# Required AWS instance profile permissions for Amazon Redshift

When it uses Amazon Redshift, Tonic Structural orchestrates the creation, usage, and deletion of AWS components.

The required permissions to do so are taken from the instance profile role of the machine that runs Structural's server. This role (EC2) needs the permissions listed below.

These policies 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 buckets begin with the `tonic-` prefix.

Note that these permissions are starting point. Based on your exact AWS setup, you might need to add additional permissions.

The required permissions are as follows:

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