# Enable Cloud OS Image table

# Enable Cloud OS Image discovery {#ariaid-title1}

* Release version: Yokohama

* ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read

Enable the Cloud OS Image \[cmdb_ci_cloud_os_image\] table to store the cloud OS image records for Amazon AWS Cloud, Microsoft Azure Cloud, Google Cloud Platform (GCP), Oracle Cloud Infrastructure (OCI), and IBM Cloud.

## Before you begin

* Ensure that the latest versions of the following applications are installed:
  * Discovery and Service Mapping Patterns
  * CMDB CI Class Models
  {#enable-cloud-os-image-discovery-pattern__ul_sgv_rqm_lfc}
* Ensure that the application scope is the CMDB CI Class Models application.

Note:  
Cloud Provisioning and Governance (CPG) doesn't support the New Cloud Image (cmdb_ci_cloud_os_image) table. If you're currently utilizing CPG Provisioning flows or have intentions to do so, don't migrate to the new Image Model.

Role required: admin

## About this task

Each cloud service provider offers OS images to launch a Compute/VM instance. Cloud Discovery stores the discovered Image \[cmdb_ci_os_template\] table. This table is a dependent class on \[cmdb_ci_logical_datacenter\] or \[cmdb_ci_cloud_service_account\]. The new Image model creates one
record for each public Image (object id) irrespective of the service account and populates them in the Cloud Image
\[cmdb_ci_cloud_os_image\] table. There for, the new model reduces the number of records in the CMDB  
Note:  
If you have Discovery and Service Mapping Patterns version 1.10.0- November 2023, proceed to the following procedure. If you have an earlier version, see the Knowledge Base article [KB1000183](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1000183).

This direct population reduces query complexity and improves query performance.")
