//! Admin Workflow Example: System Management and Monitoring
//!
//! In the simplified model where buckets are auto-created when users create drives,
//! the admin role shifts from manual infrastructure setup to:
//! - Managing provider availability
//! - Setting system policies
//! - Monitoring system health
//! - Handling failures
//!
//! Bucket creation happens automatically when users create drives via Layer 1.
