# AWS post-deployment verification

After you have deployed the authentication template in Amazon Web Services (AWS), verify that it was successfully deployed. In Cortex Cloud, select **Data Sources & Integrations → Cloud Accounts**. Verify the following:

* The original cloud instance remains in "Pending" state. For more details on pending instances, see Understand pending instances.
* A new cloud instance appears in the cloud accounts list (separate from the pending instance).
* The new cloud instance shows status "Connected".
* The discovery scan starts automatically for every discovered account.
* Assets appear in the **Asset Inventory** as discovery progresses.

## Troubleshooting AWS onboarding

If no new cloud instance appears:

* Check the CloudFormation stack status in the AWS console. The status should be **CREATE\_COMPLETE**.
* Check the Lambda execution logs in AWS CloudWatch for errors. If the Lambda notification to Cortex Cloud is not executed, Cortex Cloud does not create a new cloud instance in Connected stated.
* You can [Manually connect an instance](https://app.gitbook.com/s/mxWuY3s7AUvWfzCV9p1A/deployment-steps-and-checklist/cloud-service-provider-csp-onboarding/manually-connect-a-cloud-instance) to create the instance from the pending cloud instance.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-5.x/configure-cortex-xdr/cortex-xdr-data-sources/cloud-service-provider-csp-onboarding/amazon-web-services-cloud-onboarding/aws-post-deployment-verification.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
