Hi Mark, couple of clarifications:
- This does not impact the VMSS with Bronze durability at all. The VM Count requirement is not changing for durability Bronze.
- This is only applicable to the VMSS with Silver & Gold durability.
- Initially, we will only enforce these on the new clusters created post 10/30 and gradually we will enable these checks on all clusters
- When enabled for all existing clusters, these checks will prevent VMSS update operations (like Scale-in, Reimage operations etc..), if the VMSS is found to be misconfigured. It will not impact application updates.
- We want customers to understand that these misconfigurations, even though the requirements were publicly documented since the beginning but never enforced until now, should be avoided as they can result in unreliability or even availability losses.
