Elastic Compute Service:Overview

Last Updated:Oct 31, 2023

CloudOps Orchestration Service (OOS) automatically manages and executes O&M tasks. You can define items, such as O&M tasks, execution processes, and inputs and outputs of executions, in templates and then execute the templates to automate O&M.


The following table describes the scenarios for which OOS is suitable.



Scheduled and batch O&M tasks

To check the available storage space of cloud disks on multiple ECS instances at the same time, you can use OOS to select the ECS instances by instance name, tag group, or resource group and then run Cloud Assistant commands to check the cloud disks and view all check results at once.

Event-driven O&M tasks

When the vCPU utilization of an ECS instance reaches 85%, you can use OOS to automatically restart the instance to prevent service interruptions.

Cross-region O&M tasks

You can copy multiple ECS instances from one region to another by using the image copy feature.

O&M tasks subject to approval

You can add an approval process for purchasing or releasing ECS instances.

OOS is a platform that standardizes O&M tasks. You can create templates from manuals, such as Operations and Maintenance Guides, User Guide, and Operation Guides, to perform operations as code.


OOS improves the efficiency and security of O&M tasks by offering the following benefits:

  • Visualized execution processes and results

  • Free and managed service

  • Efficiency in batch managing multiple O&M tasks

  • Superior authentication and verification systems

  • Easy-to-use templates

  • Cross-region O&M

  • Operations as code

  • Delegated authorization
