What is Clean Architecture?

Levels of Architectural Abstraction

System : the most abstract representation of software

Sub-system : System can be represented as a set of one or more subsystems

Layers : Sub-systems are typically divided into one or more layers

Components : Layers are often subdivided into one or more components

Classes : Components contain classes

Data and Methods : Classes contains data and methods

What is Bad Architecture?

Complex

Incoherent : the parts don't seem like they fit together

Rigid : hard to change or evolve the architecture

Brittle : touching a part of the code over here might break another part of the code somewhere else

Untestable

==> Unmaintainable

What is Good Architecture?

Simple

Understandable

Flexible

Emergent

Testable

==> Maintainable

What is Clean Architecture?

Architecture that is designed for the inhabitants(User, developers who building or maintaining the system) of the architecture. Not for the architect or the machine. Clean architecture is a philosophy of architectural essentialism. It's about focusing on what is truly essential to the software's architecture versus what is just an implementation detail.

Focus on the essential

Build only what is necessary

Optimize for maintainability

Context is king

All decisions are a tradeoff

Align with business goals

Use your best judgement
