the best quality images to suit every device. Since almost every CDN provider offers malware protection, you can keep the scammers at bay and your website healthy and secure for ranking.

Enhances Website’s Security

Cybercrimes have become a matter of concern these days. With the increase in internet malpractices, the threat of being hacked by scammers looms over the head of every online business.

However, CDNs act as a protective fence on the thresholds of your server. It blocks hackers, scammers, or any other outside threat preventing them from getting inside your website.

With strong analytics and automation tools, Content Delivery Networks block DDoS attacks, firewalls, and other internet scams from entering your website.

Improves the Quality of Content

Imagine you’re watching an important video or listening to your favorite music/podcast and suddenly it starts buffering. Or suppose, you’re in an important online meeting and you experience poor audio quality and slow transmission.

We all hate to be in that position, don’t we? Poor content quality spoils our experience and mood. However, with CDN, you can not only improve the speed of delivery but also the quality of content delivered.

By distributing the content on various sources, CDNs strike the load-balance of traffic and improve the user experience.

Boosts eCommerce Websites’ Performance

In today’s internet era, people cherish prompt website performance. Especially in the eCommerce segment, customers expect a fast loading speed of images, prompt payment system, and an overall swift user experience.

CDNs are the best choice to improve the performance of your eCommerce website. It allows B2B and B2C retailers to deliver quick content, control and manage panels, diversify the website traffic and ensure large-scale availability of their business.

How Does CDN Work?

A CDN acts as a network of servers with the goal to deliver fast, reliable, and secure content. The primary aim of CDNs is to minimize the distance between user and server and thereby reduce latency.

Let’s demystify how CDN works!

CDNs store a cached version of a website’s content in multiple servers across the globe (a.k.a Points of Presence). These PoP servers handle prompt content delivery to users within their geographical proximity. For instance, a user in Canada can easily access your UK-hosted website through a local Canadian PoP.

In short, by distributing the data on multiple servers a CDN reduces traffic load, ensures quick content delivery, and offers other major benefits to the businesses.

Advantages of CDN Against Web Host

A traditional web host possesses the actual data of the website while a CDN stores a cached version of that data on multiple servers. Though CDN cannot replace the need for actual web hosting, it can accelerate the growth of the website and improve web performance.

With a regular web host, your website might have to bear the consequences of network failure and server failure. However, with CDNs, you can ensure the smooth working of your website (even during bouts of technical glitches).

Overall, CDNs can reduce the pain points of using traditional web hosting and help you to achieve your business goals!
