Auto Scaling

Auto Scaling (AS) automatically adjusts computing resources based on service requirements and configured policies to ensure stability and optimize costs.

Free of Charge

Auto Instance Adjustment

Dynamic adjustments based on scheduled, periodic, or alarm-triggered AS policies automatically create and bind new instances to load balancing listeners.

High Availability

Automatic instance status checks in AS groups with immediate replacement of faulty instances ensure service availability.

Visual Management

Visual management intuitively displays monitoring graphs for each AS group for easier O&M and service change prediction.

Low Cost

Pay-per-use model for ECS resources offers cost effectiveness and flexibility.

Application Scenarios

  • Data Processing & Computing

Data Processing & Computing

Data Processing & Computing

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

    Usage-based charging ensures optimized costs and charging only for the ECS resources that were used.

  • Load Balancing

    Automatically binds new instances to load balancing listeners.
