What is Tier 2 vs Tier 3 architecture

Why is it called N-tier architecture
The “N” in the name n-tier architecture refers to any number from 1. Not only does your software gain from being able to get services at the best possible rate, but it's also easier to manage. This is because when you work on one section, the changes you make will not affect the other functions.
Is 3-tier architecture monolithic

Is MVVM 3-tier architecture
MVVM is a framework for making applications in WPF. MVVM is the same as the MVC framework. It is a 3-tier architecture plus one more layer. We can do loose coupling using MVVM.
Is Microservices a 3-tier architecture

What is the difference between n-tier and N layer
These are referred to as the 3 tiers of your application. So they may be n in number and so the term n-tier application. So tiers are the physically separate components of the same system. On the other hand, layers refer to the internal architecture of your component.
Why 3 tier is better than 2 tier architecture
The three-tier DB architecture does not allow its clients and database to communicate directly- thus making it comparatively more secure in the long run.

What are types of tier architecture

Which tier architecture is best
The n-tier architecture is an industry-proven software architecture model. It is suitable to support enterprise level client-server applications by providing solutions to scalability, security, fault tolerance, reusability, and maintainability. It helps developers to create flexible and reusable applications.
