Scalability & System Design for Developers

This module provides a bottom-up approach to design scalable systems. First, we’ll learn about the building blocks of modern systems, with each component being a completely scalable application in itself. We'll then explore the RESHADED framework for architecting web-scale applications by determining requirements, constraints, and assumptions before diving into a step-by-step design process. Finally, we'll design several popular services by using these modular building blocks in unique combinations.

This module will give you an alternative perspective on modern system design and empower engineers, architects, and product managers to dive deep into complex problems. By the end of this module, we'll be prepared to design bigger systems capable of scaling with users and maintaining availability.
