Study Notes
Definition of Systems Architecture
- Structural design that organizes components, interactions, and relationships within a system.
- Represents both existing systems and systems to be created.
- Focused on internal interfaces among components and the interface with the external environment.
Key Elements of Systems Architecture
- Components: Building blocks, major functional units performing specific tasks.
- Interactions: Communication and information exchange among components.
- Relationships: Connections and dependencies between components crucial for coherent design.
Components
- Represent major functions, can include software modules, hardware devices, and subsystems.
- Examples include:
- User Interface (UI)
- Database Management System (DBMS)
- Authentication Service
- Payment Gateway
- Business Logic Module
Interactions
- Involve data exchange, function invocation, and response triggering between components.
- Aim for seamless collaboration to achieve desired system outcomes.
Types of Interactions
- Example interactions include:
- User form submission triggering requests to the backend server.
- Backend server communication with the database for data management.
- Inter-component message exchange via APIs or protocols.
Relationships in Systems Architecture
- Describe how components connect and depend on each other.
- Types of relationships include:
- Dependency: One component relies on another's functionality.
- Association: Components work together for a specific purpose without strong dependencies.
- Aggregation: Components form a larger unit, composed of other components.
- Composition: Tightly integrated components forming an inseparable whole.
Architectural Styles
-
Monolithic Architecture: The application is a single unit.
- Examples: Traditional desktop applications, Content Management Systems (e.g., WordPress, Drupal).
-
Client-Server Architecture: Divides the system into client and server components.
- Examples: Web browser accessing a website, online gaming.
-
Microservices Architecture: Breaks the system into small, independent services communicating through APIs.
- Example: E-commerce platforms with separate services for user authentication, product catalog, video streaming, and payment processing (e.g., Netflix, Amazon).
