A Public Preview feature that automatically attaches custom tags to the serverless notebooks, jobs, pipelines and serving endpoints a user runs, letting their cost be traced in system.billing.usage and budgets. Classic compute isn't tagged by it.
Also called formerly serverless budget policy, Serverless budget policy.

Each book explains Serverless usage policy in context, with comparison tables and the common traps.
Terms in this definition
- Preview channel
The pipeline runtime channel for trying out new features and upcoming runtime changes. Production pipelines belong on
current. - Custom tags
Your own key-value labels, attached to compute, pools, SQL warehouses or whole workspaces. They appear in usage records and in Azure cost reports, which makes it possible to charge spending back, and a compute policy can insist on them.
- Serverless
Compute tier for single Azure SQL databases that scales automatically, pauses when idle and charges by the second. It is offered in General Purpose and Hyperscale, not Business Critical, and reserved capacity does not apply.
- Chat message roles
Labels on chat messages: instructions go under system, the person's input under user, the model's previous answers under assistant, and results returned by a called tool under tool (or function).
- Agents (classic) API
First-generation Foundry Agent Service API, based on threads, messages and runs. It is deprecated, replaced by conversations and responses, and retires on 31 March 2027.
- system.billing.usage
The system table to build cost queries on, covering billable usage for the whole account. Records usually appear within 12 hours.
- Budgets
In Cost Management, spending limits you can scope and filter by tag, which raise alerts when actual or forecast spend nears or passes them.
- Classic compute
All-purpose, jobs and pipeline compute running in your own Azure subscription, which you set up and manage yourself. Its counterpart is serverless compute, which Azure Databricks runs for you.
