# VPC/VNet Gateway Resizing

> Resize Aviatrix gateways for performance or cost on VPC/VNets

You can resize your Aviatrix gateways to improve performance or save costs on
your VPCs and VNets. Gateways can be resized in the Aviatrix PaaS console from
Cloud Resources > Cloud Assets > VPC/VNets & Subnets.

The following sizes are currently supported:

* AWS: small, medium, large, and extra large
* Azure: small, medium, and large

For more information about performance sizing, see
[Gateway Sizing Best Practices Guide](/docs/cloud/platform-administration/manage/gateway-sizing-bp-paas).
The VPC or VNet with which the gateway is associated must be onboarded to
Aviatrix PaaS before resizing it.

To resize a gateway on a VPC or VNet, do the following:

1. Go to *Cloud Resources > Cloud Assets > VPC/VNets & Subnets*.
2. Locate the VPC or VNet that contains the gateway you want to resize.
3. Click *Manage* for that VPC/VNet and verify that the gateways listed are the
   ones you want to resize.
4. Select the new *Performance Size* and click *Save*.
