Introduction
In the following report, the n tier architecture has been explained and evaluated. It has
been compared with the traditional model to highlight its advantages. The internet
applications of this architecture has been discussed as well in the subsequent sections of the
report.
Discussion
The N-tier architecture
The n-tier architecture is a software engineering architecture that physically and
logically separates the data management, processing and presentation functions from the
application. As there is no resource sharing, these functions can run separately on different
clusters and machines at their maximum capacity. Separating the functions from the
applications makes management easier as no function can affect the other function due to
their isolation (Bilal et al. 2013). Moreover, isolation of an issue in the application becomes
easier due to this architecture. The n tier architecture or multi-tier architecture generally
divides the application into three functions namely data tier, logic tier and presentation tier.
Unlike the framework of MVC or Model view controller, this concept physically
divides the application into separate parts. Another particular difference from the MVC
framework is that the n tier architecture uses a middle layer known as the logic tier to
maintain its communication among all the layers. In MVC, the communication is naturally
triangular where the model, controller and view layer are interconnected (Sarker & Apu,
2014). Still, the traditional MVC layer can be used in the presentation tier in a total n tier
architecture, concluding that both the frameworks are not mutually exclusive.
