Auto Scaling
Auto Scaling is a management service that automatically adjusts elastic computing resources based on user business needs and policies.
Scaling Groups
A Scaling Group is a collection of cloud server instances that follow the same rules and target the same scenario. A scaling group defines the maximum and minimum number of CVM instances in the group, its associated load balancing instances and other attributes.
Launch Configuration
Launch Configuration is a template for automatically creating a CVM, which includes the image ID, CVM instance type, system disk and data disk type and capacity, key pair, security group, etc.
You must specify a launch configuration when you create a scaling group. Once a launch configuration is created, its attributes cannot be edited.
Alarm Scaling
Automatically increase or decrease CVM instances based on cloud monitoring metrics (such as CPU, memory, and network traffic).
Scheduled Action
A Scheduled Scaling Task is a type of auto scaling. When a fixed time point is reached, the CVM instance is automatically increased or decreased, and periodic repetition is supported.
Scaling Policy
Scaling Policy is the condition for executing scaling actions. The trigger condition can be a time or cloud monitoring alarm, and the action can be removing or adding CVM.
Scheduled Scaling Policy
When a fixed time point is reached, the CVM instance is automatically increased or decreased, and periodic repetition is supported.
Cooldown Period
The cooldown period refers to the lock time after a scaling activity is completed in the same scaling group.
