Why CDN for Blogs
Without a CDN, your blog is served from one server location. A reader in Tokyo loading a page from a US server waits 200-400ms just for the network round trip. A CDN caches your pages on 200+ edge servers globally — reducing load times to under 100ms worldwide.
Options
- Cloudflare (free tier) — Easiest setup. DNS proxy. Automatic caching. Free SSL.
- Vercel/Netlify — Built into the platform if you deploy there. Zero config.
- CloudFront — AWS CDN. More complex setup but highly configurable.
- Bunny.net — Simple, affordable. Good for media-heavy sites.
Cache Strategy
Static blog pages should be cached aggressively: Cache-Control: public, s-maxage=86400, stale-while-revalidate=3600. Use webhook-triggered cache purge when content updates.
