Three-Tier Architecture Diagram - Visual Guide for Developers & Engineers #3476635 (License: Personal Use)

This schematic depicts a standard three-tier architecture with distinct horizontal layers: the bottom tier represents the data layer (e.g., databases), the middle tier houses application logic (APIs, services), and the top tier shows the presentation or client interface. Each layer is separated by clear boundaries, emphasizing modularity, scalability, and maintainability in enterprise software systems.

Used in technical documentation, cloud architecture guides, software engineering tutorials, and DevOps training materials to explain layered system design; targets developers, solution architects, and IT students seeking foundational knowledge of scalable application structures.
