CDN Service

Cloud hosting technologies has introduced some serious solutions for a large scale information management projects. CDN is one of the most popular solution.

CDN stands for Content Delivery Network. The name itself explains that this solution is used for delivering lots of content. Where content is managed in huge amounts, powerful servers are needed.

The main principle of CDN is that all the data is broadcasted from the locations which are nearest to the end user. For example the user who wants to download a large file is in China. The information is stored in several datacenters in USA, UK and Singapore. With the CDN the needed data would be downloaded from the server in Singapore, not US based server.

CDN is a solution which is used for large scale websites and services, for example file sharing sites, video and quality photo galleries, media streaming websites (like Youtube) and any websites which operates the huge amounts of data. Managing lots of data requires not only the big hard drives, but also high bandwidth, powerful hardware etc. Content Delivery network works with multi-location hosting. At least 2 different servers in different locations must be used in order to start a Content network. In majority of case CDN is an international hosting solution as servers, located in different countries are used.

How CDN Works

Content Delivery Network or CDN works on the basis of cloud computing solutions. The network of servers worldwide has enough capacity to handle the biggest information flows. All the information is stored in different nodes which are in the different services. Advanced synchronization solution takes care of content duplication in all the nodes simultaneously. The data is transferred using TCP and UDP connections which are mostly used in Peer2Peer services such as Torrents or DC++. Sometimes TCP acceleration solutions are used to get the bigger capacities of the data transfer to the end user.

The advanced CDN technology is actually observing the end visitor geo location. That means once user is requesting the information, the core server calculates the nearest server physically and all the data are transferred from the nearest data center by location. Such solution allows supporting and managing huge amounts of information despite the number of simultaneous users.

Simple server has 10 Gb/s network speed. If there are lots of information requests, the server cannot provide more than this channel. Then server start working not so well and visitors may experience some troubles and delays. If there is the network of 10 different servers in several countries the load increases by 10 – 10x10Gb/s is 100 GB/s speed which is really huge. This system allows websites not to crash even if some countries have overload.

Unlimited CDN Advantages

The advantages of CDN service are unlimited. The main advantage is the guarantee of accessibility. If regular web hosting has 99% uptime guarantee, CDN can guarantee 99.9999% of uptime. It means that most probably the website will never be down because of overuse of bandwidth or DDOS attacks.

Another advantage is the backup options. In case the core server is going down, the website will always have a few cashed copies to be recovered from.

Pricing also can be one of the main advantages, because customer must pay for the actual usage per Gigabyte, not the monthly plan fee. That is used in mobile technologies and seems to be working just fine.

Crash protection just because website got popular in one country, but not in worldwide is a huge problem for VPS and shared hosting. Not for CDN as all the resources can be allocated automatically. Once one country resource maximum is reached, other locations are activated and all the data are provided from there.

Website load speed is decreased using CDN service, therefore complex code websites may get better SEO results as Google cares about the page load speed (scripts and code, not files).

The advantages can be 10 pages list, but the main ones are mentioned.
