    "Statement": [
        {
            "Action": [
                "pricing:*"
            ],
            "Effect": "Allow",
            "Resource": "*"
        },
        {
            "Action": [
                "ec2:Describe*"
            ],
            "Effect": "Allow",
            "Resource": "*"
        }
