Everything You need to Know about a Content Delivery Network

Content Delivery Network

If you’re looking for an exciting business, you’re just going to know about one. Content Delivery Networks, otherwise known as CDNs tend to be the most important part of an internet business strategy. A Content Delivery Network comprises of web servers that provide highly available content with fast delivery. The main job of CDN is streamlining the content for web users.Simply put, it is a CDNs job to improve user experience and provide it to the users with efficient network resource utilizations. CDNs play the role of a bridge between content providers and the audience. Different media companies and people that are in the e-commerce sector contact these CDNs operators to deliver their content to the audience.

CDNs then pay ISPs, carriers and network operators to host servers in their data centers. Let me quickly explain to you how these CDNs function.

  • CDNs are supposed to pass the data that they receive from their clients to various data centers so that it remains in reach of the audience.
  • In order to make the content available to users in the most efficient way, CDNs work by using server optimizations which is based on the type of content.

CDNs perform another job i.e. offloading the traffic that content providers serve; it helps the content providers with saving the cost. One of the major problems in content dissemination is the fact that all the content lies at one location which means that if a user is away from the server with content on it, the user experience will be less. So let’s say, that certain websites have content stored in France, users from somewhere in America are more likely to suffer from a longer page load than end users in Paris. CDNs nodes are therefore used in multiple locations on multiple backbones to avoid this problem. The results are lesser costs on bandwidth, a much better page load time and an increased availability of the content across the globe.Take a look at hostiserver.com to find out more.

When we talk about content, there are three basic types of it that you need to understand: a) Dynamic content, b) Static content, c) Streaming content.

Dynamic content is the content that is mostly generated by the web servers by using common languages such as php, ruby or java. Then there are contents that do not change a lot such as Images, JavaScript etc. This is known as static content. Then the third type is streaming content which comprises of the video or audio files normally played by web browser control.

Since all of these are different in size therefore they are going to have a different latency. Latency is how long it takes an individual byte to get transferred to an end user. Fast web content denotes a low latency. So if we are looking at optimizing the browsing experience, one of our major focuses ought to be reducing the latency factor.The main difference between a web hosting and CDN is that web hosting hosts your website on a server whereas a CDN speeds up the access of your website’s assets.
