What is Availability?

Concept Explanation Availability, in the context of system design, refers to the measure of a system’s uptime—the percentage of time it remains operational and accessible to perform its intended functions under normal or anticipated conditions. It is a critical metric…

What is Scalability?

Concept Explanation Scalability, within the realm of system design, denotes the ability of a system to accommodate an increase in demand—such as a surge in user traffic, transaction volume, or data processing requirements—while maintaining acceptable levels of performance, reliability, and…

9 Software Architecture Patterns Every Developer Should Know

Software architecture patterns provide proven blueprints for structuring applications, guiding developers in building scalable, maintainable, and efficient systems. These patterns address common challenges in design, such as modularity, performance, and extensibility. This in-depth exploration examines nine essential patterns, including layered,…

Stateful vs Stateless Architecture: A Comparative Analysis

Introduction Stateful and stateless architectures represent two distinct paradigms in system design, each with significant implications for scalability, complexity, and operational efficiency. Stateful architecture maintains client session data or application state on the server, while stateless architecture treats each request…

What’s an API?

Introduction Application Programming Interfaces (APIs) are fundamental building blocks in modern software architecture, serving as the conduits for communication between different system components. In the context of system design interviews, understanding APIs is essential, as they often form the backbone…

How Interviewers Evaluate System Design Answers

Introduction System design interviews are a pivotal component of the hiring process for software architect and senior engineering roles, testing a candidate’s ability to architect scalable, reliable, and efficient systems under complex constraints. Unlike coding interviews, which focus on algorithmic…

What is System Design and Why it Matters in Interviews

Introduction System design is a cornerstone of modern software engineering, encompassing the art and science of architecting scalable, reliable, and efficient systems to solve complex problems. In the context of technical interviews, particularly for software architect or senior engineering roles,…
