What is CDN and How Does it Work?
Content Delivery Network (CDN) is a distributed network of servers that delivers webpages and other web content to a user based on the geographic location of the user. CDNs store cached versions of the content of a website on its network of servers that are spread across multiple locations around the world. When a user attempts to access a website, the CDN quickly delivers the content from the server closest to the user’s location. CDNs can be used to deliver any type of content, including text, images, videos, and applications. This is why CDNs are highly beneficial for websites that have a global audience. CDNs are also used to deliver static content, such as HTML, JavaScript, and CSS, faster than traditional web hosting.
Benefits of CDN
CDNs provide a number of benefits for websites, including:
- Faster loading times for website content
- Increased website performance and scalability
- Improved search engine rankings
- Reduced bandwidth usage and cost
- Enhanced security and protection from DDoS attacks
In addition to these benefits, CDNs provide a reliable and efficient way to deliver content to users around the world. This helps website owners ensure that their content is always available, regardless of the user’s geographic location.
Conclusion
CDN is an essential tool for websites with a global audience. It helps deliver content faster and more reliably to users around the world, while providing numerous other benefits. If you’re looking for a reliable way to deliver content to a global audience, a CDN is the way to go.References: https://www.keycdn.com/support/what-is-a-cdn https://www.cloudflare.com/learning/cdn/what-is-a-cdn/ https://www.akamai.com/us/en/solutions/intelligent-platform/cdn.jsp
