When should I use layered architecture in software development?

What is layered architecture and when should I use it?

Layered architecture is a design pattern that separates concerns into different layers. You should use it when you need to manage complexity, improve maintainability, and enhance scalability.

Can you give me an example of a project that would benefit from this architecture?

Sure! A web application with a user interface, business logic, and data access layers would benefit greatly from layered architecture.

Are there any downsides to using layered architecture?

Yes, it can introduce overhead and complexity, especially if the layers are not well-defined or if communication between layers is inefficient.

How do I decide the number of layers to implement?

The number of layers should be based on the project's complexity and requirements. Start with a few essential layers and add more as needed.
