The top 5 software architecture patterns: How to make the right choice

We learned about Model-View-Controller in class but there are more software architecture patterns, there are different layer is useful for different design. This blog is based on the book Software Architecture Patterns, by Mark Richards, Boston-based software architect who’s been more than 30 years about how data should flow through software. The author made top 5 software architecture patterns, which show how to choose them.

Layered (n-tier) architecture, this architecture arranged so the data enters the top layer and works its way down each layer until it reaches the bottom, which is usually a database. This is where the Model-View-Controller (MVC) structure, as we know, is the standard software development approach offered by most of the popular web frameworks, is clearly a layered architecture. Best use for: New applications that need to be built quickly, enterprise or business applications that need to mirror traditional IT departments and processes and applications requiring strict maintainability and testability standards.

Event-driven architecture helps manage this by building a central unit that accepts all data and then delegates it to the separate modules that handle the type. This architecture is easily adaptable to complex, often chaotic environments, scale easily and easily extendable when new event types appear. This type of architecture best for asynchronous systems with asynchronous data flow, applications where the individual data blocks interact with only a few of the many modules.

Microkernel architecture, the basic routines for displaying a file and editing it are part of the microkernel. The solution is to push some basic tasks—like asking for a name or checking on payment—into the microkernel. Good use for this architecture is the applications with a clear division between basic routines and higher order rules and the applications with a fixed set of core routines and a dynamic set of rules that must be updated frequently.

Microservices architecture, the goal is to create a number of different tiny programs and then create a new little program every time someone wants to add a new feature. It’s used mainly when the different tasks are easily separated. In many cases, different tasks can require different amounts of processing and may vary in use. Best use for this is websites with small components, rapidly developing new businesses and web applications.

This is interesting architecture layers type, it is important to know and compare to real life application. I hope we more type to know more about the architecture, specially about website.
