I am using my own Azure VM scale set as the agent pool in Azure DevOps. The VM scale set consists of 3 nodes. However, when I run multiple jobs at the same time, only one agent is scheduling the jobs and the others are idle.
Does anyone know the difference between using your own VM scale set for the agent pools and running parallel jobs using parallel jobs?
Even though VM scale sets are used (which are less costly) do we need to still purchase parallel jobs ($40 per agent)?
