Production Patterns Lab

The Production Patterns Lab covers the decisions that appear across many systems, even when the products are very different.

Pattern Areas

• authentication and authorization
• sessions and JWT
• RBAC and ABAC
• idempotency
• optimistic and pessimistic locking
• distributed locks
• retries and backoff
• cache strategies
• queues and dead-letter handling
• feature flags and audit logs

What This Lab Should Emphasize

• problem statement first
• multiple approaches
• context-specific tradeoffs
• edge cases and failure behavior
• implementation notes that are realistic enough to build from
