What Is Content Delivery Network And Its Benefits?

A CDN (Content Delivery Network) is a highly distributed, interconnected group of servers that work together to ensure fast Internet content delivery. Virtually all Internet users interact with CDNs daily, from connecting with friends and family on social media to shopping online, reading blog posts, conducting online research, and watching YouTube videos.

Content delivery networks are essentially transparent backbones that facilitate the efficient transfer of online assets, including stylesheets, JavaScript files, images, videos, and HTML pages. Without these networks, content origin servers may have to respond to each end-user request, resulting in unbearable traffic spikes at the origin and slow loading times.

What Are the Advantages of Using a Content Delivery Network?

Although the advantages of using these networks vary based on the size and requirements of the Internet infrastructure company that is in question, the key benefits in most instances include:

  • Reduced Website Load Times

By bridging the physical distance between origin servers and website visitors using nearby CDN servers, your visitors can enjoy faster loading speeds and feel less inclined to click away due to latency.

  • Enhanced Website Security

CDNs act as virtual high-security fences that protect websites and applications from potential cybersecurity attacks, especially DDoS floods.

  • Lower Bandwidth Costs

Website owners have to pay for bandwidth consumption costs, among other expenses, to host their websites. CDNs use optimizations such as caching to minimize the amount of data needed from an origin server, ergo reducing bandwidth consumption costs.

What Experts Love About Content Delivery Network?

What Kyle Rush, Director for Frontend Engineering and Optimization for Hilary For America, thinks is most beneficial about CDNs is caching, because it gets the desired content to the user faster and it helps to reduce load time on the original server, avoiding traffic overload. 

Edge Delivery 

The edge delivery that CDNs bring and the caching systems along with it help solve the issue of congestion and ‘slow-down.’ It’s impressive how companies can delegate content delivery to 3rd parties. 

Proxying 

Particularly proxying, along with TLS handshake is a great aspect of CDNs. We simply cannot ignore the advancement within the CDN industry which means CDN practices aren’t dictated by bandwidth economics. 

Utility-based Platform 

According to an expert, the best thing about CDNs is that he feels that CDNs have ‘grown into a utility-based platform’ that has assisted internet companies by allowing them to focus on base-level offerings instead of distance, latency, and performance.

Internet E-commerce 

CDNs services such as video delivery, internet e-commerce as well as online gaming have provided huge benefits by allowing small companies the ability to broadcast live events which weren’t previously possible. 

In conclusion, there are lots of great aspects of CDNs and the leaders of the industry seem positive about the advancements that overcome the major hurdles.
