Do I need a CDN if my users are all in one country?

Yes, but for different reasons. Even with local users, a CDN reduces server load (cached content is served without hitting your origin), improves reliability (CDN handles traffic spikes), and adds security (DDoS protection, WAF). The performance benefit is smaller with local users, but the reliability and security benefits apply universally.

Infrastructure

CDN (Content Delivery Network)

A distributed network of servers that delivers web content to users from the geographically closest server location.

CDNs reduce latency from 100-300ms to 5-20ms by serving content from servers near the user.
Cloudflare's free tier provides CDN, DDoS protection, and basic WAF, making CDN accessible to every website.
Modern CDNs add edge computing, image optimization, and security, going far beyond simple static file caching.

CDN Providers Compared

Provider	Best For	Starting Price
Cloudflare	All-in-one CDN + security + edge compute	Free (generous tier)
AWS CloudFront	AWS ecosystem, S3 integration	Pay-per-use (~$0.085/GB)
Fastly	Real-time purging, edge computing	$50/month
Akamai	Enterprise, massive scale	Custom pricing
Vercel/Netlify	JAMstack, automatic with deployment	Included in hosting

For most websites, Cloudflare free tier is the best starting point. It includes CDN, DDoS protection, SSL, and basic analytics at no cost. Upgrade to paid plans only for advanced features like custom cache rules, image optimization, or Workers (edge computing).
