Akamai vs AWS Cloudfront CDN Services for Live Video Streaming
Table of Contents
By 2022, online video will comprise over 82% of all consumer internet traffic. And live video streaming, in particular, is exploding in popularity. Cisco predicts that live video will grow fifteen-fold by 2020, making up 17% of total video traffic. Today, CDNs exist to solve the problem of content delivery: moving data around the planet to viewer devices worldwide. And increasingly, that data is made of video. In this article, we’ll focus on CDN services for live video streaming for professionals.
Specifically, we’ll compare the largest, oldest, and most robust CDN, Akamai CDN with Amazon’s CDN offering: AWS CloudFront. Each is a robust CDN. However, we will show in this article why AWS is not the best choice for delivering live video.
The Top CDN Pick: Akamai
We’ll begin with Akamai. Akamai is the originator of the Content Delivery Network and is based in Massachusetts. Since creating the entire CDN concept, Akamai remains the market leader today.
Each server runs the Akamai Intelligent Platform. This software package uses algorithms to analyze traffic and congestion, and intelligently process and route data requests. All of this allows the Akamai CDN to deliver data where it needs to go, fast.
Akamai serves as much as 30% of all internet traffic at any given time, which amounts to more than 3 trillion interactions. Major customers include Apple, BBC, the Olympics, Microsoft, ESPN, Hulu, Adobe, IBM, Sony, and Yahoo. Akamai is also the leader in live content, delivering massive quantities of live streaming video each day.
Runner-Up CDN: AWS CloudFront
Seattle-based Amazon provides a wide range of cloud services via its AWS (Amazon Web Services) platform. In fact, ASW is the largest public cloud in the world. It offers a range of hosting, storage, and other services, as well as a CDN service. In this post, we’re talking about AWS CloudFront CDN. However, CloudFront is not AWS’s main offering. It is simply one service among many others for Amazon.
CloudFront has been growing very rapidly over recent years. Just a few years ago, it was a small CDN mostly suited for the SMB market. Today, larger businesses increasingly use CloudFront as well, primarily for on-demand video. Many of those customers have grown.
CloudFront customers include ZenDesk, NASA, PBS, and IMDb.
Why AWS is Not the Best CDN Service for Live Video Streaming
There are several different reasons why Akamai is better than AWS / CloudFront for B2B live streaming solutions. Overall, it comes down to scale, performance, reliability, and pricing. In each of these four key categories, Akamai outperforms CloudFront according to our analysis. Let’s look at each of these categories in detail below.
One of the most important metrics for a live streaming CDN is simply the size of the network. The larger the network you have, the more endpoints to which you can direct users. This means that you are closer to any given internet user, which decreases congestion and dramatically improves the user experience. Additionally, a large network allows you to have servers in many different geographic zones, allowing you to be near all your users.

This means that you are closer to any given internet user, which decreases congestion and dramatically improves the user experience. Additionally, a large network allows you to have servers in many different geographic zones, including China, SE Asia, the Middle East, Africa, Europe, South America, Australia, and North America. Refreshed every six months, these servers are connected to more than 1,700 networks, allowing you to be near all your users. As one review notes, “it’s everywhere.”
CloudFront’s network is much smaller, with only 123 PoPs in 41 countries. And multiple third-party reviews from software programmers and testers indicate that the CDN is “too complicated and hard to automate.”
Frankly, CDN performance is hard to measure. It’s a little like the gas mileage of a car. It depends on so many factors—weight, weather, road surfaces, hills, speed, number of stops—that it’s only a ballpark measure.
Similarly, CDN speed cannot be simply measured using one definitive number. Performance depends on who is testing, where they are located, network congestion at that time, the user’s home internet speed, other applications that are running, concurrent cyber attacks, and so on.
However, we can see from existing comparisons that Akamai seems to have a definite lead over CloudFront when it comes to performance. In one analysis of CDN throughput (a good metric for looking at live video streaming performance), Akamai was roughly 14% faster than CloudFront. International tests also tend to show a 15-20% speed advantage for Akamai as a result of its larger global distribution. This is particularly important for live streaming as it leads to fewer viewing problems such as buffering issues.
There are two main components when it comes to reliability: availability and security. As far as availability, Akamai’s network sits at 99.77% according to CDN Finder. Cloudfront is rated for 99.74% in terms of availability.
However, Amazon has lagged behind most CDNs when it comes to security. Akamai, on the other hand, has been a market leader in the beginning. Akamai was the first CDN to offer DDoS and WAF protection. Their “Kona Site Defender” service protects against a wide range of threats. Typically, Akamai security offers are managed by experienced in-house professionals, requiring little setup and interaction from users.
Amazon’s CloudFront pricing is relatively aggressive. They have a simple, pay-as-you-go structure although there are a lot of extra charges, for things like ingesting and signaling, that need to be taken into consideration.
Akamai has a more complex pricing system, which is based on negotiated contracts. It’s not transparent. Pricing will depend on bandwidth, geographic region, types of traffic, contract length, and so on. Check out this live streaming CDN pricing comparison for more.
However, there’s a trick. By using a video streaming solution such as Dacast, you can gain access to the Akamai network with low, predictable monthly pricing. Dacast provides a range of tools for uploading videos and live video streaming. All content is delivered via Akamai. This gives you all the benefits of the Akamai platform without the difficulties of custom contract negotiation.
Akamai is the Best CDN for Live Video Streaming
The WordPress Code blog calls Akamai the “absolute leader in the CDN market.” It also notes that Akamai is the best platform for adaptive media delivery and advanced security features.
The CDN community agrees, showing Akamai with a wide range of advantages over CloudFront.
When you look at the top 1,000 most-visited websites in the world, Akamai serves more than twice as many of these as CloudFront. That’s because Akamai tends to win out over CloudFront in terms of performance, security, and optimization features for those markets.
Akamai is the market leader with over 50% market share based on annual revenue globally and has the majority of fortune 500 companies as customers, making it the clear winner.
As we mentioned, the best way to gain access to the Akamai CDN service for live video streaming is to work with an online video platform like Dacast. All Dacast live streams and VODs reach viewers via the Akamai network. This ensures maximum speed and reduces buffering and lag—no matter where your audience is located, or how big it is.
