High-Level System Design involves creating a blueprint for complex systems, focusing on architecture, component interactions, and scalability. It addresses how different parts of a system communicate, manage data, and handle user requests efficiently.

We just published a course on the freeCodeCamp.org YouTube channel about high-level system design. This course offers a unique hands-on approach to understanding high-level system design (HLD) concepts by building a fully functional YouTube-like platform. Keerti Purswani developed this courese.

What is High-Level System Design?

High-Level System Design involves creating a blueprint for complex systems, focusing on architecture, component interactions, and scalability. It addresses how different parts of a system communicate, manage data, and handle user requests efficiently.

Course Overview

In this course, you will start with a basic system flow and gradually incorporate three key services: upload, watch, and transcoder. Each service is important to building a scalable and robust video platform. Here’s a detailed look at what you will learn:

  1. Upload Service: Learn how to handle video uploads effectively, including chunking and managing large file transfers.
  2. Transcoder Service: Dive into transcoding with FFmpeg, a powerful tool for converting video formats and optimizing videos for different devices.
  3. Watch Service: Implement Adaptive Bitrate Streaming using HLS (HTTP Live Streaming) to ensure smooth playback across various network conditions and devices.

Technologies Covered

This course leverages a range of modern technologies to build the YouTube clone:

  • Front-end: JavaScript and React for creating dynamic user interfaces.
  • Back-end: Node.js and Express for building scalable server-side applications.
  • Database: Prisma as an ORM (Object-Relational Mapping) tool to interact with databases.
  • Frameworks: Next.js for server-side rendering and improved performance.
  • Other Tools: Docker for containerization and Redis for caching to enhance performance and scalability.

By the end of this course, you will have a deep understanding of high-level system design principles and practical experience in building a complex application. Watch the full course on the freeCodeCamp.org YouTube channel (2-hour watch).
