The Modern Software Stack.md

• Here are 9 layers that make up most modern applications:
  1. Presentation Layer (UI/UX): Handles how users interact with the application, focusing on visuals, layout, and usability.
  2. Edge and Delivery (Optional): Brings content closer to users through global delivery networks, reducing latency and improving performance.
  3. Integration Layer (API): Defines how different parts of the system communicate, enabling interoperability between components.
  4. Messaging & Async Processing (Optional): Processes tasks and events in the background to improve scalability and responsiveness.
  5. Business Logic Layer: Implements the core rules, workflows, and decision-making processes of the application.
  6. Data Access Layer: Acts as a bridge between application logic and stored data, ensuring secure and efficient retrieval or updates.
  7. Data Storage Layer: Stores, organizes, and manages the application’s structured and unstructured data.
  8. Analytics & ML (Optional): Analyzes data to generate insights, predictions, and intelligent features.
  9. Infrastructure Layer (Hosting / Runtime): Provides the computing environment and resources for deploying, running, and scaling the application.
