N-tier application architecture

In order to understand N-tier applications and their potential for decoupling into microservices, we will hold its comparison against the monolithic style since both the development of N-tier applications and proliferation of microservices exist to address many of the problems found in the outdated conditions we've found resulting from the approach of monolithic architectures.

The N-tier application architecture, also referred to as distributed applications or multi-tier, proffers a model in which developers can create flexible and reusable applications. As the application is segregated into tiers, developers are empowered by the option of modifying or adding a specific tier or layer instead of requiring a rework of the entire application as would be necessary under monolithic. A multi-tier application is any application developed and distributed among more than one layer. It logically separates the different application-specific and operational layers. The...
