Auto Scaling (AS)

Auto Scaling (AS) automatically adjusts computing resources based on the user service requirements and configured policies. The number of instances changes along with service traffic, ensuring the stable running of services.

Free Trial Use

Automatic and Flexible

Automatically adjusts the number of instances based on scheduled, periodic, or alarm-triggered AS policies and binds new instances to load balancing listeners.

High Availability

Automatically checks the instance status in AS groups and replaces unhealthy ones to ensure proper service running.

Visualized Management

Provides a visual display for overall monitoring and intuitively displays monitoring graphs for each AS group, helping users predict service changes and manage O&M.

Low Cost

Users are charged only for the ECS resources that they used.

Application Scenarios

  • Data Processing & Computing Applications

Data Processing & Computing Applications

AS uses ECSs to process content, automatically scales in or scales out resources, and uses OBS to transmit data online.

Advantages

  • Flexible

    Supports scheduled, periodic, and alarm-triggered AS policies.

  • Low Cost

    Users are charged only for the ECS resources that they used.

  • Load Balancing

    Automatically binds new ECSs to load balancing listeners.

Function Description

Auto Scaling

Automatically adjusts computing resources to ensure the stable running of services.

  • Dynamical Scaling

    Dynamically adjusts the number of instances in an AS group based on monitoring data and application running statuses.

  • Scheduled or Periodic Scaling

    Automatically increases or decreases the number of instances in an AS group periodically or at configured intervals.

Automatic Load Balancing

Automatically binds new instances to load balancing listeners.

Auto Instance Adjustment

Automatically replaces unhealthy instances to ensure service availability.

Auto Notification

Allows users to receive a notification when their AS group changes so that they can promptly know the running status of the AS group.
