Target customers: users whose business load experiences peak and off-peak hours, and enterprise users who need to frequently adjust the number of instances. Features released: Auto Scaling now supports target tracking scaling rules. You do not need to manage scaling rules or configure alarm tasks. After you specify monitoring metrics, Auto Scaling will dynamically adjust the number of instances based on the specified monitoring metrics to meet your business needs. Benefits: 1. After you specify monitoring metrics and target values, you do not need to configure alarm tasks. 2. Auto Scaling dynamically calculates the number of instances that your business needs, without the need to trigger scaling rules frequently. 3. Target tracking scaling rules take into consideration the warm-up time for adding an instance. This helps Auto Scaling manage instances more precisely and avoid deleting too many instances.
