Cloud KMS in Trusted Cloud versus Google Cloud

Cloud Key Management Service (Cloud KMS) lets you create and manage cryptographic keys for use in compatible Trusted Cloud services and in your own applications. This page describes the differences between the Trusted Cloud and Google Cloud versions of Cloud KMS.

For more detailed information about Cloud KMS, see the Cloud KMS overview and the rest of the Cloud KMS documentation.

Key differences

There are some differences between the Trusted Cloud version of Cloud KMS and the Google Cloud version. Some notable differences include the following:

  • Key tracking and key usage details are not supported in Trusted Cloud by S3NS.
  • Hardware (Cloud HSM) keys are not supported in Trusted Cloud by S3NS.
  • The EKM over internet protection level is not supported in Trusted Cloud by S3NS.

A more detailed list of differences is provided in the rest of this section. If you are already familiar with Google Cloud, we recommend that you review these differences carefully, particularly before designing an application to run on Trusted Cloud. We also recommend reviewing the general differences between Google Cloud and your universe in the Trusted Cloud by S3NS overview.

global location

The global location exists for Trusted Cloud but contains only a single region, u-france-east1. Resources stored in the global region satisfy the same residency requirements as those stored in u-france-east1. Choose the global location for your Cloud KMS resources if you want to use CMEK to protect resources in the global location. Otherwise, you should create your Cloud KMS resources in the u-france-east1 region.
