What is a CDN (Content Delivery Network)?
A content delivery network (CDN) is a set of geographically distributed servers that work in tandem to provide fast, efficient and secure delivery of internet content. A CDN enables the rapid transfer of assets needed for loading internet content, such as videos, images, stylesheets, javascript files, and HTML pages.
Today, the majority of internet traffic is delivered through CDNs, including traffic from major internet entities (media companies and e-commerce vendors) such as Amazon, Facebook, and Netflix. A CDN that is properly configured may also protect websites from the wrath of cybersecurity threats, including Distributed Denial of Service (DDoS) attacks.
While a CDN does not host content, it utilizes caching to prevent service interruptions and improve website security.
Do You Need a CDN Provider?
The benefits of using a CDN vary depending on the needs and size of an internet entity. A CDN provider may enable internet entities to deliver content to their end users while providing a reliable, secure, and fast online experience. The benefits of a CDN provider include:
- Improved website load times
- Reduced bandwidth costs
- Increased content availability
- Improved website security
We have made the procedure of choosing a CDN provider much easier for you. Here are the top five content delivery network providers.
