AWS SimpleDB IAM Access

We have nodejs applications running in AWS EC2. Instances should be disposable. We setup the apps to log to AWS SimpleDB. But creating a user to access SimpleDB was more difficult then I expected. In IAM, I created a user and applied two policies using the policy generator:

{
  "Statement": [
    {
      "Action": [
        "sdb:*"
      ],
      "Resource": [
        "arn:aws:sdb:*:1111222333:domain/node*"
      ],
      "Effect": "Allow"
    }
  ]
}

{
  "Statement": [
    {
      "Action": [
        "sdb:ListDomains"
      ],
      "Resource": [
        "arn:aws:sdb:*:1111222333:*"
      ],
      "Effect": "Allow"
    }
  ]
}

The number is the AWS account number
The key for success was the second policy for Listing Domains

This is an excellent way to connect and manage SimpleDB from the Chrome browser
