What is the main purpose of a content delivery network (CDN)?

A content delivery network (CDN) primarily focuses on enhancing the performance and speed of website content delivery to users. By strategically distributing content across multiple geographically dispersed servers, a CDN reduces latency and improves page load times for end users. When a user accesses a website, the CDN serves content from the nearest server, which minimizes the round-trip time for data transmission, making websites not only faster but also more responsive to user interactions.

This ability to deliver content quickly leads to an improved user experience, which is critical for engagement and retention. In addition, a CDN can handle traffic surges efficiently, ensuring that a website remains operational even during high-demand periods. Therefore, the main purpose of a CDN revolves around optimizing the speed and performance of websites.
