Google Cloud management regions overview

Google Cloud management regions and locations

Clusters created with GKE on AWS are located in a AWS region. When you create a cluster, you specify both an AWS region for your cluster and a Google Cloud region that manages the cluster.

Each Google Cloud region can manage clusters in a specific set of nearby AWS regions. For example, the Google Cloud region us-west1, located in Oregon, manages clusters in two AWS regions: us-west-1 in Northern California and us-west-2 in Oregon. Managing your clusters from nearby Google Cloud regions improves availability and reduces the latency of cluster management operations.

GKE on AWS includes the cluster's Google Cloud region in the cluster's resource name. For example, a cluster named my-cluster created in project my-project on region us-west1 has a resource name of projects/my-project/locations/us-west1/awsClusters/my-cluster. By contrast, the AWS region is part of the cluster resource. You can specify it in the aws_region field of API calls.

Data locality

To manage your clusters, the GKE Multi-Cloud API must store information about your cluster's state in the Google Cloud region you specified when creating the cluster. This data doesn't include workload-specific data (which is stored in your cluster's region) but does include information such as AWS resource IDs and public key infrastructure (PKI) data.

If your application needs to store its data in a particular geographic region, specify an AWS region and its associated Google Cloud management region that comply with your requirements when you create your clusters.

You can fetch the most up-to-date list of current AWS regions supported by a Google Cloud region by running the following gcloud command:

gcloud container aws get-server-config --location GOOGLE_CLOUD_REGION

Replace GOOGLE_CLOUD_REGION with the name of the Google Cloud region you're querying.
