Modular Technology Stack Illustration | Layered Architecture Concept #3615614 (License: Personal Use)

This isometric graphic depicts a three-tier architecture model using stacked rectangular blocks in distinct colors: light blue (top), lime green (middle), and terracotta red-orange (bottom). The top blue layer features two circular raised elements resembling connectors or APIs, suggesting integration points. The design conveys modularity, scalability, and separation of concerns common in modern software and infrastructure design.

Commonly used in technical documentation, SaaS product pages, developer blogs, or cloud architecture diagrams to visualize layered systems such as frontend/backend/database, microservices, or infrastructure-as-code stacks. Matches user intent seeking conceptual clarity on system design.
