2 million developers tapped AWS Free Tier last year alone. But here’s the kicker: one indie builder took it further, firing up a production EEG Alzheimer’s detector at eeg.iplusflow.com—custom domain, HTTPS everywhere, scalable backend—for a fat ₹0.
Picture this. Your localhost prototype buzzes along fine. Then reality hits: real users, file uploads, security layers. Suddenly, you’re wrestling DNS, certs, CDNs like a digital gladiator. That’s where IPlusFlow’s creator stepped in, wiring AWS and Cloudflare into a lean, mean, free machine. And yeah, it mirrors Big Tech stacks—Lambda backend, S3 statics, the works.
Why Bother with This Frankenstein Setup?
Separation of concerns. It’s the secret sauce. Dump everything in one bucket? Quick wins, sure. But scale hits, and boom—single point of failure. No thanks.
This rig splits it clean:
Backend: FastAPI on AWS Lambda, API Gateway fronting it.
Frontend: S3 static files.
CDN: CloudFront.
DNS maestro: Cloudflare.
Energy surges here. It’s like assembling a spaceship from scavenged parts—each piece free, interlocking perfectly.
Ditching Route 53: The Cost-Killer Move
Route 53? smoothly, yeah. But that monthly fee? Nope. Cloudflare swoops in as DNS overlord—for free.
Buy domain. Flip nameservers to Cloudflare. Route eeg.iplusflow.com and api.iplusflow.com like a boss. Boom. Zero recurring hits.
Simple. Impactful. Game over for paid DNS.
“To keep my infrastructure at exactly ₹0, I bypassed Route 53 entirely and handled DNS through Cloudflare.”
Spot on. That’s the dev mindset—question every charge.
The SSL Hell That Almost Sank It
Mumbai region (ap-south-1). Wildcard cert (*.iplusflow.com) generated there. API Gateway loves it.
CloudFront? Crickets. Cert vanishes from dropdown.
Dig docs. Truth bomb: CloudFront demands us-east-1 certs only. Duplicate it. Attach. Done.
Brutal AWS quirk. Feels like regional protectionism—your infra’s in India, but certs gotta bow to Virginia.
And Cloudflare proxy? Orange cloud on. SSL handshake fails instantly. Why? API Gateway and CloudFront already terminate HTTPS. Cloudflare muscles in—conflict city.
Grey cloud (DNS only). Fixed.
CORS: The Browser’s Petty Gatekeeper
Frontend fetches presigned S3 URLs from backend. API golden. Uploads? Blocked.
Subdomains = different origins. Browsers enforce it hardcore.
S3 CORS policy: Allow https://eeg.iplusflow.com, PUT method only. Click apply. Magic.
Here’s my unique twist—think back to 1999, when Netscape browsers threw CORS-like tantrums on hand-coded Perl CGI sites. Same battles, cloudier tools. History rhymes; manual deploys build muscle memory no PaaS can touch.
CloudFront + Cloudflare: Redundant or Rocket Fuel?
Cloudflare CDNs for days. Why CloudFront?
Two reasons, ironclad.
S3 stays private. No public bucket roulette. Origin Access Control locks it; CloudFront keys in.
SSL harmony. AWS certs play nice with CloudFront. Cloudflare-to-private-S3? SSL routing migraines await.
Flow: Cloudflare DNS → CloudFront CDN → private S3. Backend Lambda hums via API Gateway.
It’s a relay race—each leg optimized, zero drops.
Wonder hits: This isn’t just cheap hosting. It’s a blueprint for AI edge. EEG data uploads, CNN-BiLSTM crunching Alzheimer’s signals—all free. Democratizes health tech like Linux did servers in the ’90s.
Lessons That Scar but Strengthen
Request lifecycle demystified. DNS resolution. SSL termination points. CDN-storage dances.
Skip Vercel/Netlify one-clicks first time. Wrestle this beast. Emerge wiser.
Pitfalls? Cert regions. Proxy clashes. CORS precision. All public now, thanks to this GitHub repo: EEG-CNN-BiLSTM.
Live it: eeg.iplusflow.com. Poke api.iplusflow.com. See separation shine.
Bold call: In five years, zero-cost infra like this powers 80% of indie AI/ML pilots. No more gatekept clouds.

Frequently Asked Questions
How do I host a production site for free on AWS and Cloudflare?
Bypass Route 53 with Cloudflare DNS, Lambda + API Gateway backend, S3 + CloudFront frontend. Keep S3 private via OAC. Generate regional certs.
Does AWS free tier work for real production traffic?
Yes—for starters. Lambda’s 1M requests/month free. S3 egress via CloudFront stays cheap. Scales till you hit limits, then optimize.
What’s the catch with free AWS Cloudflare hosting?
Quirks like cert regions and proxy conflicts. But debuggable. No vendor lock beyond AWS ecosystem.
