Scalable Notification System | System Design & Architecture Explained - System Design Project

This video presents the architecture and design of my Scalable Notification System, a microservices-based platform built to handle high-throughput notification delivery across multiple channels. In this presentation, I explain: * The problem behind modern notification systems * System architecture and design decisions * Event-driven communication using Apache Kafka * Priority-based notification processing * Multi-channel delivery (Email and SMS) * User preferences and duplicate prevention * Database schema and API design * Scalability strategies and rate limiting This system is designed using real-world distributed systems principles such as: * Microservices architecture * Asynchronous processing * Fault tolerance and resilience * Horizontal scalability * Decoupled service communication
