Data isolation
Async processing
The constraint
Multi-tenancy is the decision you cannot defer. Isolation bolted on after a schema exists means every query becomes a place to forget a tenant filter. Building it in from the first table makes the boundary structural instead of a convention everyone has to remember.
Architecture
- TENANT ISOLATION
- Inventory, bookings and operations are isolated per tenant, so one customer's data and configuration cannot leak into another's.
- CONFIGURABLE RULES
- Business rules are tenant-specific by design rather than by branching — the same code path serves different operators.
- ASYNC AND SCHEDULED WORK
- Celery Beat and Workers handle booking reminders, inventory sync and background operations off the request path.
- STORAGE AND SEARCH
- MinIO for tenant document and file storage, Meilisearch for fast full-text resource discovery.
- DELIVERY
- Services containerised with Docker and orchestrated on Kubernetes, with Traefik handling reverse-proxy routing and load balancing.
- DATA LAYER
- PostgreSQL behind FastAPI services, with the schema shaped around tenant boundaries rather than bolted on afterwards.
