# ByteArk Fleet User Guide
# Basic Concepts
A Web CDN functions by routing user requests through distributed CDN nodes instead of directing traffic straight to your origin server. These CDN nodes act as intermediaries, receiving user requests and proxying them to your origin server when necessary. In many cases, CDN nodes can serve cached content directly to users without having to query the origin server, significantly reducing origin load and improving response times.
The CDN can be utilized in two primary modes:
- Direct CDN hostname integration - Optimal for API endpoints and static asset delivery (images, scripts, etc.)
- Custom domain configuration - Required when domain-specific routing is needed, involving DNS configuration to route traffic through the CDN layer
