Applied Architecture Lab

Applied labs connect multiple concepts into product-shaped systems.

First Scenario Families

• booking systems
• chat systems
• payment flows
• notifications pipelines
• file upload and processing
• e-commerce paths

What Makes These Labs Valuable

They expose the difference between:

• a concept in isolation
• and a concept inside a real product with constraints, concurrency, failure, and growth

Standard Questions

• what constraints matter here
• what is correctness-sensitive
• what is eventually consistent
• what is the user-facing failure mode
• how would the architecture evolve at higher scale
