What is a CDN? & How to Use It ?

Do you remember how live streams were before CDN? Jittery, sluggish, and sometimes even frustrating. Today’s audience isn’t willing to wait for loading times, as they expect instant streaming. With CDN boosting web performance, it paves the way for the highest streaming quality, delivering stutter-free streams to viewers’ devices at their convenience.

If you want to deliver a flawless, smooth streaming experience, make CDN’s reduce latency your priority in enhancing your web presence.

Check out our blog to explore how CDN improves website performance and  make your live stream a reliable source of content delivery. Discover why people are praising CDN as the best solution for optimizing stream speed and efficiency!

What Is CDN?

CDN (Content Delivery Network)  is a cluster of network  servers interconnected and distributed across geographies for delivering and storing high-quality streams without buffers or lags to end-users, irrespective of their location. 

Usually, CDNs cache the content from the server, meaning, they temporarily store the file so that when a user requests content from the origin server, the server closest to the user location responds. 

This way, the end user need not wait for delivery thus minimizing latency, improving quality, and even reducing server loads.

How Does CDN Work?

Before we see how a CDN works, we must know the fact that a content delivery network is responsible for distributing not only large-sized media files, but also text, images, videos, and other data.

Clear with the above part? If yes, then we will head onto how CDNs work:

1. It starts from a user request when a client sends out a call to view a web page or content.

2. This request is initially passed to the main server or the origin server where the content is hosted.

3. Then, the content is cached by the nearest edge server in a CDN and distributed to the user.  A CDN consists of several interconnected edge servers

4. If needed, an edge server can distribute content by requesting from other edge servers.

5. Once content is cached, the file remains in the edge server to make it available for the next user.

With this understanding of how a content delivery network works, you can make sure that your live stream lets viewers experience a seamless streaming with reduced loading times, improved higher bandwidth, and ultra-low latency by accurately balancing server loads.

CDNs security are also secure against piracy and protect your streams from DDoS attacks.

Therefore, considering this option can help you decide on using live streaming as your content delivery method.

What are the Types of CDN?

If you ask users or website visitors this question, they wouldn’t know because for them it hardly matters. Because, all they require is stability, performance, and security.

Whereas, choosing the right type of CDNs stands as a crucial element for webmasters because it is them who are going to make it functional. And the  types are:

1. P2P CDN

• This type of CDN is mainly used by large corporations and NGOs for content distribution.
• Here, caching is not done, because end users who are watching the live stream share it with others.
• Plus, it requires less equipment and computing power making it possible to share a part of the stream with other end users.

2. Push CDN

• Webmasters mostly prefer this CDN methodology where they manually push the content from the origin server to CDN servers.
• The edge servers will always have a copy of the website content so when users request, they are distributed instantly.

3. Pull CDN

• Here, the CDN servers pull the website content from the origin server once the request is issued.
• And caches it in their memory till the content is expired.
• Plus, webmasters rewrite URLs to look in such a way that content is directly distributed from CDN servers.

So these were the three major types of CDNs that are used by developers. Now we will see why a CDN is much sought after by businesses around.

What are the Advantages of Using CDN?

From live-streaming services to cloud developers to gaming solutions to several e-commerce websites, many of them are relying on content delivery networks. Why? It is due to the perks it offers like:

• Offers faster load times thus giving an exceptional user experience
• Rewards e-commerce sites with stronger engagements, higher views, and lower site retrievals
• Reduces bandwidth costs consumption, and latency
• Optimizes the performance of the site triggering a spike in traffic-adherence level

And there are more. So, if you agree with us in opting for a CDN for your project, then it’s high time we see how to find the right one. 

How to Search for the Right CDN to Use?

Several factors need to be considered before choosing a CDN.

• Check how the traffic is from your live streams and where your audiences reside.
