Top 7 Content Delivery Networks (CDNs) for Live Streaming in 2025

Live streaming has quickly become a popular medium the world over. According to Statista, live streams are the third most popular form of video content consumed worldwide and the most popular non-entertainment video content.

For organizations, live streams have an immense and untapped potential for corporate communication, brand outreach, video marketing, onboarding, and training and learning efforts.

However, the magic of live streams fades fast if viewers encounter buffering or lag. Research shows that more than 50% of viewers abandon live streams within 90 seconds or less if the quality is poor.

Content Delivery Networks (CDNs) are often used to combat buffering and latency issues caused by surging live-stream demands. Their vast network delivers content from geographically distributed servers, keeping your stream smooth for viewers worldwide.

This helps businesses stream all around the world without having to set up a dedicated hardware presence everywhere. It's a cost-effective, hassle-free approach that works for everyone.

Using a CDN alongside your live streaming platform can go a long way to making sure your streaming efforts don't go to waste when start-and-stop annoyances make your viewers switch to other streams or drop off entirely.

But with so many different CDNs out there, how do you know which one is the best pick to suit your live streaming efforts? To answer this question, we'll be looking at the 7 best CDNs that you can choose for your live streaming platform.

Before we begin, however, let's understand what a content delivery network is and how it works.

What are Content Delivery Networks?

Content Delivery Networks or CDNs are a network of servers placed in different regions of the world. These servers take content such as audio, video, images, and more from an origin server and copy it in a cached form.

When users try to access any kind of content, they are directed to their closest CDN rather than the origin server. This helps users access files faster, reduces load on servers, and distributes content globally.

You can think of CDNs as distributors. (In fact, another name for CDNs is Content Distribution Networks.) Instead of having to request something from the source, users can request it from an edge server located nearby.

It's like heading to your nearest bookstore to pick up a copy of a book rather than driving all the way to the publisher. You save yourself the trip, and the publisher doesn't have to worry about having a physical presence in every location—everyone wins.

But there are other benefits, too. Increasing demand for data requires organizations to deploy individual servers worldwide, which isn't practical, feasible, or cost-effective. Because of this, they rely on CDN providers, which already have massive networks of servers deployed globally.

How Content Delivery Networks Work for Live Video

Now that we've covered what content delivery networks are and how they work, we need to understand how they work to deliver live video streaming.

For a video-on-demand (VoD) stream, the process is similar to distributing a webpage, image, or any other content. The edge server copies over the content and caches it so it can be delivered to a user when requested.

The same process can't work for live streams because of the real-time nature of live streaming. If edge servers request the content in its entirety, then it's not live anymore. If users request content from the origin server, then that defeats the purpose of using CDNs.

To solve this problem, CDNs often segment the live stream and cache it to the edge server in chunks. These segments are usually seconds or minutes long and are streamed to the user as soon as their cached. Once a segment is streamed, another one is queued to be cached and streamed.

The entire process follows these steps:

Compression and Encoding

First, the feed from the live camera is encoded using suitable codecs like H.264, H.265, VP9, and AV1. This helps convert raw footage into digital, streamable content and also helps cut down on the file size.

Transcoding

Once the feed is encoded, it is sent to a streaming server that converts the stream into multiple bitrates and resolutions to allow viewers to stream at different quality levels depending on the internet connection.

During this transcoding process, the stream is also chopped up into smaller, manageable chunks, typically a few seconds long.

Manifest File Creation

Next, a manifest file is created to map out all the chunks for the different resolutions and bitrates. This file acts like a roadmap for the video player, listing all the available chunks, the order in which they should be played, and which ones correspond to which quality.

Progressive Delivery

At this stage, the stream is packaged and ready to be sent out using protocols like HLS and DASH. As the live stream starts, the video content delivery network pushes the transcoded segments out to the edge servers closest to the viewers.

Caching

As soon as an edge server receives a segment of the live stream, it caches it locally for a few seconds or minutes. When a new segment is created by the streaming server, it is added next in line to be cached and streamed to the user. Because of the nature of this method, live streams often have a delay of a few seconds to compensate.

