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

Tutorial 01 — First workspace

Comparative positioning note

This document is written from the perspective of Microsoft Azure, Cloud Scale Analytics, and CSA Loom. Any description of third-party or competing products, services, pricing, or capabilities is derived from publicly available documentation and sources believed accurate at the time of writing, and is provided for general comparison only. We do not claim expertise in, or authority over, any non-Microsoft product or service; the respective vendor's official documentation is the authoritative source for their offerings, which may change over time. Nothing here is intended to disparage any vendor — where a competing product has genuine advantages, we aim to note them honestly. Verify all third-party details against the vendor's current official documentation before making decisions.

Create your first CSA Loom workspace via the Console. ~5 minutes.

How navigation actually works

Loom's left nav has top-level surfaces (Home, Workspaces, Browse, OneLake catalog, Unified catalog, Lineage, API marketplace, Governance, Monitor, Real-Time hub, Data agents, Copilot, Workload hub, Connections, Deployment, Admin portal, Setup wizard). A workspace is a container of items shown as a flat tree; you create items inside it with “+ New item”, and each opens its editor at /items/<type>/<id>. There is no per-workspace left-rail of service panes — pick the item type in the “+ New item” dialog.

Prerequisites

  • Loom deployed (see Quick Start)
  • You can create workspaces (member of the Loom admins Entra group)
  • Console URL open in your browser

Steps

1. Open Workspaces

Click Workspaces in the left nav. You'll see any existing workspaces as tiles/rows.

2. Create a workspace

Click + New workspace (top-right). The dialog captures:

  • Name: tutorial-demo
  • Description: My first CSA Loom workspace
  • Capacity: leave the default (Loom-native; no Fabric capacity required)
  • Domain: pick a domain or leave unassigned

Click Create. The workspace is a Cosmos-backed container that owns items — it's created immediately (no multi-minute resource provisioning; the Azure backends are already deployed by the DLZ and shared).

3. Open the workspace

Click the new workspace to open its item tree (empty to start) at /workspaces/<id>.

4. Add your first item

Click + New item, choose a type (e.g. Lakehouse, Notebook, Warehouse, KQL Database, Data agent…), name it, and Create. It opens in its editor at /items/<type>/<id>. Repeat to add more — they appear in the workspace tree.

5. (Optional) Delete the workspace

From the Workspaces list, use the workspace's row action to delete it (removes the Cosmos record + its items; the shared Azure backends remain).

Troubleshooting

If workspace creation fails: - Check Console "Monitoring → Deploy history" for the error - Most common: capacity quota exceeded — pick smaller SKU or request quota - See Deploy failure runbook
