DNS là hệ thống ánh xạ domain name đến server hoặc service phía sau. Hệ thống ánh xạ tên miền tới server hoặc dịch vụ phía sau. Trên Cloudflare, bạn quản lý bản ghi DNS và có thể bật proxy (đám mây cam) để traffic đi qua edge. DNS maps a domain name to the server or service behind it. Maps domain names to servers or services. On Cloudflare you manage DNS records and can enable the proxied (orange cloud) mode so traffic flows through the edge. DNS maps a domain name to the server or service behind it. Maps domain names to servers or services. On Cloudflare you manage DNS records and can enable the proxied (orange cloud) mode so traffic flows through the edge.

Edge là lớp xử lý của Cloudflare gần user. Security checks, caching, routing và compute có thể diễn ra tại đây. Lớp xử lý gần người dùng (hàng trăm thành phố). Kiểm tra bảo mật, cache, Workers và routing có thể chạy tại đây thay vì chỉ ở data center của bạn. The edge is where Cloudflare processes traffic close to users. Security checks, caching, routing, and compute can happen here. Processing close to users (hundreds of cities). Security checks, cache, Workers, and routing can run here instead of only in your data center. The edge is where Cloudflare processes traffic close to users.

Khi một DNS record được proxy qua Cloudflare, traffic sẽ đi qua Cloudflare trước khi đến origin để áp dụng security/performance/routing/visibility. Khi bản ghi được proxy, mọi request HTTP/S đi qua Cloudflare trước origin — cho phép WAF, cache, routing và analytics mà không đổi IP origin công khai. When a DNS record is proxied through Cloudflare, traffic goes through Cloudflare before the origin so Cloudflare can apply security, performance, routing, and visibility. When a record is proxied, HTTP/S requests hit Cloudflare before the origin — enabling WAF, cache, routing, and analytics without exposing the origin IP.
