Multi-tenant SaaS request flow on Azure routes customer requests through Front Door and Application Gateway to App Service, which resolves tenant identity via Tenant Resolution Service. App Service queries Tenant Metadata Database to retrieve tenant-specific connection strings, retrieves secured credentials from Azure Key Vault, and accesses the tenant's dedicated Azure SQL Database. Azure Monitor and Application Insights collect observability data across all layers, enabling comprehensive logging and performance tracking. Fork this diagram to customize tenant isolation strategies, add caching layers, or integrate additional Azure services like Cosmos DB or Service Bus. The architecture demonstrates Azure best practices for secure, scalable multi-tenant isolation with centralized secret management and unified monitoring.
