Apply DSC sequentially in Availability Groups and Zones
Say you have a configuration that applies to two servers behind a load balancer and it includes the installation of some software.
You now want to upgrade that software so you update the product ID and link to MSI.
Once the servers pick up the change and attempt to apply it, they could both do it simultaneously causing a system outage.
Having DSC respect Availability Groups and Zones would prevent this happening and allow the use of DSC for automatic upgrades.
This scenario is already addressed by Azure DevOps environments, however we have not done our part to make sure it is easy to understand how to integrate the two services. We will address this in our documentation.
