Imagine playing a game online and a 100ms delay and there goes your gaming experience. This issue of delays and roadblocks can cut short anyone’s online experience and the websites are likely to lose many subscriptions. So, what can be done? The best option in order to prevent such bumps is CDN.
What IS CDN?
CDN or Content Delivery Network, a system of distributed networks or servers, is used to deliver content from the web pages to the users depending upon the location of the user, web page’s origin, and also, the content delivery server. If we were to put it simply, it is in charge of the delivery of content and is considered as the backbone of the internet.
CDN distributes the users’ requests at various data centers instead of pooling all the requests in one place. It sends the request to the data center that is nearest to the user based on his or her location.
The newer CDN also allows distribution of video content to the users and the service effectively speeds up the delivery of the content of the websites to the users. This helps in smoother traffic and effective reach.
Over the years the Content Delivery Network has witnessed many changes and the journey from the traditional legacy systems to Cloud-based services has improved it efficiently drastically. The newer content delivery network system has the ability to foresee the availability of servers and diverts the content accordingly and thereby, has a wider reach on a global platform. The CDN allows for immediate server detection, better user experience, and overall customer satisfaction.
The latest CDN system can detect instant servers and reroute them instantly, thus, they offer continuous network distribution even in case of power failures or other obstructions. Due to uninterrupted content delivery, including video delivery network, despite any issues in network and hardware, CDN has gained immense popularity, and rightly so.

How CDN Works?
When a search is made or when a user visits a particular page, the server that is closer to the website responds and brings the content to the page. CDN reduces the distance between the website and the viewers. In order to do so, the CDN stores the files in the cache version in various locations. There are various servers that are responsible for storing the cache versions and distributing the content according to the demand.
CDN simply puts the content at various places simultaneously, in reach of the servers, thereby, making the content available to the users at their convenience. This system cuts short the time taken for servers to gain permission from a particular location and saves time for the users and gives the content a global reach.
Latency is any website’s worst nightmare and CDN works to eliminate latency while delivering the content to the users by ensuring that the content is stored at various locations on a wider geographical basis.
Challenges Of CDN’S
Although CDN has proved its worth, it is not of much use to people who want to target the local audience since not all the hosting services are designed for quick delivery of the static content. More work is being conducted on this issue and experts are trying to rectify the speed issue that many hosting services face when looking into local markets.
With the advent of new technologies on a daily basis, older generations of CDN are in-adept to meet the needs and requirements of the users of today. The need for quality, performance, and availability and cost-effectiveness is crucial for a CDN to work and the present gen CDN is failing to meet the demands.
Technological advancements can and will ensure up-gradation in CDN systems and make sure that the bumps are smoothened out and the requirements met.
CDN Of The Future – Opportunities
The CDN works on two major principles – expanding the user base and having a larger and global presence. When the CDN service providers work in association with other bigwigs in the field and by the way of mergers, acquisitions, and partnership they will be able to reach out to larger users and cross geographical barriers and also improve the broadband infrastructure and improve the media efficiency.
The trend that the CDN market can see in the nearest future will be based on the scalability of the content, availability of the servers, storage, market mechanism deployment, content delivery mobility, and much more.
