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,…

Introduction Concurrency and parallelism are fundamental concepts in system design that address how tasks are executed within software and hardware environments. While often used interchangeably, they represent distinct approaches to managing multiple operations, with significant implications for performance, scalability, and…

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…

Introduction Client-server architecture is a foundational model in distributed computing, underpinning the design of modern software systems, including web applications, enterprise solutions, and networked services. This architecture delineates the roles of clients and servers, where clients initiate requests, and servers…

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…

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…

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,…
