Cloudflare vs AWS CloudFront: What I Check Before Picking a CDN

A practical Cloudflare vs CloudFront checklist for operators: cache control, pricing surprises, WAF fit, and when AWS lock-in is worth it.

Start Here

TL;DR

  • Pick Cloudflare when you want fast setup, WAF defaults, and edge features without living inside AWS billing.
  • Pick CloudFront when your origin, IAM, and logs already live in AWS and you need tight CloudWatch integration.
  • Do not switch CDNs on a marketing chart alone. Test cache hit ratio, purge time, and TLS/cert workflow on one real property first.

Cloudflare vs AWS CloudFront: What I Check Before Picking a CDN - seo guide from Tech Revenue Brief

I would not pick Cloudflare or CloudFront from a feature matrix. Both can make a site faster. The wrong one makes billing, purges, and security rules harder than they need to be.

Choose Cloudflare if you want a CDN plus WAF and DNS in one place with less AWS ceremony. Choose Amazon CloudFront if your stack is already deep in AWS and you care more about IAM, S3 origins, and CloudWatch than a polished admin UI. Validate with one production-like property before you move traffic.

What I compare first

Side-by-side analysis of CloudFront and Cloudflare, focusing on CDN performance and pricing.

I start with four boring checks:

  • Where the origin lives today
  • Who will touch cache rules after launch
  • How purge and rollback work under pressure
  • Whether security rules need a separate product

If your site already sits on S3 or behind an ALB, CloudFront often wins on wiring. If you are tired of AWS console hopping and want DNS, CDN, and bot controls together, Cloudflare usually feels cleaner.

Cache and purge reality

Guide on selecting the right CDN, comparing AWS CloudFront and Cloudflare's capabilities.

CDN demos love TTFB screenshots. Operators care about bad deploys.

I ask: how fast can we purge a poisoned asset? How do we version hashed JS? Can a junior engineer undo a bad cache rule without paging the whole team? Cloudflare's dashboard is usually faster for that. CloudFront is fine if your team already automates invalidations in CI.

Pricing surprises

Both look cheap until you misconfigure origin fetch, image transforms, or high-churn APIs. I estimate:

  • Bandwidth at expected peak
  • Request volume for APIs and HTML
  • WAF / bot / image costs as separate lines

Then I add 20% for "we will misconfigure something in month one."

When I refuse to switch

If the only reason is "everyone says Cloudflare is better," I wait. A CDN migration that breaks cookies, auth headers, or stale HTML is not a win. Run a shadow property, compare cache hit ratio for a week, then cut over.
