# AWS - Required permissions

When it uses Snowflake, Tonic Structural orchestrates the creation, usage, and deletion of AWS components. The required permissions are taken from the IAM user or IAM role that is used based on the [configuration in the workspace settings](/app/setting-up-your-database/snowflake/connecting-to-snowflake.md#snowflake-azure-storage-location-aws-credentials).

Note that these permissions are a starting point. Based on your exact AWS setup, you might need to add other permissions. For example, if you use AWS Key Management Service (KMS) on your S3 buckets, then you might need to grant AWS KMS access.

The following example policy allows Structural to properly orchestrate jobs in your AWS infrastructure. It assumes that you use default names for objects in AWS, and that your source and destination S3 bucket names begin with the `tonic-` prefix.

```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::tonic-*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:GetObjectVersion",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion",
                "s3:PutObjectTagging"
            ],
            "Resource": "arn:aws:s3:::tonic-*/*"
        },
        {
            "Effect": "Allow",
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::tonic-*",
            "Condition": {
                "StringLike": {
                    "s3:prefix": [
                        "*"
                    ]
                }
            }
        }
    ]
}

## 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://docs.tonic.ai/app/setting-up-your-database/snowflake/before-you-create-a-snowflake-workspace/snowflake-aws-instance-profile-permissions.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.
