Cloud KMS locations

Within a project, Cloud KMS resources can be created in one of many locations. These represent the geographical regions where requests to Cloud KMS regarding a given resource are handled, and where the corresponding cryptographic keys are stored. You should consider the network performance implications of the Location you choose to host Cloud KMS resources.

Types of locations for Cloud KMS

There are three types of locations where you can create Cloud KMS resources.

  • Regional locations: A regional location consists of zones in a specific geographical place, such as Iowa.

  • Multi-regional locations: A multi-regional location consists of zones spread across a general geographical area, such as the United States.

  • The global location: There is a special location for Cloud KMS resources called "global". When created in the global location, your Cloud KMS resources are available from zones spread around the world.

Interactions with resources in a location close to you are more likely to be fast and reliable. Choose a specific region if the users and services that depend on a Cloud KMS resource are geographically concentrated. Remember that users and services who are far away from the location chosen may experience higher latency.

When you use multi-regional locations or the global location, read operations, like keyRings.list will be served by a data center close to the requesting user or service. However, write operations, like keyRings.create, must propagate to multiple data centers when performed on multi-region or global resources, and will be slower as a result. If your usage of Cloud KMS involves many read operations from users and services around the world, or involves very few write operations, consider creating multi-region or global resources.
