Cloudflare vs AWS CloudFront — CDN Comparison for DevOps Engineers (2026)

Cloudflare and AWS CloudFront are both CDNs that cache content globally and protect against DDoS. But they have different strengths, pricing models, and integration stories.

Quick Summary

Use CloudFront if:

• Your backend is fully on AWS (S3, ALB, API Gateway, EC2)
• You need tight integration with AWS WAF, Shield, Lambda@Edge
• Your team is AWS-native and wants everything in one console

Use Cloudflare if:

• You want the best DDoS protection on the market
• You're multi-cloud or your origin isn't AWS
• You want free SSL, DNS, Bot management, and more on the free/pro tier
• You want easier setup and better developer experience

Network Coverage

CloudFront: 550+ PoPs (Points of Presence) globally. Strong in North America and Europe.

Cloudflare: 300+ cities, 200+ countries. The largest network by number of locations, interconnected with most major ISPs directly (no extra hops). Generally better latency globally, especially in Asia, Africa, and South America.

For global audiences — Cloudflare usually wins on raw latency.

Pricing

CloudFront:

First 10TB/month: $0.085/GB (US/EU)
Next 40TB: $0.080/GB
Requests: $0.01 per 10,000 HTTPS requests

Pricing varies by region — Asia Pacific is more expensive. CloudFront has a free tier (1TB/month included in AWS Free Tier for first 12 months).

Cloudflare:

• Free plan: Unlimited bandwidth, unlimited requests, CDN + DDoS + SSL
• Pro ($20/month): WAF, image optimization, mobile optimization
• Business ($200/month): Custom WAF rules, 100% uptime SLA
• Enterprise: Custom pricing, dedicated support

For most use cases, Cloudflare is significantly cheaper. The Free tier genuinely covers most small and medium sites.

DDoS Protection

CloudFront + AWS Shield Standard: Basic DDoS protection, free. Shield Advanced ($3,000/month) adds 24/7 DRT team access and cost protection.

Cloudflare: Industry-leading DDoS mitigation. Cloudflare absorbs attacks measured in terabits/second. Their network is built for DDoS at scale — they absorb some of the largest attacks ever recorded. Available on all plans including Free.

Winner: Cloudflare — especially for volumetric DDoS protection.

WAF (Web Application Firewall)

CloudFront + AWS WAF:

resource "aws_wafv2_web_acl" "main" {
  name  = "my-waf"
  scope = "CLOUDFRONT"
 
  default_action {
    allow {}
  }
 
  rule {
    name     = "AWSManagedRulesCommonRuleSet"
    priority = 1
    override_action { none {} }
    statement {
      managed_rule_group_statement {
        name        = "AWSManagedRulesCommonRuleSet"
        vendor_name = "AWS"
      }
    }
    visibility_config {
      cloudwatch_metrics_enabled = true
      metric_name                = "CommonRuleSetMetric"
      sampled_requests_enabled   = true
    }
  }
  # ... visibility_config
}

AWS WAF charges $5/month per rule group + $0.60 per million requests. Gets expensive with many rules.

Cloudflare WAF: Included in Pro plan ($20/month). OWASP rules, custom rules, rate limiting all included. Much simpler to configure via UI or Terraform.

Integration with AWS Services

CloudFront wins here — it integrates natively with:

• S3: Direct origin, OAC (Origin Access Control)
• ALB/API Gateway: Seamless backend connection
• Lambda@Edge: Run code at the edge
• CloudFront Functions: Lightweight JS at edge (faster, cheaper than Lambda@Edge)
• ACM: Free SSL certificates, auto-renew
• CloudWatch: Built-in metrics without extra setup

Cloudflare can sit in front of AWS too, but the integration is less native. You'd have Cloudflare → CloudFront → ALB which adds complexity.

SSL/TLS

CloudFront: Free SSL via ACM (AWS Certificate Manager). Auto-renewal. Supports custom domains. TLS 1.2/1.3.

Cloudflare: Free SSL on all plans via Universal SSL. Zero configuration — just point your DNS to Cloudflare and SSL works. Also handles SSL between Cloudflare and your origin (Full SSL mode).

Both are great. Cloudflare is arguably simpler — literally one click.

Cache Configuration

CloudFront cache policy:

# Terraform
resource "aws_cloudfront_cache_policy" "default" {
  name        = "my-cache-policy"
  default_ttl = 86400    # 1 day
  max_ttl     = 31536000 # 1 year
  min_ttl     = 0
 
  parameters_in_cache_key_and_forwarded_to_origin {
    enable_accept_encoding_brotli = true
    enable_accept_encoding_gzip   = true
    cookies_config { cookie_behavior = "none" }
    headers_config { header_behavior = "none" }
    query_strings_config { query_string_behavior = "none" }
  }
}

Cloudflare cache rules (simpler):

• Configure via UI or API in minutes
• Page Rules: "Cache everything at .example.com/static/"
• Cache-Control headers respected automatically

When to Use Both Together

Some teams use Cloudflare in front of CloudFront:

• Cloudflare for DDoS protection, global anycast routing, and WAF
• CloudFront for tight AWS integration and Lambda@Edge

But this adds complexity and can cause cache confusion. Only do this if you have a specific reason (e.g., Cloudflare for DDoS + CloudFront for S3 static site hosting).

Feature Comparison

Verdict

AWS-native teams: CloudFront. The deep integration with S3, ALB, Lambda@Edge, and WAF makes it the natural choice.

Everyone else or security-first teams: Cloudflare. Better DDoS, simpler setup, generous free tier, and works regardless of where your backend lives.

Both are production-proven at massive scale. Wrong choice is rare here — either works.
