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

\text{MTBF} = \frac{\text{Total Elapsed Time - Sum of Downtime}}{\text{Total Number of Failures}}


\text{MTTR} = \frac{\text{Total Maintenance Time}}{\text{Total Number of Repairs}}


Define reliability as a core non-functional characteristic in System Design, measuring consistent performance over time. Learn to quantify system reliability using key metrics like MTBF and MTTR. Understand the critical distinction between reliability and availability in meeting service level objectives.
