Good architecture is invisible when it's working well, but becomes painfully obvious when it's not. Learn how to design systems that remain maintainable as they grow.
## Principles of Maintainable Architecture
Follow these core principles for lasting architecture:
- **Single Responsibility:** Each component has one clear purpose
- **Loose Coupling:** Components are independent and replaceable
- **High Cohesion:** Related functionality is grouped together
- **Abstraction:** Hide complexity behind clear interfaces
- **Consistency:** Follow patterns throughout the system
## Architecture Metrics That Matter
Measure these indicators of architectural health:
- **Cyclomatic complexity:** How complex your code paths are
- **Coupling metrics:** How tightly connected your components are
- **Cohesion scores:** How well-organized your modules are
- **Dependency depth:** How many layers of dependencies you have
- **API stability:** How often your interfaces change
## Evolutionary Architecture Strategies
Build systems that can evolve over time:
- **Modular design:** Independent components that can be updated separately
- **Interface versioning:** Manage changes without breaking existing code
- **Incremental migration:** Gradually improve architecture without big rewrites
- **Fitness functions:** Automated checks for architectural compliance
## Common Architecture Antipatterns
Avoid these architectural mistakes:
- **The Big Ball of Mud:** Lack of clear structure or organization
- **Spaghetti Code:** Complex interdependencies throughout the system
- **God Objects:** Classes or modules that do too much
- **Leaky Abstractions:** Implementation details exposed through interfaces