Content Delivery

Finally, the live video player on the user's device requests the appropriate segments of the live stream based on the manifest file it received earlier. The segments are downloaded, assembled, and played in the corresponding order to ensure seamless playback.

Benefits of Using a Video Content Delivery Network for Live Streaming

A video content delivery network is always preferred over traditional methods like single-server delivery.

Intuitively, it may make sense to stream directly from the source rather than having the stream go through an extra server. However, in reality, a CDN can effectively address several limitations of single-server streaming and provide additional benefits as well. These include:

Latency and Buffering Reduction

Using a video streaming CDN for your live stream can significantly improve the playback experience for your users. Although any kind of live stream will have some delay, leveraging a CDN for your live stream helps make the experience as close as possible to real-time.

When using a single-server setup, the quality of the playback experience depends on the user's distance to the server. This introduces latency and can make the stream buffer constantly as it can't catch up fast enough to the player's current position.

But, when you use a CDN, you reduce the distance that a stream takes to reach the user. The vast network of geographical servers ensures that there's always a server that's relatively closer to the user's location.

Even with an added server in the network, the round-trip time (RTT) of origin server to edge server to user is usually much lower than origin server to user. This means a significant reduction in latency, faster content delivery, and reduced buffering.

Resource Optimization

Content delivery networks don't just balance the load of your network. They help distribute the processing burden by giving streaming tasks to edge servers. This helps alleviate strain on the origin server's hardware to better utilize resources in an efficient and cost-effective way.

Distance isn't the only factor when it comes to a live stream's performance. Having multiple users trying to access the same content from a server can really put it under stress.

When you stream directly from your origin server, it handles the entire workload of encoding, packaging, and delivering the video stream. This can be resource-intensive, especially during peak viewership times.

With too much stress on a single server, your live stream could end up buffering, dropping in quality, or failing entirely. That's not the kind of experience you would ever want to give to your viewers, especially when 67% of viewers think quality is the most important factor when watching live streams.

Distributing the load also helps your origin server focus on its core tasks like content management and security, while the edge servers handle the real-time delivery aspects. This frees up valuable resources on your origin server, allowing it to function more efficiently.

Enhanced Security

While CDNs are primarily known for improving performance, using them can also be seen as extending a wider security net around your live stream.

While the core function of a CDN focuses on performance optimization, its geographically distributed network offers enhanced security as a valuable secondary benefit.

Unlike a single origin server, a CDN's network of edge servers acts as a distributed security layer. This makes it more difficult for malicious actors to target your stream with attacks.

For instance, DDoS attempts would need to overwhelm numerous edge servers spread across the globe rather than a single point of origin.

High Availability

Another major benefit of using CDN video streaming is that you have multiple servers in the network to act as failback should something go wrong. Having these other servers on standby ensures there's always a server available for backup.

Relying on a single streaming server creates a single point of failure. This means that if your origin server experiences an outage due to hardware malfunction, software error, or even a scheduled maintenance window, your entire live stream goes down.

Downtime, even for brief periods, can have significant consequences, leading to lost revenue, frustrated users, and reputational damage.

Thankfully, this problem is eliminated with CDNs. Even if a single edge server encounters an issue, the CDN automatically routes viewers to the next closest healthy server. This redundancy ensures minimal disruption and near-continuous uptime for your live stream, even if there are unforeseen technical hiccups.

Flexible Scalability

The diverging nature of CDNs makes it really easy for your organization to scale its streaming infrastructure depending on the needs. If your viewers suddenly peak, you won't need to suffer the consequences of your resources being bottlenecked to keep up.

Without a CDN, you may find yourself constantly having to upgrade your streaming infrastructure every time there's an increase in your viewership. Additionally, you may have to spend time, effort, and resources to maintain and service that infrastructure.

A video content delivery network gives you a more scalable option for live streaming. CDNs can automatically allocate additional resources from their vast network of edge servers during peak times. Businesses don't have to focus on the technical complexities, which allows them to focus on delivering a smooth and reliable streaming experience.
