Yes, we build web applications…and there are plenty of them around. Some are or will be presented here on MyTestBox.com. Now, if we hit the jackpot and our application becomes very popular, traffic goes up, and our servers are brought down by the hordes of people coming to our website. What do we do then?

Of course, I am not talking here about the kind of traffic Digg, Yahoo Buzz or other social media sites can bring to a website, which is temporary overnight traffic, or a website which uses cloud computing like Amazon EC2 service, MediaTemple Grid Service or Mosso Cloud Hosting service.

I am talking about traffic that consistently increases over time as the service achieves success. Google.com, Yahoo.com, Myspace.com, Facebook.com, Plentyoffish.com, Linkedin.com, Youtube.com and others are examples of services which have constant high traffic.

Knowing that users want speed from their applications, these services will always use a Content Delivery Network (CDN) to deliver that speed.

What is a Content Delivery Network?

A Content Delivery Network (CDN) is a collection of web servers distributed across multiple locations to deliver content more efficiently to users. The server selected for delivering content to a specific user is typically based on a measure of network proximity. For example, the server with the fewest network hops or the server with the quickest response time is chosen. This will help scaling a web application by taking a part of the load from the service servers.

You can find more about CDNs here: http://en.wikipedia.org/wiki/Content_Delivery_Network

Some large services use their own Content Delivery Networks, but sometimes it is more effective to use a third-party CDN provider. Plentyoffish.com, for example, uses a third-party CDN (it can’t afford to have its own CDN). Both Myspace.com and Friendster.com also use a CDN.

You can see in the image below how Peer1 Networks from Canada has its own CDN setup. This kind of setup is applicable to most of the Content Delivery Networks infrastructure.

There’s an inflation of services which offer content delivery solutions and venture capitalists still pump money into more CDN solutions.
