Sunomi: A Cloud-Native Video Sharing Platform

Sunomi is a cloud-native video sharing platform, designed and built as a project for the Cloud Computing course at the University of Pavia. It mirrors the core functionalities of popular video-sharing services, enabling users to upload, share, and interact with video content, while leveraging the power and scalability of Amazon Web Services (AWS). This project demonstrates a deep understanding of cloud computing best practices, microservices architecture, serverless technologies, and DevOps principles.

Architecture

Sunomi is built on a microservices architecture, deployed on AWS. Key components include:

• Frontend: A single-page application (SPA) built with React and TypeScript, using Vite for development and bundling. Hosted on S3 and served via CloudFront.
• Controller: The backend API, built with Node.js and Fastify. Provides RESTful endpoints for all platform functionalities. Deployed on ECS Fargate.
• Transcoder: Responsible for transcoding uploaded videos into multiple HLS streams. Implemented in Python using FFmpeg. Deployed as on-demand ECS Fargate tasks triggered by S3 events and managed by Lambda and SNS.
• Database: MySQL database hosted on AWS RDS (Aurora MySQL in production, single instance in development). Uses Prisma ORM for database interactions.
• Object Storage: Amazon S3 for storing video files, thumbnails, and transcriptions. MinIO is used for local development.
• Event-Driven Communication: AWS SNS (Simple Notification Service) and AWS Lambda are used for asynchronous communication and event-driven workflows.
• API Gateway: Managed WebSocket API for real-time updates.
• CloudFront: CDN for efficient content delivery of videos and the frontend application.
• Other AWS Services: Rekognition (content moderation), Transcribe (speech-to-text), Route 53 (DNS), Certificate Manager (SSL/TLS), Secrets Manager (secrets management), DynamoDB (WebSocket connection management).
