CloudFront vs Cloudflare

CDN choice.

Overview

CloudFront and Cloudflare are the two dominant CDN choices and they optimise for different things. CloudFront is the AWS-native option with deep S3, ALB, and Lambda@Edge integration; Cloudflare leads on standalone features (Workers, R2, Bot Management, best-in-class DDoS). The right answer depends on where the origin lives and which edge features the team actually plans to use, not on which logo ranks higher in a Gartner quadrant.

• CloudFront strengths. Native AWS integration, tight IAM, OAC for S3, Lambda@Edge for request-time logic. Best fit for AWS-heavy origins.
• Cloudflare strengths. Workers, R2 (zero egress), Pages, Bot Management. Best fit when edge features drive the choice.
• Pricing model. CloudFront is usage-based per byte and request; Cloudflare is per-domain plans plus add-ons. Variable traffic favours CloudFront, predictable budgets favour Cloudflare.
• Edge presence plus DDoS. Both run hundreds of POPs and deliver sub-50ms latency globally; Cloudflare's DDoS absorption is the industry reference, CloudFront's relies on AWS Shield.

The approach

Pick the CDN by where the origin lives and which edge features actually matter. Document the rationale per property so future migrations have a paper trail rather than a vibes call.

• CloudFront for AWS-native origins. S3, ALB, API Gateway, Lambda. Same IAM, same VPC, same console.
• Cloudflare for Workers and R2. Edge compute plus S3-compatible storage with no egress fees. Modern app workloads with a global footprint.
• Cloudflare for DDoS-heavy threat profiles. Bot management, WAF, and DDoS absorption are the headline features. Right when those drive the spec.
• Document the choice plus pricing model. Per-property rationale and pricing model captured. Quarterly review catches drift between projected and actual cost.

Why this compounds

The right CDN makes the next ten edge decisions easier. Performance wins are user-visible, cost discipline shows up in the cloud bill, and the team builds edge expertise that transfers across properties as the business adds them.

• Better performance. CDN matched to origin and traffic shape. Users see sub-50ms responses.
• Better cost. Pricing model matched to traffic profile. Bill stays inside the budget envelope.
• Operational fit. CDN matches existing tooling and IAM. Velocity stays high.
• Year-one investment, year-two habit. First selection sets the patterns; by year two, every new property gets the right CDN on day one.
