What are the 4 components of CDN?
A Content Delivery Network (CDN) is a system of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server. There are four main components of a CDN, which are crucial for ensuring fast and secure content delivery to users. These components include:
1. Edge Servers: Edge servers are strategically located data centers around the world that cache and deliver content from the original server to the end-users. By distributing content across multiple edge servers, CDNs reduce the distance data must travel, resulting in faster load times and improved user experience.
2. Origin Server: The origin server is the primary source of the web content. This is where the files, images, and other resources that make up a website are stored. When a user requests a webpage, the CDN retrieves the content from the origin server and then caches it on the edge server closest to the user.
3. Cache: Caching is at the heart of a CDN’s functionality. When a user requests content from a website, the CDN checks its cache for a stored copy of the requested file. If the file is available, the CDN will quickly deliver it to the user. If not, the CDN fetches the content from the origin server and caches it for future use. This helps reduce the load on the origin server and ensures faster content delivery.
4. Content Delivery Protocols: CDNs use various content delivery protocols to efficiently manage and distribute content across the network. These protocols include HTTP/2, QUIC, and WebRTC, which all contribute to optimizing the connection between the user and the edge server. This results in decreased latency, faster content delivery, and an overall better user experience.
In summary, a CDN relies on edge servers, the origin server, cache, and content delivery protocols to efficiently deliver web content to users across the globe.
