A content delivery network (CDN) is a collection of geographically distributed servers designed to accelerate web content delivery by bringing it closer to users.
There are currently 93,835,953 websites that use or have used a CDN, including 39,762,270 live websites and 54,073,683 sites that previously used a CDN.
What is CDN?
CDNs utilize a process called “caching,” which temporarily stores copies of files in data centers worldwide, enabling you to access internet content from a nearby server.
A content delivery network (CDN) is essential for providers and website owners because it simplifies the transfer of content such as images, videos, and website files to multiple servers distributed globally. This improves the user experience, particularly for users far from the origin server, speeds up web page loading times, and reduces the strain on the main server.
How does a CDN work?
Accessing cached content on a CDN network edge is typically transparent to the user. CDN management software dynamically determines the nearest server to the user, processes the request, and delivers content accordingly. CDN edge servers communicate with the origin server to provide both cached and new content to the user.
Edge servers minimize the distance that content travels and the number of hops data packets take. During an internet attack or outage, cached content hosted on a CDN server remains accessible to users near edge locations until the CDN server’s time-to-live expires.
For example, if a website server becomes unavailable, visitors can still access the website if it was correctly cached on various geographically dispersed servers.
What are the uses of a CDN?
CDNs primarily serve to distribute content securely and efficiently through a network of servers. They enhance content security, performance, and availability. Additionally, CDNs are used for collecting user analytics and monitoring network traffic. They support a variety of content types, including websites, mobile applications, streaming media, and downloadable objects. CDNs also handle traffic from social media platforms and search engines.
Here are a few examples of how CDNs are utilized:
- An e-commerce company employs a CDN to ensure smooth content delivery during peak traffic periods, such as holidays or sales events.
- A bank utilizes a CDN to securely transmit sensitive customer data.
- A mobile app developer uses a CDN to improve loading speeds and responsiveness, enhancing the overall user experience for mobile users.
