Why edge alongside a CDN
- CDN: static assets + cacheable HTML at the network edge.
- Edge: short-lived logic (cookies, geo headers, tiny personalization) close to users.
- Do not move your whole data domain to the edge—keep the source of truth at the origin/DB.
Caching patterns
- Cache-Control + stale-while-revalidate for marketing pages.
- ISR / tag revalidation in Next.js for editorial content.
- Split public HTML from authenticated dashboards (avoid aggressive caching).
Security basics
- Secrets belong on the server with rotation—never “hidden” in client bundles.
- Rate limits on public endpoints + WAF where it pays off.
Common mistakes
- CDN: static assets + cacheable HTML at the network edge.
- Edge: short-lived logic (cookies, geo headers, tiny personalization) close to users.
FAQ
Does every site need edge?
No. Edge helps for low-latency and small logic; heavy reporting and CRUD stay at the origin.
