[GO SDK V2] NAT gateway - get availability zone

Question

Hello,

I'm trying to determine the availability zone of a NAT gateway in an account, not just for one, but for a list of NAT gateways one after another.

As far as I understand, when calling `ec2Client.DescribeNatGateways()` the NAT's availability zone is not provided.

In order to get the AZ, I'm doing another API call to `ec2Client.DescribeSubnets` with the NAT's subnet ID,
Only then the AZ is in the output.

As I'm making a multiple API calls, this could be time-consuming.

I was wondering what is the most efficient way to determine the NAT's AZ?

Thank you,

Ori Adler

You can pull the list of AZs from the ENIs. Here is the CLI:

```
aws ec2 describe-network-interfaces --filters Name=interface-type,Values=nat_gateway --query NetworkInterfaces[*].AvailabilityZone
```

The response to `DescribeNatGateways` does include the subnet id which can be used with `DescribeSubnets` to determine the availability zone.
