As a DevOps engineer, deploying a static frontend website on AWS S3 is a foundational cloud skill. I recently deployed my own frontend application using S3 Static Website Hosting, and this article documents the exact steps, configurations, and code I used — all in one place.
This is a real hands-on deployment, useful for DevOps interviews and portfolio projects.
🧠 What AWS S3 Is Used For (Interview Key Point)
