What problem were we solving?
Each new customer required dedicated infrastructure provisioning, increasing costs linearly and slowing onboarding from days to weeks.
Key Constraints
Per-customer data isolation required for compliance
Cannot disrupt existing 50+ customers during migration
Performance must remain consistent as tenant count grows
Team needed training on multi-tenant patterns
What paths were on the table?
Silo model (separate database per tenant)
Pool model (shared database, row-level security)
Bridge model (shared infrastructure, isolated schemas)
Keep current single-tenant and optimize per-tenant
The Decision
Implemented a bridge model — shared compute infrastructure with schema-level isolation per tenant. This balanced cost efficiency with data isolation requirements.
Measurable business outcomes
Per-customer infrastructure cost dropped 70%. New customer onboarding went from 2 weeks to 4 hours. Platform supported 3x more tenants with the same infrastructure team.
