Creates an auto provisioning group.

Description

  • Auto Provisioning is a service that allows quick deployment of an instance cluster that consists of preemptible and pay-as-you-go instances. Auto Provisioning supports one-click deployment of instance clusters across different billing methods, instance families, and zones. For more information, see Use auto provisioning group-related API operations to create multiple ECS instances at the same time.
  • Auto Provisioning uses auto provisioning groups to schedule and maintain computing resources. You can use auto provisioning groups to obtain a steady supply of computing resources. This helps reduce the impact on computing capacity when preemptible instances are reclaimed.
  • Auto Provisioning is provided free of charge. However, you are charged for instance resources that are created in auto provisioning groups. For more information about the billing, see Overview and Pay-as-you-go.
  • When you specify both the LaunchTemplateId and LaunchConfiguration.* parameters, the LaunchTemplateId parameter takes precedence.
