Software Architecture

With this skill, you design the global architecture of business software solutions and clearly visualize it. This includes identifying main components and layers (e.g., presentation layer, business logic layer, data access layer, integration services, security components, and external interfaces) and documenting how these interact with each other. The result is a comprehensive blueprint of the enterprise solution.

The importance of this is that all team members and stakeholders gain insight into the structure of the application before implementation begins. This makes collaboration easier (everyone understands where certain functionality belongs) and changes or additions can be implemented with minimal impact on the overall system. Well-designed architecture also ensures that the solution can scale with growing business needs and integrate with existing enterprise systems.

Starting Points

Key Points

  • You divide the application into logical modules/components with clear responsibilities, demonstrating understanding of separation of concerns and business domain boundaries.
  • You create schematic overviews (such as UML component diagrams or the C4 model) of the software architecture. This shows which components exist and how data flows between these components to support business processes.
  • You justify architectural choices based on business requirements, scalability needs, security considerations, and integration with existing systems.
  • You apply common enterprise architecture patterns where relevant (e.g., microservices, event-driven architecture, API gateway pattern) and can explain their benefits in business contexts.
