The internet is growing in popularity, and its reach has long been unparalleled. Its function as a medium for disseminating information around the globe has gained increasing importance in recent years as companies use it to reach out to their customers in new and innovative ways, such as through the use of social media, whilst organisations such as Wikileaks controversially aim to make government, and their secrets, more transparent. The internet is therefore at the centre of many people’s entire lives, let alone just their digital lives. This has been made possible thanks to the creation of rich online services, from software as a service (SaaS) packages to interactive social media portals and online shops, everything can be done online. To facilitate the massive increase in data that these services require, the CDN network was created. Content delivery networks help to serve data around the globe and have been created to help improve the performance of many different types of website. With a diverse array of servers located at several different points of presence around the world, CDNs store multiple copies of an entire website’s data collection on all these servers. The advantage here is twofold. Firstly, when end users visit a website and click on a link, they are sent to the data location that is closest to them. For example, if they are based in Australia, they will be sent to an Asia Pacific server to download the data. This is the best arrangement of data in terms of performance, as it reduces the number of hops an end user is subject to when accessing data, and therefore reduces data latency and increases download speeds. The second key advantage of storing data like this is that if one server fails or experiences prohibitive levels of traffic, users can be rerouted to the next closest server, with servers working as live backups. Data on the server is constantly updated as website owners push new data to their origin server, so no one ever needs to worry about out of date information. The CDN network is truly here to stay. It has provided a great deal of technological innovation that has ensured internet performance will increase well into the future and enable the emerging economies of Asia and Latin America to take full advantage of the internet, whilst also securing the developed world’s insatiable appetite for everything web based.
