CDN indicates Content Delivery Network‘ represents to a geographically distributed group of servers which join hands to deliver fast internet content. It permits a quick transmission required for loading internet content such as JavaScript files, HTML pages, images and videos.

And in return of it, CDN’s pay network operators to host the servers in their data centers.

Is there any correlation between content delivery network and web hosting?

The CDN can’t take place of web hosting and even doesn’t host content; it just helps the cache content to enhance the website performance. Many websites that are going through a hard time to get higher performance with traditional hosting services, they can go with CDNs.

Let’s have a look at the difference between CDN and web hosting:

1.    Web hosting mainly works to host a website on a server and give access to use it over the internet. Whereas CDN works to speed up the performance of a website as well as perform expeditious delivery of content from owner to user.

2.    The great difference in both hosting services is web hosting refers to a single server and on the other note, the content delivery network represents to a worldwide network of edge servers (come from origin server) which indicate the content is distributed from multi-host surroundings.

3.    The web hosting delivers 100% content to an individual and if a user is across the world, then they have to wait a little bit for data to be transmitted from the server location. A CDN is quite fast in a content delivery service. It serves the data across the globe effectively. This means the fastest route it follows to deliver the assets to a user as quickly as possible. 

These above differences clearly define you how traditional web hosting differentiate their existence from a content delivery network. Deeply read this because it’s good if you have any confusion between traditional or CDN hosting services.

Benefits of using content delivery network:

The advantages of using CDN depend upon the internet property you want for your work but its primary benefits are as follows:

CDN and bandwidth

1.    Minimizing bandwidth costs – Consumption of high bandwidth for web hosting has expended the expense of a website. But here we have another option to turn which is CDN because it has the capability to reduce the total content server that has provided via caching and other optimizations. Therefore, the bandwidth cost has been decreased.     

2.    Enhancing website load times – For experiencing faster and far better loading time, this server is really a good choice. As visitors are more interested to click on faster loading website and if your site has a slow loading problem then you will lose your visitors. In this situation, CDN can minimize the bounce rates and improve the loading speed so that people will stay at your site for a maximum time period. In short, you can say fast loading speed means more people are inclined towards your site and spend longer time and as a result, they’ll show interest in your services.    

3.    Improving content availability and redundancy – Heavy traffic to the website may interrupt the normal functionality of your site and might user lose connection in between the work. With distributed nature, content delivery network comes forward to handle the large amounts of traffic and stand by the side of hardware failure too. 

4.    Increasing website security – Security is one essential element that is a basic demand of all websites whether you’re running a small or large business. CDN increases web security by offering DDoS mitigation and a few more optimizations.

CDN vs Web Hosting without CDN

CDN Vs Web Hosting

The above picture indicates the working pattern of CDN and web hosting without CDN. As you can see KeyCDN Edge servers are offering fastest connection to different users whereas in web hosting without CDN, origin server distributed the connection to all users as it enhances the slow loading program when more and more users connected to a single server.

How does a CDN work?

CDN is a network that linked different servers with an aim to deliver the content to users in a quick, systematic, secure and cheaper way. A single server couldn’t entertain all the users so with the goal to improve the speed and connectivity of the internet connection or you can say improve the content delivery speed, CDN will construct servers at different exchange points and between variable networks. The exchange points are primary locations where providers are connected in order to offer access to each other when high traffic is originated at various networks. With this action, the CDN cost will be reduced and improved speed or connectivity.

How CDN helps to keep the website alive (Online) all the time?

Today, where the whole world is dependent upon the internet connection, uptime is another critical situation for the websites. Hardware failure or other minor errors will badly influence the site. This will increase downtime problem and users won’t be able to access your website on the internet. Here we list out several ways to minimize the downtime.

•    If one or more CDN servers are stopped working due to hardware failure, it distributes the traffic to different servers but never let the websites down. It is a smart move to cope up with heavy traffic around the world.

•    In the event or official meetings, if entire data goes through some serious technical errors, the CDN will transfer the entire traffic to another resource (most nearby data center). It makes sure no user will fall in a downtime problem where they have to find the actual access to the website.

 If your website is realistic to deal with images then CDN is a good option to have. Image loading is a general problem every individual has to face in their work and it impacts the reputation of your business too.
