How I Hosted My First Production Site for ₹0: AWS + Cloudflare Setup

Running a project on localhost is straightforward. But the moment you try to deploy something real : with a custom domain, HTTPS, and a scalable architecture ,you realize how many moving parts are actually involved. For my project IPlusFlow (an EEG-based Alzheimer’s detection platform), I needed a setup that was secure, scalable, and mirrored real industry architecture. Most importantly, I wanted to run it entirely for free.

The Architecture Strategy The goal was to build a production-style design that strictly separated storage, compute, and traffic routing. Putting everything in one place is easier, but separating concerns scales better. Backend: FastAPI running on AWS Lambda via API Gateway Frontend: Static files hosted on Amazon S3 CDN: AWS CloudFront
