Source: Pattern·Target: Failure Mode

Summary

Tenant isolation partitions resources between tenants so that one tenant's workload cannot consume resources allocated to others, eliminating the noisy neighbor problem.

Evidence

·tenant_noisy_neighbor lists tenant_isolation in affects_patterns; mitigation isolates high-volume tenants to dedicated infrastructure (failure_modes/tenant_noisy_neighbor.yaml)
·tenant_isolation describes the exact contention (buffer-cache eviction, WAL saturation, connection exhaustion) and reduces blast radius (patterns/tenant_isolation.yaml)

Evidence grounding

Grounded, 2 supporting items

Tiered isolation (shared for most tenants, dedicated for power users) bounds a noisy tenant's blast radius.
