Course Overview

This comprehensive course covers both Low-Level Design (LLD) and High-Level Design (HLD), ideal for software engineers aiming to crack system design interviews or enhance their architectural thinking. Learn how to build scalable, maintainable, and efficient systems using real-world use cases.

Modules Covered

Module 1: Introduction to System Design

• Understanding the need for System Design
• HLD vs LLD
• Real-world examples and expectations in interviews

Module 2: High-Level Design (HLD)

• Designing for scalability and availability
• System requirements and constraints
• Monolithic vs Microservices architecture
• Load balancers, caching, CDNs
• Databases: SQL vs NoSQL
• CAP Theorem and Consistency models
• Designing APIs (REST, GraphQL)

Module 3: Designing Common Systems (HLD Projects)

• URL Shortener (like Bitly)
• Messaging Queue System (like Kafka)
• File Storage System (like Google Drive)
• Social Media Feed (like Facebook/Twitter)
• Video Streaming Service (like YouTube)
• Ride-Sharing App (like Uber)
