Application Scenarios of ECSs

With the descriptions of the typical scenarios, you can learn how to use native OpenStack APIs to manage the life cycle of Elastic Cloud Servers (ECSs) and how to invoke the key interfaces.


Invoke native OpenStack APIs to manage the life cycle of ECSs, such as creating an ECS and deleting an ECS.


Due to system service capability limitations, pay attention to the following constraints when invoking native OpenStack APIs:

  • Do not use unsupported parameters when invoking APIs.
  • Invoke APIs by following the invoking sequence specified in the system. Do not change their invoking sequence.
  • ECSs may be unavailable if APIs are not invoked in accordance with this development guide. In this case, delete the instances and perform operations according to this document again.
