CloudOps Orchestration Service (OOS) uses templates to define the O&M operations that require orchestration. The templates are classified into public templates and custom templates. You can use the OOS process configuration editor to create templates. The template content uses the YAML or JSON format. OOS provides public templates for use and reference. Before you use a public template, you must check the operations to be performed in the template and observe the template performance in a test environment. You can also create custom templates to perform O&M operations based on your business requirements.
