Allowlisted GA: You can expose the host ID of a Compute Engine

## Feature Feature **Allowlisted GA**: You can expose the host ID of a Compute Engine instance to verify its physical location in relation to other compute instances in your Google Cloud organization. Use compute instance proximity in a zone to optimize latency-sensitive workloads or improve the reliability of your applications. For more information, see[View the physical location of a Compute Engine instance](https://cloud.google.com/compute/docs/instances/view-instance-topology). ## Feature Feature **Generally available**: The [C4D](https://cloud.google.com/compute/docs/general-purpose-machines#supported%5Fdisk%5Ftypes%5Ffor%5Fc4d)machine series supports Hyperdisk Throughput. For more information, see[About Hyperdisk Throughput](https://cloud.google.com/compute/docs/disks/hd-types/hyperdisk-throughput)and [Hyperdisk Throughput performance limits](https://cloud.google.com/compute/docs/disks/hyperdisk-perf-limits#hdt-perf).
