Hello,

If we are Using 2 CDN networks for one server.how it will work?

Our website is a Audio Streaming website...We are planning to mirror 2 CDN servers to cache ht content from Our Server.

Is this will increase the streaming performance?


Also which is the best Audio format to stream online for maximum performance..we are using Mp3 as the default file..but if any better formats are there to stream..then we can use that...
we are streaming online and using iphone app...

two CDN networks? like LimeLight / SimpleCDN / CloudFront ?
Whatever for ?

DO you mean 2 streaming servers? this makes more sense.....

You will need a load balancing solution between both servers.
For starters, a simple round robin DNS may suffice.

This will improve the overall performance and potentially the user experience, as the network load and server load are divided between two nodes.

imho, you only need 1 CDN.

A CDN is a Content Delivery Network, meaning they copy and distribute your cached content among their entire network of nodes. When a visitor to your web site watches the content, not only is the load balanced between different nodes, but the content is supposedly served from the nearest geo-location.
Using 2 CDN for the same purpose will only cost you more...

I can imagine some really far-fetched scenarios where you end up using 2 CDN. For example, geographical specialization. One CDN covers North America really well, and the other cover South-East Asia really well.

So, I suggest that you save a few bucks and chose one CDN. The selection criteria are cost, ease of management, node deployment near your customers, ease of integration, and maybe advanced features like content authorization.

Hello,

     Thanks for you reply and solution...i`ll accept this as a multiple solution..could you answer me for one more question...If we are using 2 CDN according to geographical specialization...Using Dyn.com cdn manger or any other DNs providing and management services...in this case...can we get more performance or is that waste of money..
Let me giv you an example...Lime light network have server in Newyork east and washington East part
other Simple CDN network have Servers in New york west and washington west...
in this case...if we use these wto CDN networks...is this will give high performance  for Streaming or nay content delivery?
if one user is accessing form new york east...then he`ll get the content from Newyork east server (limelight) or does it will take form west(simple CDN) and East(lime light)

You correctly understand that ff you use 2 CDN, you need yet another solution to balance traffic between them.

If you get to the point that you get so much traffic that you need to differentiate betweem NY west and washington west, and you are willing to pay for it and for the management hassle, then switch to Akamai.

Until then use the CDN that is better suited for you

Cheers,
