What is Content Delivery Network?
Content Delivery Network is basically what the name tells you; a network for delivering content. CDN transfer copies of data to several edge nodes in a global network of data centers. So when a user wants to download a file they saved on a server, they get access to the nearest copy of the file based on where on earth the user is located. We use Push Technology for data transfer within our CDN. When data is uploaded to the server, the data is immediately pushed out from the source as copies to our edge nodes.
This means that customers get immediate response when they need to download the data no matter where they are located.
Benefits of CDN
Websites with a lot of content perform a lot better when using CDN. Since CDN enable traffic at a much higher speed, time consuming page loading is no longer an issue.
CDN leverages the positive effects of a worldwide distributed network of data centers, without the costs of infrastructure investments.
CDN augments the security regarding your customers' websites. Distributing website traffic on a CDN can make even a moderate sized DDOS attack ineffective since data is distributed on several nodes instead of one. By caching your site on a CDN you are also able to handle the “Slashdot Effect” with overloading and crashed servers and instead enjoy the benefits of so many end users visiting your site.
What We Do Different
We use different providers of networks to maintain independence. Being vendor independent is an important part of our culture. Our religion is that we do not take part in any religion, proprietary or open source. We use the parts we like without putting any beliefs in it other than that it’s the best for us and our customers.
We do not charge for traffic within the CDN network like many other providers do, only when you download a file from the network and transfer it outside the network. When someone is downloading outside the network it's easier to control the traffic (and your expanses) with passwords and other restrictions. CDN is often bespoken of being an expensive service, and of course when you get charged every time someone is downloading or sharing files within your network and get billed for it, the numbers tend to fly.
