A CDN origin server is a central component in a Content Delivery Network (CDN) architecture. It is the primary source of the original content that is distributed across the network. Here are the key points about a CDN origin server:
Definition and Function:
An origin server is a computer or service that stores and processes the original version of web content, such as HTML, CSS, JavaScript files, images, videos, and other data[1][2][3][4].
It listens for and responds to incoming requests from clients, delivering the requested content[6][12].
Role in a CDN:
The origin server works in conjunction with edge servers, which are distributed globally to cache and deliver content closer to end users. This setup helps reduce latency and improve load times[1][3][4][6].
When a user requests content, the edge server checks its cache. If the content is not available or is outdated, the edge server retrieves it from the origin server[2][4][7].
Performance and Load Management:
CDNs help offload traffic from the origin server by caching static content on edge servers, which reduces the load on the origin server and improves overall performance[3][4][6].
Load balancing and horizontal scaling are often used to manage the high volume of requests that origin servers handle[1][5].
Security:
CDNs enhance security by hiding the origin server's IP address, inspecting incoming traffic, and managing traffic spikes. This helps protect the origi...
