Azure Automation Desired State Configuration (DSC) builds on Windows PowerShell DSC to provide an easier configuration management experience. Automation DSC allows you to author and manage PowerShell DSCs, import DSC resources, and generate DSC node configurations—all in the cloud.
These DSC items are placed on the Automation DSC pull server so that target nodes (such as physical and virtual machines) in the cloud or on-premises can pick them up, automatically conform to the desired state, and report back to Automation about compliance with the desired state.
Now in public preview, Automation DSC is available in the Free and Basic tiers. Automation DSC will be included in the Microsoft Operations Management Suite
add-on when the service becomes generally available. For more information, please visit the Azure Automation DSC Overview
