Advantages of System Design

System Design is the process of defining the architecture, components, interfaces, and data flow of a system to meet user and business requirements. It is a core concept in software engineering and distributed systems and is commonly asked in interviews at companies like , , ,

• It defines how different components, modules, and services of a system interact with each other.
• It focuses on important aspects such as scalability, load balancing, caching, performance, reliability, and maintainability.
• It provides a blueprint for building efficient systems that can handle large numbers of users and requests.

Example: Designing a social media platform like Instagram involves creating components such as databases, load balancers, caching systems, and user services to support millions of users efficiently.

Benefits and Advantages of System Design
