Multi-Tenant Architecture: Pool, Silo, or Hybrid
The three canonical models, what they cost to operate, and the one decision you have to make early.

Multi-tenancy is a decision you make once and live with for years. The three canonical models — pooled (shared everything), siloed (one stack per tenant), and hybrid (shared compute, isolated data) — each have radically different operational profiles, security postures, and enterprise-sales implications.
Pooled is cheapest to run and hardest to sell to security-conscious enterprises. Siloed is the inverse. Hybrid is the answer most modern enterprise software development teams converge on, and it requires more discipline than either pure model to get right.
