Think of min and max as the maximum allowed brightness on a screen. You probably don't want to min to be 0 in that case (sidenote). The desired quantity keeps changing based on the env (in the case of ASG, it depends on the scaling policies). For instance, if the following check runs every hour, this is where desired quantity is required.

So manually scaling up and down will result in your ASG restoring the number of instances to the Desired Capacity. If you want to manually scale up and down, you could set your Max and Min to a wide value, and move Desired Capacity within it. So you could do Max=10, Min=1, Desired=3.

2015年5月28日 · So I created an ASG and set it to: max_size = 1 min_size=0 desired_capacity = 0 Next I created a warm pool with the following: Warm pool instance state = stopped Max warm pool size = 1 Max prepared capacity = 'Equal to ASG max …

Use SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1 use SES to send emails to customers. D.

2023年10月26日 · And then there is an auto-scaling group based on the SQS depth (using the formula number of messages / number of instances) with a cap of 5 instances (so never more that 5 instances running in ASG). I created the auto-scaling policy for that and read that this type of policy can trigger itself and doesn't need an alarm (?).

2019年7月23日 · I am trying to stop and start EC2 instances mapped with ASG on a particular timeframe. I am getting access denied errors even after giving the role appropriate permissions. resource "

2020年7月24日 · We have asg with current policy. example current date time UTC : 23 May 2020 , 0600 AM and i have policy to stop and start instance at cron time 1000 AM but when i m applying now terraform plan , at aws we can see policy start …

2021年3月10日 · For cost reasons, our ASG's in the QA environment run with desired/min/max capacity set to "1". That's not the case for Production but since we use the same code for QA and Prod deployment (minus a few variables of course) this is causing problems with the QA automation jobs.

2020年10月13日 · I am planning to build an auto-scaling group (ASG) in a multi-AZ (AZ = availability zone) network. Let's say that we ran some diagnostics and discovered that we need at least 8 instances for normal load, and 24 instances during peak times.
