# Mapping Aviatrix Standard Gateway Sizes to VM Instance Sizes

> On the Cloud Fabric > Scaling > Auto Right-Sizing tab, you can click Aviatrix Standard Sizes to show standard sizing for Aviatrix Spoke, Specialty, and Transit Gateways (AWS and Azure) and how they map to AWS and Azure VM instance sizes.

On the Cloud Fabric > Scaling > Auto Right-Sizing tab, you can click **Aviatrix
Standard Sizes** to show standard sizing for Aviatrix Spoke, Specialty, and
Transit Gateways (AWS and Azure) and how they map to AWS and Azure VM instance
sizes. These are the sizes you see when you resize a gateway instance according
to recommendations.

| Cloud and Gateway Type | VM Instance Size                                                                                                                                                                                                         |

* Any sizes tagged as Non-Prod are not recommended for a Production deployment.
* Any sizes tagged as Non-HPE are not recommended for an HPE deployment.

When you resize a gateway, the Size Recommendation field shows the current size
and the recommended (Aviatrix standard) size, with the actual gateway instance
size shown in brackets.
