CSA Loom — the Microsoft Fabric experience for Azure tenants where Fabric isn't yet available: lakehouses, warehouses, notebooks, semantic models, Activator rules, Data Agents, across Commercial, GCC, GCC-High, and DoD IL5

For Azure Commercial

The baseline deployment. Full feature set; UC managed catalog; Foundry Agent Service; Container Apps everywhere. Semantic models + reports run on the Azure-native tabular layer (Azure Analysis Services) by default — no Power BI Premium is required; Power BI is strictly opt-in for Direct Lake parity (see below).

Prerequisites

Item Notes
Azure Commercial subscription Not GCC tenant (Azure Commercial under M365 GCC)
Region Any Azure Commercial region with Databricks Premium + ADX + AOAI quota (recommended: eastus2, westus2, eastus, westeurope)
Quota for Databricks Premium workspace az vm list-usage --location eastus2
Quota for ADX cluster (D14_v2 min recommended)
Quota for AOAI (gpt-4o + text-embedding-3-large) 50K TPM minimum
Compliance tags Customer-supplied (CostCenter, Owner, etc.)

Optional — only with LOOM_SEMANTIC_MODEL_BACKEND=powerbi. A Power BI Premium F-SKU capacity (F8 minimum for production) is required only if you opt into the Power BI / Direct-Lake-Shim backend for sub-30-second semantic-model freshness. On the default Azure-native path (Azure Analysis Services), no Power BI Premium capacity is provisioned or billed.

Deploy

Use commercial.bicepparam:

az deployment sub create \
  --name csa-loom-commercial-$(date +%s) \
  --location eastus2 \
  --template-file platform/fiab/bicep/main.bicep \
  --parameters platform/fiab/bicep/params/commercial.bicepparam \
  --parameters adminEntraGroupId=<group-guid>

What's deployed differently from Gov

Component Commercial Gov delta
Container host Azure Container Apps (Gov uses AKS at IL4+)
Catalog primary Databricks Unity Catalog managed (Gov-IL4 uses Purview; IL5 uses Atlas-on-AKS)
SQL Warehouse Databricks SQL Warehouse (Gov uses Synapse Serverless)
Agent orchestration Foundry Agent Service (Gov uses MAF + AOAI direct)
APIM Premium v2 (Gov uses classic Premium)
Functions host Flex Consumption (Gov uses Premium EP1)
OpenAI models Full catalog (Gov restricted to gpt-4o, gpt-4.1, o3-mini, gpt-5.1)
Direct Lake parity Full warm-cache materializer; native Direct Lake when forward-migrating to Fabric (same warm-cache; native Direct Lake not yet in Gov)
Defender for Cloud AI Threat Protection ✅ enabled (Gov: manual Sentinel pipeline)

Validation

After deploy:

# Console URL from azd output
curl -i https://<your-console-url>/api/health
# Expected: {"status":"healthy"}

Then sign in via browser, verify: - Workspaces pane shows the auto-created default-workspace - Catalog shows the canary dataset - Monitoring Hub health green across all pillars

Cost (Azure-native Commercial baseline)

Component Approximate $/month
Databricks Premium (1 workspace, 10-50 DBU/day) $500-2,500
Synapse Serverless (light usage) $5-50
ADX cluster (D14_v2 base) $500
ADLS Gen2 (10 TB) $200
AOAI (50K TPM gpt-4o) $200-500
AI Search (S1) $250
Purview (1 vCore) $300
Container Apps Env + workloads $50-200
AI Foundry Hub $0 base + AOAI consumption
Misc (KV, LA, App Insights) $50
Total ~$2,050-4,550/mo

Optional add-on — only with LOOM_SEMANTIC_MODEL_BACKEND=powerbi: a Power BI Premium F8 capacity for the Direct-Lake-Shim path adds ~$1,049/mo. This is not part of the Azure-native baseline above — the default Azure Analysis Services tabular layer carries no separate capacity charge.

CSA Loom IP itself is free in v1.
