Key Components of System Design

Before diving into the details of system design, it's important to understand its key components, which form the foundation of a well-designed system. In system design, we focus on how to structure the architecture, ensure scalability, maintain optimal performance, and build strong security measures.

The table below outlines these essential components, offering a brief description of each and providing real-world examples to help you visualize how they apply in practice.

As we delve into the world of system design, our focus will primarily be on architecture. Understanding the architecture of a system is crucial because it sets the foundation for how different components interact and work together seamlessly.

In our discussions, we will use the e-commerce domain as a consistent example to illustrate key concepts. This will allow us to explore various architectural styles and principles in a practical context.
