MTube Architecture

This project implements a simplified video platform clone with core functionality. The architecture is designed for simplicity and scalability, utilizing various Google Cloud services.

Key Components:

1. Video Storage: Google Cloud Storage

   • Hosts raw and processed videos

2. Video Upload Events: Cloud Pub/Sub

   • Manages video upload events for asynchronous processing

3. Video Processing: Cloud Run

   • Workers that transcode videos using ffmpeg

4. Video Metadata: Firestore

   • Stores processed video metadata

5. Video API: Firebase Functions

   • Handles video uploads and metadata retrieval

6. Web Client: Next.js / Cloud Run

   • User interface for video upload and viewing

7. Authentication: Firebase Auth

   • Manages user authentication with Google Sign-In

Key Features:

• Google account sign-in/out
• Video upload for authenticated users
• Video transcoding to multiple formats
• Listing and viewing uploaded videos (authenticated and unauthenticated)

This architecture provides a scalable foundation for a video sharing platform, with room for future enhancements and optimizations.
