Hello jshurak,
Good day!
Thank you once again for posting here.
To clarify, the “minimum instance count of 2” mentioned in the explanation refers to the “Minimum number of VMs: 2” specified in the scenario and NOT the “Initial instance count: 3” (as seen in the provided images).
Here’s a detailed breakdown of the scenario:
Scenario 2: Initial state: 3 VMs First condition: 70% CPU for 8 minutes (no action taken as duration is less than 10 minutes) Second condition: 15% CPU for 12 minutes Scale In Policy: If CPU < 20%, decrease by 2 VMs
In this scenario, the scale-in condition is met (CPU < 20% for more than 10 minutes). Therefore, 2 VMs will be removed from the initial 3 VMs. However, the minimum number of VMs is set to 2, so the scale set cannot go below this number.
Result: 3 (initial) – 1 (scaled in, limited by minimum) = 2 VMs
I hope this clears up any confusion. We appreciate your feedback, as it helps us improve our content and explanations.
Best regards,
Neil @ Tutorials Dojo
