Features
- scaling policies(Manual Dynamic Predictive Scheduled)
- health check replacements
Scaling policies
If an instance becomes unhealthy,
the group terminates the unhealthy instance and launches another instance to replace it.
Health check replacements
When the scaling policy is in effect, the Auto Scaling group adjusts the desired capacity of the group,
between the minimum and maximum capacity values that you specify, and launches or terminates the instances as needed.
Launch template
* 將會取締 "Launch Configurations"
* support versioning
To create a launch template
EC2 console > On the navigation pane, under INSTANCES > choose Launch Templates.
Auto-assign Public IP
Auto Scaling > Launch configurations 內設定
由於沒有 "Edit", 所以要 "Copy" 成新 config 才修改到,
過程中展開 "Advanced details" 再修改 Public IP address type
