CDN is the basis for a big part of how the Internet works today. When you’re using video services,you’re guaranteed to get in contact with it, but more and more often for even regular web pages.
What is a CDN?
CDN stands for Content Distribution Network – a distribution network for content in Swedish. A network of nodes in different geographical locations helps to distribute content.
Think about the great video services that most people use today. How would it be if there was only one server behind, that would suddenly deliver a new section to lots of viewers all over the world? The server would of course crash of the pressure, and no one would see anything.
Luckily, it doesn’t work like that – instead the user is send it different servers all around the world, where the same content is cached on an intermediate storage. If a server becomes overloaded, new viewers are sent to another!
How can I benefit from this?
If you’re using video services, for example Rackfish Streamio or Live services, then you already have CDN without you having to do anything.
If you want to get an extra go on your website (or for that matter want CDN for your own video service) then it might be a good idea to invest in a CDN.
5 wins with CDN
- Better for the visitors – the content comes closer and the page is loaded from several servers instead of just the web server
- The server can do more – because it doesn’t have to handle the load, that instead is handled by the CDN
- Sudden traffic peaks do not affect the same way, as the server can do more and more parts are working together.
- More visitors – Since faster sites are rewarded in the search results, CDN is recommended by, among others, Google. And the visitors will be happier!
- More sales. There are plenty of studies, that show the connection between faster site and more sales.
