Design Microservices Architecture with Patterns and Principles - What Is Clean Architecture?

Clean Architecture, created by Robert Martin, is a software design pattern that organizes code by separating business logic from implementation details. It emphasizes keeping core business logic independent of presentation and data access layers, allowing flexibility in changing technologies. Clean Architecture is divided into policies (business rules) and details (implementation code), focusing on policies first before choosing databases or frameworks. This approach ensures that internal layers remain independent of third-party libraries, while outer layers handle actual implementation.

What is the primary purpose of Clean Architecture?

• To focus on database selection at the start

• To lock in specific third-party libraries

• To integrate business logic with presentation layers

• To organize code by encapsulating business logic in inner circles

What are the two main elements of Clean Architecture?

• Policies and frameworks

• Details and databases

• Policies and details

• Frameworks and tools

In Clean Architecture, what do policies represent?

• User interface designs

• Database schemas

• Implementation code

• Business rules and procedures

Why is it beneficial for internal layers to be independent of third-party libraries?

• To reduce the cost of development

• To ensure faster development

• To allow flexibility in using different frameworks and tools

• To increase dependency on specific technologies

What do the outer layers in Clean Architecture depend on?

• Inner layers and third-party tools

• Only third-party tools

• Business logic

• Presentation layers
