Cloud Pub/Sub is available for a specific region. What does this mean? Please confirm

Question

Does the release notes statement that Cloud pub/sub is available now in a specific region mean that the data movement (pushing into the topic, subscribing to a topic, storing message) happens within that region only? GDPR requirement (Data residency) that data shall not move from the geography where the data originated from. Please confirm.

Answer 1

Google Cloud Pub/Sub is a global service, available from everywhere. It is not possible to choose where you want your Pub/Sub service to be, but it will be in the closest region to your project location. The fact that is available in a new region means that now that region has the necessary infrastructure to host a Pub/Sub service.

Here you can see the location of Google Cloud products, and also the release notes on Pub/Sub

[EDIT]

Despite this, there are some ways to help you ensure compliance:

• As mentioned above, Pub/Sub takes the best effort to keep your data in the closest location to you the source of publication, and once it is stored, that data will not moved without your explicit action.
• Pub/Sub provides monitoring on data storage location, thus you can track any potential violations and take action by discarding the backlog using Pub/Sub's seek's functionality or ensuring that it is quickly processed.
• Risk can be limited by reducing message retention duration.
