With the advent of technological changes, internet and consumption of internet’s data is increasing more rapidly. Internet have bring the people more closer than ever. With focusing on the superior delivery of the contents by creating rich experiences among users, many companies around the world are implementing CDN-Content Delivery Networks. In Nepal also, many national and international service provider are providing reliable and paramount CDN services with proliferating their business.
Before going on the main topic, we need to know the basic fundamentals of CDN, working principle and why it have been favored more than installing servers.
CDN stands for Content Delivery Network. It is the decentralized servers networked together to provide the faster service. Generally, these are the cache servers which stores the frequently accessed contents into them and upon request, they simply deliver. They tie up with the main servers and share the contents. Facebook, Google,Microsoft and many more companies which are content based tech industry are now the major users of CDN services.
Have you ever notice, why Google and YouTube is fast in Nepal but why not TikTok?
The simple answer is they uses cache servers to store the contents. They have installed the cache servers in Ncell and NTC premise along with other ISP’s to deliver the contents more faster. So their contents delivery rate is higher leading to faster while other services like Vimeo video and TikTok are slow.
How CDN works?
Lets directly jump on an example of Facebook. Facebook has its main servers in USA. However its traffic comes from all the countries. In order to access to my facebook contents, I need to get connected to the servers located in USA. If I am in Nepal and the data is in USA, the data from servers need to travel a long distance to Nepal. Ultimately, it would take a lot more time to get access to Facebook. Now after adding cache servers in Nepal, the contents will be available from Nepal and the time to fetch it would be very less. Ultimately, making an effective faster services.
The CDN servers generally connect with Internet Exchange Group to provide the CDN services. Details: Insight depth of Nepal Internet Exchange(NPIX)

They have used the CDN to share the contents. When any contents primarily news are updated on their sites, at first the main hosting server stores the contents in their server. Now the same contents are shared to the multiple CDN servers located to various places across the world. So wherever the main hosting server is located, the CDN helps to deliver the contents as if the hosting server is within the country. This is reason why, onlinekhabar shows the content as soon as we hit the enter key.
The below figure depicts clearly on how the shared CDN networks works effectively.
Why companies prefer CDN rather than the main hosting server?
The large social media companies like Facebook, Twitter and Google have been implementing CDN networks all over the world but why not hosting server? The reason is, in-order to create a new server, it would cost much more money. So instead, they tie up with the local telecom and ISP vendor and put their cache servers in their existing facility. This type of partnership is almost all around the world to provide the service but by cutting the expenses.
