Building an n-tier layered architecture

In n-tier architecture (also known as multitier architecture), you need to apply loosely coupled design principles and attributes of scalability and elasticity. In n-tier architecture, you divide your product functions into multiple layers, such as presentation, business, database, and services, so that each layer can be implemented and scaled independently.

With n-tier architecture, adopting new technologies and making development more efficient is easy. This layered architecture provides the flexibility to add new features in each layer without disturbing the features of other layers. In terms of security, you can keep each layer secure and isolated from the others, so if one layer gets compromised, the other layers won’t be impacted. Application troubleshooting and management also become manageable as you can quickly pinpoint where an issue is coming from and which part of the application needs to be troubleshot.
