A capacity allocation is a global reservation of physical nodes for your Cloud Billing account. Your reserved nodes are organized into placement groups (PGs), which represent the specific physical hardware and location of your reserved capacity.

You can view all allocated capacity for your billing account on the Capacity allocations page in the Google Cloud console. From this page, you can filter allocations by region and zone to understand your available capacity in specific locations.

Each capacity allocation entry displays the following information:

• The associated PG
• The total capacity allocated within that PG
• The current usage of that capacity
• The number of provisioned private clouds using that capacity

Additionally, you can view the assigned PG for the clusters on the details page for private clouds.

Note: The total allocated capacity and current usage values reflect the entire Cloud Billing account. However, the listed private clouds show only those within the context of your selected project.

If you require new or additional capacity allocations, contact your Google Cloud account team.

Use a capacity allocation during private cloud creation

When you create a new private cloud, you can select a capacity allocation for your primary cluster by selecting a PG after defining the basic private cloud details. Selecting a PG lets you deploy your cluster on specific physical hardware where you have globally allocated capacity.

To use your capacity allocation during private cloud creation, do the following:

1. In the Google Cloud console, go to the Private clouds page.

   Go to Private clouds

2. Click Create private cloud.

3. Provide the basic private cloud details, including the private cloud name and the region and zone.

4. For the private cloud type, select Standard private cloud or Stretched private cloud.

5. In the Primary cluster section, specify the node type and the number of nodes.

6. In the Placement group list, select a PG to choose your capacity allocation:

   • Standard private cloud: Select an available PG for your selected zone.
   • Stretched private cloud: You must select a PG for each zone to choose your capacity allocation.
   • No PG selection: Only select the No PG selection option if Google Cloud specifically allocated capacity to this private cloud. If you select this option when Google Cloud has not allocated specific capacity to the private cloud, the creation attempt fails.

7. Complete the remaining networking configurations and click Create to provision your private cloud.

Use a capacity allocation when adding a cluster

You can select a capacity allocation when expanding an existing private cloud by adding a new cluster. Selecting a PG ensures that Google Cloud provisions the new cluster's nodes from your designated capacity reservation.

To use your capacity allocation when adding a cluster, do the following:

1. In the Google Cloud console, go to the Private clouds page.

   Go to Private clouds

2. Click the name of the private cloud that you want to expand.

3. Click the Clusters tab.

4. Click Add cluster.

5. Provide a name for the new cluster, and select the node type and the number of nodes.

6. In the Placement group list, select the specific PG from which you want to provision the new nodes to choose your capacity allocation.

7. Click Create to provision the new cluster by using your allocated capacity.

Configure a hybrid private cloud across multiple placement groups

A hybrid private cloud is a deployment model that lets you scale consumption or transition from retiring ve1 hardware by adding clusters in a different PG. This self-service approach eliminates the need for manual support tickets.

To configure a hybrid private cloud, do the following:

1. Create a standard private cloud with a primary cluster in your initial PG. For instructions, see Use a capacity allocation during private cloud creation.
2. Add a new cluster to the private cloud and select a different PG where you have capacity allocated. For instructions, see Use a capacity allocation when adding a cluster.
