Explain the difference between using a CDN and a CNAME record for a WebSocket endpoint.

A CDN (Content Delivery Network) distributes your WebSocket content across multiple servers globally, reducing latency for users. A CNAME record maps a domain name to another domain name, allowing DNS resolution to point to the CDN's servers. You'd typically use a CDN *in conjunction with* a CNAME record to deliver the WebSocket content efficiently.
