Layered architecture increases flexibility, maintainability, and scalability. In Layered architecture, we separate the user interface i. Separation of concerns among these logical layers and components is easily achieved with the help of layered architecture. Multiple applications can reuse the components. The layered architecture allows us to reuse the same components in multiple applications.
For example, if we want a windows user interface rather than a web browser interface, this can be done very easily just by replacing the UI component. All the other components like business logic, data access logic and the database remains the same. N-tiers architectue usually have atleast three separate logical parts,each located on separate physical server. Each tier is responsible with specific functionality. Each tier is completely independent from all other tier, except for those immediately above and below it.
Communication between tiers is typically asynchronous in order to support better scalability. The main benifit of tier achitecture styles are 1. Because each tier is independent of the other tiers, updates or changes can be carried out without affecting the application as a whole. Because tiers are based on the deployment of layers, scaling out an application is reasonably straightforward.
