The idea is to get an Outputs similar to

{
  "publicSubnets": [
    {
      "id": "subnet-02d7930bd",
      "az": "us-east-2a"
    },
    {
      "id": "subnet-0a89e59bb",
      "az": "us-east-2b"
    },
    {
      "id": "subnet-04658194f",
      "az": "us-east-2c"
    }
  ],
  "privateSubnets": [
    {
      "id": "subnet-00a9f3a9d6",
      "az": "us-east-2a"
    },
    {
      "id": "subnet-026eed9351,
      "az": "us-east-2b"
    },
    {
      "id": "subnet-0bfabcc5f666637c1",
      "az": "us-east-2c"
    }
  ]
}
