Elastic Compute Service:CreateElasticityAssurance

Last Updated:Sep 29, 2024

Creates an elasticity assurance in a region. When you call this operation, you can specify parameters, such as ZoneId and InstanceType, in the request.

Operation description

Elasticity Assurance provides a new way to purchase and use resources with flexibility and assurance. It offers assured resource reservations for pay-as-you-go Elastic Compute Service (ECS) instances. For more information, see Overview of Elasticity Assurance.

  • Elasticity assurances are not refundable after purchase.
  • Elasticity assurances are applicable to only pay-as-you-go ECS instances.
  • Elasticity assurances support only the unlimited mode. Therefore, you can set AssuranceTimes only to Unlimited. Elasticity assurances in unlimited mode can be applied an unlimited number of times within their effective period and take effect immediately after they are purchased.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
