How to use a Live Streaming CDN? [Benefits and Provider Reviews]

Are you a video creator who produces content for online distribution via multiple channels or a business involved in live streaming?

If so, you know how important it is to get your content in front of your audience without ruining the viewing experience. What is the best way to get your video content to your viewers?

In this article, we will look into one of the best solutions for this – A CDN for live streaming.

1. What is a CDN?

A content delivery network or CDN is a technology framework of well-distributed servers across locations used to transfer different forms of content quickly and in a cost-effective way.

CDNs are primarily designed to solve the problem of latency.

Latency is the lag that happens when you give a load command to a web page and when the page actually loads. CDN helps to remove the congestion of traffic that results from delivering live streams with a single server.

For example, consider Amazon’s fast delivery. A CDN also works the same manner. When you live stream from a CDN, the closest server attempts to deliver it. The nearest server will have the media files cached or will transfer the request to the next server.

Live streaming CDN leverages a big network of strategically placed servers located in different parts of the world to distribute content more quickly. When the stream is broadcasted, it is populated across the globe.

When a viewer wants to watch the stream, the CDN chooses the closest server and delivers it to the user. Once it is cached on a local server, the media files stay ready for the next viewer in the same location.

If you have a small audience base and your geographic scale is limited, you don’t really need a CDN.

You can stream to your audience from a single server. However, if you have a vast user base with more viewers tuning in to your live streams from different parts of the world, a CDN is essential for you to deliver a top-quality viewing experience to your users.

2. What are the Benefits of Live Streaming CDN?

By connecting multiple servers, a CDN creates a powerful network that shortens the time taken to deliver live streams to viewers. Sharing the load across a server network also improves scalability.

In short, CDN removes the potential latency within a server and the viewer and maximizes the quality of live video streaming.

Some of the benefits of CDN include:

2.1 Speed

CDN delivers live streams without any lag. While your local network might slow down the delivery initially, the CDN will avoid any traffic in between, improving the overall speed.

2.2 Scalability

CDN is the quickest and safest way to deliver your content to your wide audience base located anywhere in the world. It can cater to viral viewership spikes and a larger live audience.

2.3 Quality

The best CDN for streaming helps you to attain the best possible video resolution and audio quality by reducing delays and buffering.

2.4 Security

Streaming through a CDN allows you to prevent DDoS attacks that arise when a website is flooded by several attempts of breaching. A redundant CDN with numerous access points offer an extra layer of security.

3. How to access a live streaming CDN?

There are different ways to get access to a live streaming CDN. The easiest way is to get an integrated service from your Internet service providers.

Most ISPs bill for bandwidth, but the best way is to choose reputed live streaming CDN providers to access the CDN via your live streaming platform.

Choose the best platform that suits your requirements and integrate a CDN. This will give more reliability and scalability for your live streaming services.

Do some research and pick the right providers who offer a single service solution. A single live streaming software that offers video hosting, online distribution, CDN access, API access, video players, monetization channels, adaptive bitrate streaming, and more.

Adaptive bitrate technology dynamically adapts to fit the Internet speed and screen size. It provides the best video quality possible regardless of the connection, devices, or software.

Consider asking the following questions to CDN providers to choose the best one.

  • Does the service support VOD host and live streaming?
  • Pricing plans
  • How vast is the network?
  • Does it offer Point-of-Presence (PoP) locations in areas where you have a huge audience base?
  • Any easy way to gain access to a CDN without complex technical configuration.

Assess the above-discussed elements when comparing CDNs to find the one that fulfills all your requirements.

Now you know what a CDN is and why you need one. However, what to look for in a CDN when choosing one.

It’s great to consider the following factors when choosing a CDN.

4.1 The total number of servers in the network

A good live streaming CDN will have a large number of servers in the network. The size of the server network is directly linked to the speed and scalability. The more servers, the more bandwidth the network can handle.

4.2 Geographical distribution of servers

Distribution of servers is another significant element to look for. CDN’s work via PoP. It simply refers to edge servers in the network that delivers content to the users.

If the distance between a user and the nearest PoP server is less, it helps in offering the best streaming experience. Not all CDN’s have a huge distribution of servers. Ensure that you choose a CDN that has a wide global distribution of servers and it covers the geographic regions that have your major viewers.

4.3 Live streaming features

The next important element to consider is the live streaming features of a CDN. Some CDNs offer a broad range of live streaming features compared to others. For example, with some CDNs, it will be easy and fast to launch as many live streams you want simultaneously.

4.4 Performance

Another important feature of a CDN is its performance. The speed of a CDN is related to size and various other factors. Hence, it is difficult to assess the speed of a CDN directly since it varies with circumstances.

However, you analyze the average performance to get an idea about its speed. Having a fast CDN is particularly important for live streaming, as you want to avoid buffering issues as much as possible.

4.5 Analytics

The Best CDN for streaming offers you detailed analytics of your live stream. For example, it gives data like the number of views, location with the most participation, and other related info. These analytics serves as a great marketing tool to understand the effectiveness of your live streaming efforts.

4.6 Pricing

When it comes to pricing, several factors influence the price plans of CDNs. For example, the geographical location of your audience, volume, etc. also plays a significant role in determining how much you must pay for your CDN.

If you get a large number of views and your content goes viral often, chances are that CDN providers might charge you higher. However, there are peer-peer CDNs also that come with standard pricing regardless of your traffic volumes.

4.7 Security

If you broadcast sensitive content, you must consider choosing a CDN that offers powerful security systems. Choose a CDN that offers industry-leading security features and expertise to meet your needs. Secure CDN systems ensure online interactions leverage the top levels of trust and security.
