Latest List Of Vendors In The Content Delivery Ecosystem

It’s been eight months since I last updated my list of vendors in the CDN ecosystem and since then, some changes have taken place. Below is my most up to date list, with many new companies like Aryaka, Comcast, Hibernia Networks, MileWEB, MaxCDN and others having been added. (You can easily find this list at anytime by going to

The term CDN means many things to different people and today, is an umbrella term that covers a lot of different types of content delivery services. Video streaming, software downloads, web and mobile content acceleration, licensed/managed CDN, transparent caching, FEO, and services to measure CDN performance, load balancing and analytics and cloud intelligence. It’s a complex ecosystem with a lot of vendors both large and small. You also have some CDNs that cross over into other industries like security and WAN optimization, two segments that for the most part, are not included in my list.

This list only includes commercial services in the market and does not include companies who have their own CDNs, like Netflix, Google, Microsoft, Apple, Twitch, Facebook etc. If you think your company should be added to any of these lists, see the bottom of the post for instructions.

Vendors In The CDN Ecosystem

We hear a lot about telcos and carriers in the CDN market, but the vast majority of them have built out CDNs for their own internal use and are not selling it as a commercial CDN service. So it’s not accurate to say that they all compete with traditional service based CDNs. There are a few exceptions like Level 3, Verizon (EdgeCast), Comcast and Tata who offer commercial CDN services and compete against other commercial CDNs, but most telco and carrier based commercial CDN services are based off of reselling a traditional CDN, for example AT&T reselling Akamai. This telco/carrier list is far from being complete and many more still need to be added.

Telco/Carrier Based CDN Deployments

In addition to the current crop of vendors in the market, I think it’s important to remember how the CDN industry got to where it is today. Many CDNs raised tons of money but didn’t have a business model, some only focused on selling at the lowest price and many had technology that simply didn’t work. Lots on CDNs went under, some within a short time of launching. The CDN market has been through a lot of hard times over the past 19 years and here’s a running list of those who got acquired or went under.

CDN Related Vendor Acquisitions/Closures

Each time I make a list of vendors, for any solution or service in the market, I always get emails from companies asking why they are not on the list. If you think you should be added to the list, please add it to the comments section but note that I am not listing regional hosting providers or companies who get most of their sales from $100 a month customers. Also, just because you are not on this list doesn’t mean you don’t have a valid solution in the market, but the companies listed are the ones I get asked about most often, get mentioned in the media, are included in major RFPs and promote and market their services to medium and large customers.

  • Hi!

    We are one of the companies that would very much like to be on your list. I work for Arkena (, and we are the result of a merger of the 4 companies; Cognacq-Jay Image, PSN, Qbrick and SmartJog, now a part of the TDF Group.

    Let me know if you need more info, and I hope you can fit us in!

  • Hi Dan, could you please consider adding ApplianSys ( to the list? Our web cache, CACHEBOX, supports caching files delivered over CDNs.

  • Hi, would you consider adding KeyCDN ( to your list? We offer 20+ global pops with free origin shield protection and free secure token. Thanks!

    Hi Dan,
    do you have any tips or best practices in reducing CDN costs?

    • Hi Ed,
      We are value added resellers of CDN solutions, and work closely with more than 15 of the vendors on these lists. And with some others that are not. Let me give you some tips:
      * Minify your CSS, Javascript and HTML
      * Use gzip for text based assets
      * Consolidate CSS and JS if possible to reduce requests overhead
      * Optimize your images and video media
      * Use intelligent routing to serve your content out of the best point, including bypassing CDN when it makes economical sense
      * Shop around and negotiate
      * Get a partner (like us) to help you find the CDN that can help you achieve these goals and get the best value for your money

    Do you have any plans for indicating whether a CDN provider supports IPv6 access to IPv4 content as Akamai and Verizon Edgecast do?

  • Alexey

    Hi, would you consider adding SkyparkCDN ( to your list?

  • Paul Martin

    Dan, this list is helpful although I imagine it’s moved on since July 2014. Are you planning to release an updated list? Also, please can you add Concurrent ( to the list of Vendors in the CDN Ecosystem. With some of the largest US, European and Japanese cable operators as customers using our Origin, Edge and Storage solutions, and with a 12-year heritage in the VOD industry, we should definitely be in the list. Thanks, Paul Martin – General Manager, Concurrent EMEA.

  • ImageEngine ( is a CDN specialized on image optimization and delivery. Should also be on the list. Thanks.

  • Jaimon Jose

    Dan, there were lots of traction in the P2P market in the last couple of years. Streamroot, peer5, swarmify etc. have come up in that space to disrupt traditional CDN market. It will be a good idea to include them and also to consider their business model and technology landscape in your reports.

  • EL

    Hi Dan, can you add to the list? It’s a new offering by an established industry player. It’s an offering that’s based on top enterprise CDNs infrastructure and tailored to startups needs (no commitment, affordable, based on pay as you go, quick and easy setup etc.)

  • Alex Phillips

    does anyone know if there is a single association that represents the majority of the CDN’s in the US?
