Hi Federico,

Great question, Azure billing meters vs. Databricks SKUs can be confusing because:

• Azure exposes meters (what you get invoiced for),

• Databricks exposes SKUs (logical product categories),

• And system.billing surfaces SKU usage, not Azure meter names.

Premium Jobs Compute DBU

Billed for classic jobs clusters running non-Photon workloads.

Premium Jobs Compute Photon DBU

Same as above but when the job cluster uses Photon.

 Premium Serverless SQL DBU

DBUs consumed by Serverless SQL Warehouses.

Premium All-Purpose Compute DBU

DBUs consumed by interactive / all-purpose clusters (not using Photon).

 Premium All-Purpose Photon DBU

Same as above but when the cluster uses Photon.

🔸 Premium Automated Serverless Compute DBU

This is for Serverless Jobs Compute — the serverless replacement for classic jobs clusters.

Used when:

• You run a Job with Jobs Compute = Serverless

• No cluster provisioning — Databricks runs the compute in its serverless pool

Equivalent Databricks SKU:
➡ PREMIUM_JOBS_SERVERLESS_COMPUTE_<region>

Premium Interactive Serverless Compute DBU

This is for Serverless All-Purpose Compute (in Public Preview in some regions).

Used when:

• You create a Serverless All-Purpose Workspace cluster

• Interactive notebook sessions run in serverless mode

• Photon is on by default

Equivalent Databricks SKU:
➡ PREMIUM_ALL_PURPOSE_SERVERLESS_COMPUTE_<region>

Below is the clean 1:1 mapping:
