Multi-tenant systems host many customers on common infrastructure, separating data through access controls, database partitioning, and encryption. It is the standard model for software as a service.
Isolation quality determines whether separation is effective.
Alternative Names:
Multitenancy, Shared Infrastructure
Why it Matters?
Multi-tenancy is not inherently less secure, and properly implemented isolation satisfies most requirements at substantially lower cost than dedicated infrastructure. The diligence question is whether isolation extends to every layer including search indexes, analytics, backups, and any AI retrieval, since separation at the document store alone leaves derived artifacts potentially crossing tenant boundaries.
