Feature stages

This topic describes the lifecycle stages that Google Distributed Cloud Hosted (GDCH) features might transition through, such as the following launch stages:

There are also the following end-of-life stages:

Launch stages


At Preview, a feature is ready for testing by customers before adopting it for production use at GA. Preview offerings are often publicly announced, but are not necessarily feature-complete, and Google provides no Service Level Agreements (SLA) or technical support commitments for these. Unless stated otherwise by Google, Preview offerings are intended for use in test environments only. Features in Preview are typically expected to reach GA within 12 months, but this might vary.

General Availability (GA)

General Availability (GA) features are production ready, though not always universally available. Some GA features might only be available to a limited group of customers. For customers with increased accreditation standards, some GA features are not available to use.


Accredited features are GA features that have received approval from the concerned accreditation agencies and are ready for customer onboarding. Customers with regulated deployments might require some production-ready features be accredited before they can use them. This feature type is identified as a Significant Change Request (SCR) feature and is undergoing further review. This feature has not received an Authority to Operate (ATO) within a regulated environment. Reach out to your Infrastructure Operator (IO) for questions regarding feature accessibility.

End-of-life stages


Marking an offering deprecated is an announcement that GDCH is discontinuing a service or feature that it supports. See the Google Cloud deprecation policy for more information: https://cloud.google.com/terms/deprecation.


Decommissioning an offering means that the feature is no longer available. Calling decommissioned software can result in unpredictable behavior or invalid responses.

Feature gates

Feature gates are a mechanism used by your Infrastructure Operator (IO) to manage features that are in the following feature stages:

Based on your deployment, the features in the following table might not be available to use. Check with your IO for more information.
