Desired State Configuration: Managed Object Format Files

Jess Pomfret explains what Managed Object Format (MOF) files are and why they’re useful for Desired State Configuration:

When I run this script I see the output in the screenshot below, a MOF file has been created in my output folder. Managed Object Format (MOF) files are used to describe Common Information Model (CIM) classes, these are industry standards which gives us flexibility in working with DSC. In DSC this is important as the MOF file is the artefact that will actually be used to configure our nodes. This MOF will be delivered to our target node and enacted by the Local Configuration Manager (LCM).

The LCM will be covered in more detail in a later post, but for now know that it can be configured to be in either ‘Push’ mode or ‘Pull’ mode.  Pull mode is more complicated to set up but perhaps more appropriate for managing a large number of servers.  For now, we will look at the ‘Push’ mode where we will deliver the MOF manually to the target node for the LCM to enact.

There are a lot of TLAs to watch out for within Desired State Configuration.
