CDN is content delivery network, a distributed network that serves website assets from locations closer to users.
Example of CDN
Visitors in different regions request the same product image. A CDN can serve cached copies through its distributed network, while the site’s origin remains responsible for uncached or dynamic responses according to the configuration.
Why CDN matters
It matters because development decisions affect speed, security, scalability, tracking, SEO, and maintenance. A site that looks good but is fragile or hard to update can quietly hold back every marketing channel.
