Covers Auto Scaling groups, launch configurations, scaling policies (target tracking, step, simple), lifecycle hooks, scheduled actions, instance refresh, warm pools, load balancer integration, notifications, metrics collection, and tag management.

Quick Reference — Common Workflows

Create an Auto Scaling group

aws autoscaling create-auto-scaling-group --auto-scaling-group-name my-asg \
  --launch-template LaunchTemplateId=lt-0123456789abcdef0,Version='$Latest' \
  --min-size 1 --max-size 4 --desired-capacity 2 \
  --vpc-zone-identifier "subnet-abc123,subnet-def456" \
  --tags Key=Environment,Value=prod,PropagateAtLaunch=true

Update desired capacity

aws autoscaling set-desired-capacity --auto-scaling-group-name my-asg \
  --desired-capacity 3

Create a target tracking scaling policy

aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg \
  --policy-name cpu-target-70 --policy-type TargetTrackingScaling \
  --target-tracking-configuration file://target-tracking.json

Create a scheduled action

aws autoscaling put-scheduled-update-group-action \
  --auto-scaling-group-name my-asg \
  --scheduled-action-name scale-up-morning \
  --recurrence "0 8 * * MON-FRI" \
  --min-size 4 --max-size 10 --desired-capacity 6

Start an instance refresh (rolling update)

aws autoscaling start-instance-refresh --auto-scaling-group-name my-asg \
  --preferences MinHealthyPercentage=90,InstanceWarmup=300

Create a lifecycle hook

aws autoscaling put-lifecycle-hook --auto-scaling-group-name my-asg \
  --lifecycle-hook-name launch-hook \
  --lifecycle-transition autoscaling:EC2_INSTANCE_LAUNCHING \
  --heartbeat-timeout 300 --default-result CONTINUE

Create a warm pool

aws autoscaling put-warm-pool --auto-scaling-group-name my-asg \
  --pool-state Stopped --min-size 2

Attach/detach instances

aws autoscaling attach-instances --auto-scaling-group-name my-asg \
  --instance-ids i-0123456789abcdef0
aws autoscaling detach-instances --auto-scaling-group-name my-asg \
  --instance-ids i-0123456789abcdef0 --should-decrement-desired-capacity
