Explanation
A CDN (Content Delivery Network) solution is a service that provides faster delivery of web content to the users distributed worldwide. A CDN is essentially a group of servers that are strategically placed across the globe with the purpose of accelerating the delivery of web content. A CDN can improve the user experience for a website by:
Reducing the download speeds and latency for the end users, as they can access the web content from a server that is geographically closer to them, rather than from the origin server that may be far away.
Increasing the availability and reliability of the web content, as a CDN can handle high traffic volumes and provide redundancy and failover in case of server failures or network issues.
Enhancing the security and performance of the web content, as a CDN can provide features such as caching, compression, encryption, and DDoS protection.
Some examples of popular CDN providers are Cloudflare1, Azure2, and Amazon CloudFront3.
