Azure-docs: When there's 2 apps on the same consumption plan...
Will the scale controller ever run functions from both apps on the same node?
Based on this page it doesn't look like it. Please confirm.

@ishepherd Thanks for the question! We are investigating and will update you shortly.

@ishepherd are you referring to running two different functions on one service plan or multiple instances of the same functions in the same app service plan? Such as when scaling out

Thanks - scenario is: I have one Consumption Plan and two Function Apps, both are installed on that one Plan. (All setup by ARM template).
Is it possible the 2 apps will run in the same functions host process?
Is it possible the 2 apps will run on the same compute node?

@ggailey777 could you chime in on this?

@ishepherd In the consumption plan the scaling is per-app. Contrary to the dedicated ASP the consumption ASP is just a grouping concept and it does not affect the scaling or isolation of the function apps within it. So that being said, having multiple functions within the same consumption plan should not put the functions on the same host node.
There is always a very small chance that things could be put on the same node depending on the availability of resources in the data center. However it would be a rare occurrence. Does that help?

Thanks for adding that extra information to the doc @ggailey777!
@ishepherd I will close this for now. We added additional information to the doc to make it more clear.
