Which service for autoscaling automation

0

Hi,

I am looking to increase the minimum nodes in one AZ by updating the autoscaling group and decrease the minimum nodes to zero on other AZ.

Which service (step function ,lambda..) will seamlessly perform these two steps in AWS

Hello.

Why would you want to increase capacity only in a specific AZ?
Can't you solve this by specifying only a specific subnet from the beginning without using Lambda etc.?

+1 to Riku's questions, what's the usecase here? There might be better solutions for your underlying problem

But to answer your question, it depends on exactly what you're doing. You can't set min/max/desired on the ASG per AZ. If you're trying to shift all traffic from one AZ to another, then you could use a Lambda to change the subnets in the ASG, so that you remove the current subnet in AZ1, and add a replacement subnet in AZ2. The ASG will the automatically rebalance the instance into the new AZ
