About This Architecture

Multi-tenant SaaS architecture on Azure using Front Door WAF for global traffic routing, three App Service instances with staging slots for zero-downtime deployments, and private endpoints securing all data access. App Services authenticate via System-Assigned Managed Identities to Azure SQL Server elastic pools, Storage Account blob containers, and Key Vault secrets—all isolated within a single VNet using private DNS zones and NSGs. Application Insights and Log Analytics provide unified monitoring across all tenant workloads. This pattern demonstrates Azure best practices for isolation, compliance, and operational excellence in production SaaS environments. Fork this diagram on Diagrams.so to customize resource names, regions, or add additional App Services and storage tiers. Consider adding Azure API Management or Traffic Manager for advanced routing and failover scenarios.
