Multi-tenant SaaS request flow on Azure routes customer requests through Front Door and Application Gateway to App Service, with tenant resolution determining data access paths. The Tenant Resolution Service queries Tenant Metadata Database and retrieves secrets from Key Vault and App Configuration to establish tenant context. App Service accesses tenant-isolated Azure SQL Database instances while Azure Monitor and Application Insights capture telemetry throughout the request lifecycle. This architecture demonstrates Azure's native multi-tenancy patterns, enabling secure tenant isolation, dynamic configuration, and comprehensive observability.
