## Key Concepts
### Infrastructure as Code (IaC)
The provisioning platform uses **declarative configuration** to manage infrastructure. Instead of manually creating resources, you define what you want in Nickel configuration files, and the system makes it happen.
### Mode-Based Architecture
The system supports four operational modes:
- **Solo**: Single developer local development
- **Multi-user**: Team collaboration with shared services
- **CI/CD**: Automated pipeline execution
- **Enterprise**: Production deployment with strict compliance
### Extension System
Extensibility through:
- **Providers**: Cloud platform integrations (AWS, UpCloud, Local)
- **Task Services**: Infrastructure components (Kubernetes, databases, etc.)
- **Clusters**: Complete deployment configurations
### OCI-Native Distribution
Extensions and packages distributed as OCI artifacts, enabling:
- Industry-standard packaging
- Efficient caching and bandwidth
- Version pinning and rollback
- Air-gapped deployments
