AS Group

An AS group consists of a collection of instances that apply to the same scenario. It is the basis for enabling or disabling AS policies and performing scaling actions.

AS group involves the following terms:

  • Instance: an Elastic Cloud Server (ECS) in an AS group
  • AS policy: specifies a condition for triggering a scaling action.
    AS supports the following policies:
    • Alarm

      AS automatically increases or decreases the number of instances or sets the number of instances to the configured value when Cloud Eye generates an alarm for a configured metric, such as CPU Usage.

    • Scheduled

      AS automatically increases or decreases the number of instances or sets the number of instances to the configured value at a specified time.

    • Periodic

      AS automatically increases or decreases the number of instances or sets the number of instances to the configured value at a configured interval, such as daily, weekly, or monthly.
