When you release a new software version or update service configurations — such as managed O&M settings or O&M notification settings — configure service upgrades so that users can update their service instances to the new version directly from the Compute Nest console.
How it works
After you configure service upgrades, service instances run predefined upgrade operations based on the settings you provide — for example, replacing OS images or running installation commands.
Upgrades apply to two scopes:
-
Service Settings — Updates service-level settings (managed O&M, O&M notification configurations) without touching the underlying application. This scope is always included and cannot be deselected.
-
Resource Configurations — Updates the resource stack based on changes in the Resource Orchestration Service (ROS) template or Terraform template. Use this scope when cloud resources or the application itself need to be updated.
If you enable the Service Instance Rollback option, users can also roll back a service instance from a new version to a previous one.
