System Design Fundamentals

Learn System Design: Master Scalability, Caching, Databases, and Performance Optimization

What you'll learn

Grasp Core Concepts: Understand scalability, availability, and latency to design robust systems

Build Scalable Architectures: Use load balancing, caching, and sharding for high-traffic systems.

Select Databases: Choose SQL vs. NoSQL and storage solutions based on system needs.

Optimize Performance: Identify bottlenecks and enhance system reliability and speed.

Requirements

The System Design Fundamentals course is designed to be accessible for beginners while providing value to those with some technical background. There are no strict prerequisites, but the following will help learners get the most out of the course: Basic Programming Knowledge: Familiarity with any programming language (e.g., Python, Java, or JavaScript) is helpful for understanding examples, but no advanced coding is required. Understanding of Software Development Basics: A general idea of how web applications or software systems work (e.g., client-server model, APIs) will aid comprehension. Curiosity and Problem-Solving Mindset: No prior system design experience is needed—just a willingness to learn and tackle design challenges. No Specialized Tools Required: Lectures are conceptual and use diagrams; a computer with internet access is sufficient for accessing course materials and exercises.
