Cloudflare vs Aws Cloudfront

Overview

Cloudflare provides CDN, DDoS protection, DNS, edge computing (Workers), R2 storage, D1 database, and KV store. Its free tier is exceptionally generous. AWS CloudFront is Amazon's CDN integrated with the AWS ecosystem, distributing content from edge locations worldwide with advanced caching and routing.

Key Differences

Free Tier: Cloudflare offers unlimited bandwidth, DDoS protection, SSL, and caching for free. CloudFront gives 1TB transfer in the first year, then charges per GB. Cloudflare free tier is unmatched. Edge Computing: Cloudflare Workers run code at the edge with sub-millisecond cold starts and 100K free requests daily. Lambda@Edge is more expensive, slower to start, and harder to configure. AWS Integration: CloudFront integrates seamlessly with S3, ALB, API Gateway, and other AWS services. If your backend is on AWS, CloudFront provides the tightest integration. Setup Complexity: Cloudflare requires changing nameservers and it works. CloudFront requires configuring distributions, origins, behaviors, and cache policies through the AWS console. DDoS Protection: Cloudflare provides enterprise-grade DDoS protection for free. CloudFront has Shield Standard (free, basic) and Shield Advanced ($3K/month).

Verdict

Choose Cloudflare for its free tier, simple setup, powerful edge computing, and DDoS protection. Choose CloudFront if your infrastructure is on AWS and you need deep integration with AWS services.
