Review system design fundamentals, including abstraction and non-functional characteristics in designing modern systems.

Deep Dive into System Design Interview

System design is the process of defining components and their integration, APIs, and data models to build large-scale systems. Mobile and cloud computing, combined with expanded internet access, make system design a core skill for the modern developer. This module provides a brief overview of the concepts required to design scalable systems.

System Design Essentials

Congratulations, you’ve successfully finished the module “System Design Essentials.”

## Summary
Starting with abstractions in general, we learned about the importance of abstraction, network abstractions and remote procedural calls, and the spectrum of consistency and failure models. We also learned about non-functional system characteristics and back-of-the-envelope calculations.

## What’s next?
It’s time to learn about the building blocks of modern systems, each component of which is a completely scalable application in itself.
