RDS provides whitelist access policies. You can set permitted IP addresses and IP network segments to effectively prevent hackers from attacking the server by port scanning.
A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group. They set the "Minimum
number of instances" to 6 and the "Maximum number of instances" to 8. After correctly configuring scaling
settings, the customer adds a scaling rule “Adjust to 10 ECS instances” and creates a scheduled task based on
this rule. Then, the customer checks the scaling group and sees it already contains 6 valid ECS instances.
They then enable this scaling group immediately. How many ECS instances will be in the scaling group when
the scheduled task is activated once?

In Auto Scaling, a scaling group refers to the collection of ECS instances deployed with the same
applications, where these ECS instances can be charged by monthly subscription or Pay-As-You-Go. For
scenarios with abrupt service traffic change, Pay-As-You-Go ECS instances can meet service requirements
while minimizing cost. For monthly subscription ECS instances, you can manually add the idle instances to
the scaling group to take full advantage of idle resources.
