Understanding Architectural Layers in Software Systems

Modern software systems are complex by nature — they must handle scalability, performance, maintainability, and rapid change. To manage this complexity, architects and developers often organize their applications into architectural layers. Layered architecture provides a structured way to separate concerns, simplify maintenance, and enable scalability.

In this article, we’ll explore what architectural layers are, why they matter, and how they fit together in a typical software system.
