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).
