Learn How Senior Engineers Think About Systems

System Design is not about memorizing architecture diagrams. It is about learning how to reason about real systems, understand requirements, estimate scale, evaluate trade-offs, and make sound architectural decisions.

System Design Foundations is a free, practical mini-course designed for engineers who want to build a strong foundation in system design and prepare themselves for real-world architecture discussions and senior-level interviews.

In this course, you will learn:

&bull; How senior engineers approach system design problems 
&bull; A practical 7-step framework for solving system design problems 
&bull; Functional and non-functional requirements 
&bull; Requirements discovery and the right questions to ask 
&bull; Back-of-the-envelope estimation and capacity planning 
&bull; Vertical vs horizontal scaling 
&bull; Stateless vs stateful architecture 
&bull; Monolith vs microservices 
&bull; Availability, reliability and performance 
&bull; Security and cost considerations 
&bull; CAP theorem and its practical implications 
&bull; How to evaluate architectural trade-offs

The learning approach:

Concept &rarr; Architecture &rarr; Real-World Example &rarr; Trade-offs &rarr; Production &amp; Interview Thinking

This is the foundation for the advanced Modern System Design for the AI Era program.
