What is CDN and How Does it work ?CDN stands for content delivery network. A content delivery network (CDN) is a system of assigned servers (network) which delivers pages and more Web content to a user depending on the geographic location of the user, the source of the web page and the content delivery server.
Why you should use it?of websites that have high traffic and websites which have global reach. The closer the CDN server is to the user geographically, the quicker the content will be sent to the user. CDN’s will also maintain protection from large surges in traffic.
How CDNs WorkServer closest to the website visitor respond to the request. The content delivery network takes the pages of a website to a network of servers that are spread across various geographic locations, caching the contents of the page. Once a user requests a webpage which is a portion of a content delivery network, the CDN should redirect the request from the originating site’s server to a server in the CDN which is nearest to the user and grant the cached content. CDNs generally communicate with the originating server to deliver any content that was not cached previously. The process of jumping through CDNs is pretty transparent to the user. The one way a user will know if a CDN has been accessed is if the delivered URL is changed than the URL that was requested.
The working of a CDN serverTo help you understand the working of a CDN server we’ll do it using an example, When a user visits your website, his request is automatically redirected to your central/main server. This means that each user who enters your website accesses the central server. In case there’s a certain amount of visitors at once, your server becomes overloaded and then your website will start responding very slowly. You will also notice an increased chance of server crashes. Now, this is solvable with the use of CDN hosting from a reliable web hosting provider. Read our best Tutorials;
How can you benefit from CDN?Here’s a couple of benefits when using cloud CDN hosting:
- Improved speed: When the CDN servers are located all around the world, it helps the content load faster for the user from the server located closest to him, then the website’s loading times are better and as well as server responding time.
- Better server up time: What CDN does is it reduces the load on the central server by giving it among several servers. This decreases the chances of the central server crashing, then allowing great uptime.
- Better user experience: Once the CDN server has decreased loading times and the server crashes, you will receive excellent user experience even in times where there is high volume of traffic.
- Saves money: Once the CDN distributes the load, it also saves bandwidth. Meaning it will boost your website’s performance and decrease the costs associated with tools and software that you employ to improve your website’s speed. Causing for CDN to be a sensible way to save money.
ConclusionSo to conclude, CDN management decreases the time taken by your web hosting server to process, receive, and then deliver the content. It saves bandwidth and makes user experience a lot better. Also improving the site’s ranking and accessibility of your content across the world. It’s good to note that whenever an internet attack or sudden traffic upsurge, network malfunction or junction faults, it ensures your data is secure across all servers.
