Cloudflare vs CloudFront: which CDN should you choose for your architecture?

For most teams, the answer fits in one sentence: choose Cloudflare if you operate across multiple clouds or want DDoS protection and a WAF included at no extra cost, and choose CloudFront if your infrastructure runs entirely on AWS and you benefit from free transfers from S3 or EC2.

Common scenarios can be decided quickly:

The main trade-off: Cloudflare offers predictable costs and included security; CloudFront offers native AWS integration and egress savings dependent on your origin architecture.

Cloudflare and CloudFront address distinct needs: Cloudflare leads on cost predictability, included security, and multi-cloud simplicity, while CloudFront wins only when origins are deeply integrated with AWS.

A few important clarifications after this table:

The two solutions start from opposing philosophies, and this difference shapes the entire FinOps analysis.

Cloudflare charges a monthly flat-rate plan. The Free plan covers standard caching without a bandwidth limit. The Pro plan, at a fixed monthly price, adds a managed WAF and advanced cache rules. The Business plan, also at a fixed monthly price, provides access to raw logs and stronger SLAs. Beyond that, Enterprise plans are negotiated individually. In every case, cached bandwidth is not billed, making monthly costs highly predictable for static workloads.

CloudFront is entirely usage-based: every gigabyte transferred and every thousand HTTP/HTTPS requests are billed according to a regional pricing schedule. The AWS free tier offers 1 TB of data transfer and 10 million requests per month for the first 12 months.

Pro tip: Before any PoC, collect three metrics for 30 days: data transfer volume (GB/month), request count (HTTP/HTTPS separately), and cache hit ratio. These three figures are enough to build a reliable comparative TCO in the AWS calculator and Cloudflare's pricing schedule. Without this data, any estimate remains speculative.

This gap is largely explained by the fundamental architectural difference between the two networks. Cloudflare uses anycast routing: the same IP address is announced simultaneously from hundreds of data centers, and traffic is absorbed by the nearest PoP without a DNS decision. CloudFront uses a hierarchical architecture with Edge Locations and intermediate Regional Edge Caches, introducing additional latency on cache misses.

Having 600 PoPs does not automatically mean lower latency than 335 cities. Coverage density in high-traffic areas (Western Europe, the US East Coast, Southeast Asia) and peering quality matter more than the raw number of points of presence.

The most significant difference for teams without a dedicated security budget:

The two approaches solve similar problems (personalizing responses close to users) but use very different execution models.

Cloudflare offers Logpush to export raw logs to Datadog, Splunk, Elastic, or an S3 bucket, available from the Business plan. Built-in analytics (Cloudflare Radar, Web Analytics) provides an immediate view without configuration. CloudFront integrates natively with CloudWatch for real-time metrics, Kinesis Data Firehose for log streaming, and S3 for archiving. If your team already operates within AWS, this integration is seamless; otherwise, it requires additional setup.

Three patterns dominate architecture decisions, each with its own adoption signals.

Pattern 1: Complete replacement with Cloudflare. Remove CloudFront and place Cloudflare directly in front of your origins (S3, EC2, on-premise servers). This pattern suits teams wanting to simplify their stack, reduce security costs, and improve operational visibility. The main drawback is losing free egress transfers from S3/EC2.

Pattern 2: Cloudflare in front of CloudFront. Cloudflare absorbs DDoS attacks, applies the WAF, and manages the global cache; CloudFront remains for Lambda@Edge integrations and AWS origins. This pattern potentially doubles latency on cache misses and complicates debugging, but lets you benefit from both ecosystems.

Pattern 3: Native CloudFront only. Stay in the AWS ecosystem, use Shield Advanced for security, Lambda@Edge for business logic, and CloudWatch for observability. Optimal when origins are 100% AWS and your team already knows Amazon's tools.

Most small teams come with the same question: “Do we really need to pay for a CDN?” The answer depends less on budget than on origin architecture. A startup whose website runs on an OVH or Hetzner VPS has no reason to use CloudFront: free egress transfers from S3 do not apply, and usage-based billing quickly becomes unpredictable as traffic rises.

The included WAF avoids adding a separate security budget line, and the interface is accessible to a team of two developers without a network specialist, particularly thanks to the best AI integrations for HubSpot and Pipedrive that facilitate marketing automation.

For SMEs that have already migrated to AWS, the calculation changes. When origins are on S3 and EC2, CloudFront does reduce the egress bill. But as soon as those teams add a WAF (AWS WAF), Shield Advanced, and Lambda@Edge, monthly costs often exceed a Cloudflare Business plan, with greater operational complexity.

Pharelia's consistent recommendation before choosing any CDN is to measure the current cache hit ratio and actual egress volume. Without those two figures, any pricing comparison remains theoretical. A CDN's impact on Core Web Vitals, and therefore on search visibility, is real, but only materializes with correct cache configuration, often the weak point in rushed migrations.

Choosing between Cloudflare and CloudFront without real traffic data means optimizing in a vacuum. Pharelia performs a complete technical infrastructure audit: current cache hit ratio analysis, origin mapping, comparative TCO estimation over 12 months, and identification of compliance risks (GDPR, data residency).

In practice, the support covers an instrumented PoC (before/after TTFB, cache, and egress metrics), a cutover runbook with rollback criteria, and a concise FinOps report you can present to management. You leave with figures rather than generic recommendations. For teams also wanting to measure technical performance's impact on visibility in AI engines, Pharelia includes AI citation tracking in the same system.

The following sources were used to build this analysis:

The closest alternatives are Fastly, Akamai, and AWS CloudFront. Fastly targets developer teams with powerful edge compute; Akamai serves large enterprises with strict compliance requirements; CloudFront remains the reference for AWS-native architectures.

Cloudflare includes WAF and DDoS protection in all paid plans at no extra cost and does not charge for cached bandwidth. For multi-cloud teams or sites with heavy static traffic, monthly costs are more predictable and often lower than CloudFront with WAF and Shield Advanced.

CloudFront bills by usage: around $0.085/GB transferred to Europe. The AWS free tier covers 1 TB of transfer and 10 million requests per month for the first 12 months. Costs rise quickly once you add AWS WAF (~$5/month per WebACL) and Shield Advanced, a paid option for advanced protection.

Cloudflare's Free plan serves as an entry point into its ecosystem: it covers caching, SSL, and basic DDoS protection without a bandwidth limit on cached content. Monetization relies on Pro, Business, and Enterprise plans, which add managed WAF, raw logs, stronger SLAs, and advanced features such as Argo Smart Routing or Workers.

Yes, the “Cloudflare in front of CloudFront” pattern is documented and used in production. Cloudflare absorbs attacks and applies the WAF upstream; CloudFront manages Lambda@Edge integrations and AWS origins downstream. This pattern adds operational complexity and latency on cache misses, but combines both solutions' strengths.
