A multi-tenant SaaS platform must balance cost efficiency (shared infrastructure) with security (tenant isolation). This Azure-native architecture uses Azure AD B2C for identity with tenant-scoped JWTs, row-level security in Azure SQL for data isolation, Redis Cache for instant feature flag lookups, and Azure Functions for asynchronous usage metering that feeds billing integration. Ideal for SaaS founders building multi-tenant platforms that need per-tenant isolation, usage metering, and subscription billing.
