Layered Architecture

Layered architecture is a popular design pattern that is widely used in software development. It provides a clear separation of concerns between different parts of the application and promotes modularity, scalability, and maintainability.

In a layered architecture, each layer has a specific responsibility and is loosely coupled with the layers above and below it. This means that changes in one layer should not affect the other layers, and each layer can be replaced or modified without affecting the overall architecture. This makes the application easier to understand, test, and maintain.

Let's take a closer look at the different layers in a typical layered architecture for a Spring Boot application:

In a layered architecture, each layer is responsible for a specific aspect of the application and should not depend on any other layers except for the layer immediately beneath it. This promotes modularity and makes the application easier to test and maintain.
