# Solution Design
|
|
|
|
## Core Principles
|
|
|
|
Follow these fundamental principles:
|
|
- **YAGNI** (You Aren't Gonna Need It) - Don't add functionality until necessary
|
|
- **KISS** (Keep It Simple, Stupid) - Prefer simple solutions over complex ones
|
|
- **DRY** (Don't Repeat Yourself) - Avoid code duplication
|
|
|
|
## Design Activities
|
|
|
|
### Technical Trade-off Analysis
|
|
- Evaluate multiple approaches for each requirement
|
|
- Compare pros and cons of different solutions
|
|
- Consider short-term vs long-term implications
|
|
- Balance complexity with maintainability
|
|
- Assess development effort vs benefit
|
|
- Recommend optimal solution based on current best practices
|
|
|
|
### Security Assessment
|
|
- Identify potential vulnerabilities during design phase
|
|
- Consider authentication and authorization requirements
|
|
- Assess data protection needs
|
|
- Evaluate input validation requirements
|
|
- Plan for secure configuration management
|
|
- Address OWASP Top 10 concerns
|
|
- Consider API security (rate limiting, CORS, etc.)
|
|
|
|
### Performance & Scalability
|
|
- Identify potential bottlenecks early
|
|
- Consider database query optimization needs
|
|
- Plan for caching strategies
|
|
- Assess resource usage (memory, CPU, network)
|
|
- Design for horizontal/vertical scaling
|
|
- Plan for load distribution
|
|
- Consider asynchronous processing where appropriate
|
|
|
|
### Edge Cases & Failure Modes
|
|
- Think through error scenarios
|
|
- Plan for network failures
|
|
- Consider partial failure handling
|
|
- Design retry and fallback mechanisms
|
|
- Plan for data consistency
|
|
- Consider race conditions
|
|
- Design for graceful degradation
|
|
|
|
### Architecture Design
|
|
- Create scalable system architectures
|
|
- Design for maintainability
|
|
- Plan component interactions
|
|
- Design data flow
|
|
- Consider microservices vs monolith trade-offs
|
|
- Plan API contracts
|
|
- Design state management
|
|
|
|
## Best Practices
|
|
|
|
- Document design decisions and rationale
|
|
- Consider both technical and business requirements
|
|
- Think through the entire user journey
|
|
- Plan for monitoring and observability
|
|
- Design with testing in mind
|
|
- Consider deployment and rollback strategies
