CloudOps Orchestration Service (OOS) is an automated O&M service provided by Alibaba Cloud that helps you manage and run O&M tasks in the cloud. You can create templates to define execution tasks, the sequence of the tasks, input parameters, and output parameters, and use the templates to automatically run O&M tasks. This topic describes how to use OOS to manage Elastic Compute Service (ECS).
Scenarios
The following table describes the scenarios for which OOS is suitable.
Scenario | Description |
Run event-driven O&M tasks | You can use OOS to trigger an O&M action when an event occurs. This way, O&M tasks can be automatically and efficiently run without the need for human intervention. For example, you can use OOS to trigger instance restart when a high vCPU utilization event occurs. When the vCPU utilization of an ECS instance reaches 85%, the instance is automatically restarted. |
Run batch O&M tasks | You can use OOS to run O&M commands on multiple objects, such as ECS instances, at a time to perform regular operations and maintain the normal operation and health of your business. For example, to check the available space of disks on multiple ECS instances, perform the following steps: Search for ECS instances by instance name, tag, or resource group, run a Cloud Assistant command to check the available space of disks on the instances, and then view the check result. |
Run O&M tasks subject to approval | In many scenarios, you must add an approval process to ensure that only secure and expected O&M operations are performed. You can define an ACS::Approve action in a template to ensure that O&M tasks can be run only with manual approval and that only expected O&M tasks are run without mistakes. |
Run scheduled O&M tasks | You can use OOS to run O&M tasks based on a schedule. For example, you can use OOS to start, stop, and restart ECS instances on a periodic basis to reduce costs. |
Run cross-region O&M tasks | High-availability architectures allow multi-region deployment, which results in increasingly complex O&M tasks. You can use OOS to create templates for O&M operations in different regions to run O&M tasks across regions. |
Perform O&M in multiple regions | If you use resources in multiple regions, synchronization is required to maintain consistency among the resources. For example, you may need to enable the logging feature for Object Storage Service (OSS) buckets in multiple regions at a time. |
You can use OOS as a platform to standardize 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. For more information about the scenarios for which OOS is suitable, see Scenarios.
Benefits
OOS can help you better standardize, manage, and run automated O&M tasks to improve O&M efficiency and security. OOS provides 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
For more information about the OOS benefits, see Benefits.
Use OOS to manage ECS
You can use OOS to manage ECS by performing the following operations:
Configure the permissions for using OOS to manage ECS instances by group
Use the scheduled startup and shutdown feature of OOS to reduce costs
Upgrade the operating system of multiple ECS instances at a time by replacing the system disks
Use OOS to configure password-free logon for multiple ECS instances
Trigger restarts of ECS instances with high CPU utilization based on alerts
