I believe the two huge areas for grow in the CDN market will be in mobile and HD delivery.
Mobile CDN
Mobile CDN Inc (www.mobilecdn.com) has an interesting offering as a end-to-edn mobile content delivery network. They focus exclusively on mobile content delivery and have whole product solutions that help meet the growing demand for mobile content. By focusing on mobile they ensure brilliant mobile experiences that accelerate small object delivery from orgin all the way to the mobile device.
HD CDN
having tested all the solutions in the maket today one company stands of when it comes to HD and this Highwinds (www.highwinds.com) They offer a hybrid P2P delivery solution that is used by the likes of CNN: they delivered 1.3 M concurrent streams for the Obama inaugurations in 2009 and the technology is for sure firetested and mature. They offer high scale and low cost for HD delivery – see NBA league pass as and example.
In summary, new offerings that focus higher up the value chain in the CDN market may be of interest to your readers as they solve specfic problems where the pure play CDN fail to deliver. For pure http you can get great pricing from Limelight and Akamai but they not ‘all things to all men’ – even though they think they can be.
Can you please let me know How I can identify whether a site is CDN enabled or not. ?
Is there any tool which can tell me the all the cdn objects with in the site. ?
Mike could you pls show me a screenshot (from Firebug) of the CNAMEs and the NS Lookup’s for any site of your choice that represents the CDN redirection in it.
I would apprecite your help if you could do this.
What is the URL you trying to look at? You would look for anything that says like video.domain.com or static.domain.com something like that. Then go out to a command prompt and type nslookup videos.domain.com.
Look up footprint.net and it belongs to Level3. Level3 is the CDN for that Image.
Finding the CDN for videos might be more difficult as many times the URL is embedded in a SWF or JS. You might need a pack sniffer software to see where the video is loading from and then resolve that URL.
I am testing it for MSN.com.
I got it some extent here. But can you please clear me what does Level3 mean?
(If in the Addresses tag if we could found 3 IP’s does it mean that it is level 3 there? and If it doesnt show 3 IP’s/(level 3) then all those objects or not in CDN.
Is that right? Iam not sure ??)
Level3 is a CDN Provider. Why are you trying to analyze MSN? Seems like a a big task. Microsoft uses a combination of their own network, components from Limelight, and caching from Akamai. It also depends which Microsoft domain you are talking about too.
If you look at the page, there are a number of HOSTS, most of which are coming from 3rd parties. Things like advertisements, and other widgets. Those providers may or may not be using CDN to deliver their content.
In this case, http://www.msn.com is an A-RECORD not a CNAME. It resolves to a single IPAddress, probably a Load Balancer of something similar.
I have a tool which will analyze a web site. Below are all the HOSTS on the MSN.COM home page, where they resolve to and who owns the IPAddresses.
What is your goal here? Just personal knowledge or are you trying to discover some piece of information?

Mike,
Can you please let me know the tool you are using? Is it a freeware or commericial? Actually Iam trynig to know the cdn data from MSN. What are all the data that is coming from a CDN and what are from the webserver directly.
The tool I’m using is something my company wrote. I can not share it with you, sorry. I think you are wasting your time trying to figure this out for Microsoft. They have built out their own CDN, they don’t a commercial one always. Figuring out which piece of content is coming from the CDN or not will be nearly impossible. Plus MSN is behind a ton of load balancers and hundreds or thousands of servers. CDN is webservers, they just cache content and deliver it closer to the end user. Mainly, it’s just Apache or IIS.
I’m just curious, what is the point of this? It seems if you want to learn more about this, you could pick a smaller target. You might as well be trying to figure out how Google Works

nice post

Is there any tool which can tell me the all the cdn objects with in the site. ?
I would use Firebug in Firefox. Look at the CNAMEs that are loading then do a NSLookup on the CNAME and see if it’s redirecting to a CDN
@Mike

What is the URL you trying to look at? You would look for anything that says like video.domain.com or static.domain.com something like that. Then go out to a command prompt and type nslookup videos.domain.com.
For example. Go to CNN.COM right click on an image, choose properties and you see the URL like this:
http://i2.cdn.turner.com/cnn/2010/WORLD/asiapcf/05/14/thailand.anti-government.protests/t1main.thaiprotest2.gi.jpg
nslookup i2.cdn.turner.com and that resolves to:
Non-authoritative answer:
Name: cdn.cnn.com.c.footprint.net
Addresses: 204.160.119.126, 8.12.218.126, 199.93.46.126
Aliases: i2.cdn.turner.com
Look up footprint.net and it belongs to Level3. Level3 is the CDN for that Image.
