The goal is to help developers fully understand browser caching and optimize website performance.

This article delves into the core distinctions between "Layers" and "Tiers" in software architecture. Layers refer to the logical organization of code, such as presentation, business, and data layers, focusing on functional separation without regard to runtime environment. Tiers, on the other hand, represent the physical deployment locations of these logical layers, such as different computers or processes. Drawing on Rockford Lhotka's insights, the paper explains how to correctly apply these concepts in architectural design, avoiding common confusions, and provides practical code examples to illustrate the separation of logical layering from physical deployment. It emphasizes that a clear understanding of layers and tiers facilitates the construction of flexible and maintainable software systems.
