Complete the steps in this topic to create a simple scaling solution.

Procedure

  1. Log on to the Auto Scaling console, then choose Overall solution creation and management from the navigation pane.

  2. Create a scaling group. A scaling group is made up of ECS instances that can be used in the same scenario. You can define the minimum and maximum number of ECS instances in the group, and the associated Server Load Balancer instances and RDS instances.

    1. Configure the parameters listed.
      Note For Minimum Number of Instances Allowed for Scaling, Auto Scaling will create this number of ECS instances in the scaling group when you have created the scaling group. For Server Load Balancer, all the ports that the specified SLB is listening to must have health checks enabled.
    2. Click Submit.

    3. Click Create scaling configuration.

  3. Create a scaling configuration. You can configure the specifications of the ECS instances used for scaling.

    1. Enter a value or make a selection for each option listed. For Image Type, select Custom Image.

    2. Click Preview. The Preview page shows the configurations you selected and the cost of the solution.
      Note You are only charged for running ECS instances. Auto Scaling service is free.
  4. Click Complete. Check whether the scaling group you specified is created.

    Note Auto Scaling starts by creating the minimum number of instances you specify, and then adds these instances to the SLB service. The IP addresses of these instances are added to the RDS whitelist.
