Build a Video Streaming App like YouTube | AWS, FastAPI, Docker, Redis, Flutter | System Design

Let's build a simple yet powerful video streaming app similar to YouTube using Amazon Web Services (AWS), FastAPI, Docker, Redis, PostgreSQL, Flutter and Bloc! This tutorial is designed for beginners in AWS, Docker or PostgreSQL. Since our main focus of the tutorial will be backend development, if you're more comfortable with a different frontend framework—or just want to follow along purely for backend knowledge—feel free to use your preferred tools. 📌 Discord Server -   / discord   GitHub Repository - https://github.com/RivaanRanawat/vide...
