Independence
Independence in system design refers to the ability of system components (modules, services, or subsystems) to function, develop, and scale with minimal or no dependency on others.
Types of Independence
| Type | Description | Example |
|---|---|---|
| Functional Independence | Each module performs a specific task without relying heavily on others. | Logging module, Payment processing |
| Deployment Independence | Components can be deployed separately. | Microservices |
| Scaling Independence | Only the parts that need more resources are scaled. | Independent services for search, analytics |
| Failure Independence | A crash in one part doesn’t bring down the rest. | Docker containers running isolated apps |
| Development Independence | Teams can build and release different modules at different times. | Frontend and backend teams working separately |
