Committed use discount recommender

The committed use discount (CUD) recommender helps you to optimize the resource costs of your Compute Engine virtual machine instances. Its recommendations are generated automatically based on the usage metrics gathered by Cloud Billing during the previous 30 days. You can use these recommendations to purchase additional commitments and further optimize your Google Cloud costs.

Refer to Understanding commitment recommendations for more information, or Applying committed use discount recommendations for details on how to apply them to your account.

Warning:

Before applying recommendations in the Cloud Console or using the API, ensure that impacts are assessed by a reviewer. The reviewer should have the knowledge to assess impacts identified in recommendations, as well as impacts specific to your infrastructure and business. Applying recommendations without proper assessment could result in unexpected changes, such as issues with system performance, poor reliability, or loss of required permissions. If you choose to apply recommendations without human review, ensure that you have set up a rollback process before making any changes.

Permissions

Required permissions

To view CUD recommendations:

• recommender.usageCommitmentRecommendations.get
• recommender.commitmentUtilizationInsights.get
• recommender.usageCommitmentRecommendations.list
• recommender.commitmentUtilizationInsights.list

To modify the state of VM instance sizing recommendations:

• recommender.usageCommitmentRecommendations.update
• recommender.commitmentUtilizationInsights.update

Note: Granting your users these permissions might give them a partial view of the resource for which the recommendation is generated. For more information, see the Recommender Overview.

Granting permissions

To grant the required permissions, assign one of the following roles:

• To view recommendations only, assign the Viewer (roles/viewer) role.
• To view and modify recommendations, assign the Owner (roles/owner) or Editor (roles/editor) role.

If you have opted in for CUD discount sharing, you will need to assign different IAM roles:

• To view recommendations only, assign the Billing Account Viewer (roles/billing.viewer) role.
• To view and modify recommendations, assign the Billing Account Administrator (roles/billing.admin) role.

Learn how to assign these roles

Note: To change the IAM policy for a project, you must be granted a role that includes the resourcemanager.projects.setIamPolicy permission. For more details about IAM permissions, see IAM overview.
