> This article applies to dedicated SQL pools created in Azure Synapse Workspaces and not dedicated SQL pools (formerly SQL DW). There are different PowerShell cmdlets to use for each, for example, use `Suspend-AzSqlDatabase` for a dedicated SQL pool (formerly SQL DW), but `Suspend-AzSynapseSqlPool` for a dedicated SQL pool in an Azure Synapse Workspace. For more on the differences between dedicated SQL pool (formerly SQL DW) and dedicated SQL pools in Azure Synapse Workspaces, read [What's the difference between Azure Synapse (formerly SQL DW) and Azure Synapse Analytics Workspace](https://techcommunity.microsoft.com/t5/azure-synapse-analytics-blog/what-s-the-difference-between-azure-synapse-formerly-sql-dw-and/ba-p/3597772).

## Pause compute

To reduce costs, you can pause and resume compute resources on-demand. For example, if you won't be using the database during the night and on weekends, you can pause it during those times, and resume it during the day.
