How it works
A straightforward architecture that lives in your Azure.
Nublou uses Azure-native building blocks-managed apps, Functions, Static Web Apps, Key Vault, and Cosmos DB-to ingest cloud billing data, apply allocation rules, and publish Cloud P&L views, all inside your tenant.
High-level architecture
Data sources (Azure, AWS, GCP) flow into a tenant-deployed ingestion and normalization layer, then into a rules and allocation engine. Curated datasets are published for Power BI, Excel, and APIs.

Security touchpoints
- • Authentication via Microsoft Entra ID (no local passwords).
- • Authorization enforced at route and API layers.
- • Secrets stored in your Azure Key Vault with RBAC and managed identities.
- • Data encrypted at rest (AES-256) and in transit (TLS 1.2+).
- • Tenant isolation via a dedicated managed app instance per customer.
