Understanding Content Delivery Networks (CDNs)
What is a CDN?
A Content Delivery Network (CDN) is a system of geographically distributed servers that work together to provide fast and reliable delivery of digital content to end-users. It functions by caching and delivering content from the server closest to the user’s location, thereby reducing latency and improving website performance. In essence, a CDN is a crucial component of modern web infrastructure that enhances the user experience by providing fast and efficient content delivery.
How CDNs work
Content Delivery Networks (CDNs) are an essential part of modern-day web infrastructure. They help to reduce latency and improve the delivery of web content to users by caching and delivering content from the edge server closest to the user.
In this section, we will take a closer look at how CDNs work:
Directing User Requests to the Nearest Edge Server
When a user requests content from a website, the request is initially sent to the origin server, which is typically located in a data center. However, this can result in longer response times and increased latency, especially for users located far away from the origin server.
CDNs address this issue by directing user requests to the nearest edge server. These edge servers are distributed across multiple locations around the world, which means that users can access the content they need from a server that is geographically closer to them.
Retrieving and Delivering Content to the User
Once the user request has been directed to the nearest edge server, the edge server retrieves the requested content from the origin server. The content is then cached on the edge server, which means that it can be delivered to other users who request the same content in the future.
When a user requests content from the CDN, the edge server delivers the cached content directly to the user. This reduces the time it takes to deliver the content and improves the overall user experience.
It’s worth noting that not all content is cached on the edge server. For example, content that is frequently updated or that is unique to each user may not be cached. In these cases, the edge server will retrieve the content from the origin server each time it is requested.
Overall, CDNs play a critical role in improving the delivery of web content. By caching and delivering content from the edge server closest to the user, CDNs help to reduce latency and improve the user experience.
