Operation Orchestration Service (OOS) allows you to execute a public or custom template in multiple execution modes.

Execution modes

  • Automatic: We recommend that you execute a template in this mode in the test environment first. In this way, you can have a better understanding of the O&M operations performed by the template. If the test result meets the expectations, you can execute the template in this mode in the production environment.
    • Automatic execution: All tasks defined in the template are automatically executed in sequence.
    • Execution that requires risk confirmation: Assume that you have specified irrevocable tasks, such as the delete, release, and stop tasks, in a template. When such a task is executed, the execution status of the template changes to Waiting until you approve the task.
  • Manual: This execution mode is similar to debugging. If you want to learn more about the execution of each task, we recommend that you use the manual execution mode.

Risk confirmation modes

  • Require confirmation for high-risk tasks: For irrevocable O&M operations, such as deleting an ECS instance, you need to confirm the operations. We recommend that you give priority to this option when executing a new template.
  • Skip confirmation for high-risk tasks: If you are familiar with all the tasks orchestrated by the template, you can select this option to skip the confirmation.
