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

From "Deploy to Azure" button

The portal-click deployment path. Best for evaluators who prefer the Azure portal over CLI.

How to use

  1. Open the csa-inabox README
  2. Click the Deploy to Azure button under the CSA Loom section
  3. Azure portal opens with the pre-rendered ARM template
  4. Fill in the form (same parameters as azd up):
  5. Subscription
  6. Region
  7. Boundary (Commercial / GCC / GCC-High)
  8. Deployment mode (single-sub / multi-sub)
  9. Capacity SKU
  10. Admin Entra group object ID
  11. Hub VNet CIDR
  12. Click Review + create
  13. Wait ~35-55 minutes for Admin Plane + ~15-40 min for first DLZ

Behind the scenes

The Deploy to Azure button uses a special URL format that loads a GitHub-hosted ARM template into Azure portal's deployment UI:

https://portal.azure.com/#create/Microsoft.Template/uri/<URL-encoded ARM template URL>

The ARM template is mainTemplate.json — compiled from platform/fiab/bicep/main.bicep via az bicep build. Re-rendered per release and published to a public GitHub Pages URL.

Per-boundary variants

The README shows three Deploy to Azure buttons:

Button Pre-set boundary
Deploy to Azure Commercial Commercial
Deploy to Azure (GCC pair) GCC
Deploy to Azure Government GCC-High

Each links to a separately-rendered ARM template with the boundary parameter pre-filled. The portal still lets the customer override.

Limitations vs azd up

Capability Deploy button azd up
One-click portal install ✅ ❌
Per-env reproducibility ❌ (manual re-fill) ✅
Bicep visibility ❌ (ARM template only) ✅
Custom Bicep modules ❌ ✅
CI/CD integration ❌ ✅
Best for Evaluators Production / platform engineers

Federal customers

For GCC-High / IL5, the Azure Government portal is at portal.azure.us (not portal.azure.com). The Deploy to Azure URL format is slightly different for Gov:

https://portal.azure.us/#create/Microsoft.Template/uri/<URL-encoded ARM template URL>

Loom's Gov Deploy-to-Azure button uses this format.

After deploy

Same as azd up — Loom Console comes up at the output URL; sign in with your Entra identity; create your first workspace via Tutorial 01.

Tear down

Delete the resource groups from the Azure portal (search for "fiab-*" in your sub). Or:

az group list --query "[?starts_with(name, 'fiab-')].name" -o tsv | \
  xargs -I {} az group delete --name {} --yes --no-wait
