Introduction to Cloud Asset Inventory

Cloud Asset Inventory is a storage service that keeps a five week history of Google Cloud Platform (GCP) asset metadata. It allows you to export all asset metadata at a certain timestamp or timeframe.


Export asset metadata at a timestamp

The Cloud Asset API allows you to export all the asset metadata at a given timestamp to a Cloud Storage file.

Export asset history

The Cloud Asset API can get the history of multiple assets for a given timeframe. This shows you all the create, delete, and update events for the specifed assets over time.

Supported policy types

The Cloud Asset API currently supports the following policy types in GCP:

Key Concepts


An asset refers to a GCP resource. Examples of resources include Compute Engine virtual machines (VMs), Cloud Storage buckets, and App Engine instances. An asset contains resource metadata and additional metadata set on a resource, such as a Cloud Identity and Access Management (Cloud IAM) policy.

Asset content type

Cloud Asset Inventory supports the following asset content types:

  • Resource: Resource metadata of a GCP asset.

  • IAM Policy: Metadata of the Cloud IAM policy set on a GCP asset.

Asset snapshot

An asset snapshot is the set of available assets under a Resource Manager project or organization at a timestamp.

Asset history

For a given asset, asset history includes all metadata create, delete, and update events between timestamp T1 and T2.
