Advantages of Using a CDN


What is a CDN ?

A content delivery network (CDN) refers to a geographically distributed group of servers which work together to provide fast delivery of Internet content.

A CDN enables the rapid transfer of resources such as HTML pages, javascript files, stylesheets, pictures, and videos that are required for Internet content to load. As CDN services gain more and more traction, they are now used to handle the vast majority of online traffic, including that coming from famous websites like Facebook, Netflix, and Amazon.

How does a CDN work?

A CDN is fundamentally a network of servers connected in order to distribute content as rapidly, affordably, consistently, and securely as feasible. A CDN will set up servers at the junctions where various networks meet in order to increase speed and connectivity.

However, it is critical to understand that using a CDN does not eliminate the need for web hosting. This is because the cached content that the CDN stores is done at the network edge, allowing the CDN to improve the speed of your website. A faster website is always going to be critical to the success of any website, which is why many SMBs choose to use CDNs.

What Are the Primary Advantages of a CDN?

1. Improve Website Performance and Speed

By using a web of distributed CDN servers, your web content will be closer to website visitors. That means visitors will experience faster page load times and better performance. With this in place, businesses can deliver high-performance website content quickly by caching content on the CDN servers closest to end-users, this content can include HTML code, image files, dynamic content, and JavaScript.

2. Allow Audience Segmentation Based on User Analytics

User analytics such as real-time load statistics, capacity per customer, most active areas, and the popularity of different content assets form a rich source of info that can be used to understand trends and content consumption patterns. Businesses can use these insights to help their developers optimize the website further, improve the user experience and contribute to more sales and conversions.

3. Improving Website Security

A CDN needs to be able to defend against common security risks, just like many other networks that are connected to the internet. To defend themselves against risks like on-path attacks, data breaches, and attempted network crashes, CDNs use something called TLS encryption.

4. Reduce bandwidth to help with cost savings

Through caching at the network edge CDN’s can reduce the amount of data that the hosting server needs to provide. In most cases, this reduces hosting costs on businesses, freeing up valuable resources for other initiatives.

5. Decrease Server Load

Because servers are strategically placed across vast distances, no server is in danger of being overloaded. This, in turn, frees up overall capacity, allowing for more concurrent users while lowering bandwidth and delivery costs.
