## Virtual Machine CPU and Memory Configurations

This table provides the CPU and memory specifications of the virtual machine
instance supported for Aviatrix Edge Gateway deployment.

| **Deployment Type** | **Hardware Profile** | **Storage Requirements** | **Note**            |
| ------------------- | -------------------- | ------------------------ | ------------------- |
| Small               | 2 vCPU - 4GB         | 64 GB                    | \<1Gbps Throughput  |
| Medium              | 4 vCPU - 8GB         | 64 GB                    | \<5Gbps throughput  |
| Large               | 8 vCPU - 16GB        | 64 GB                    | \~10Gbps throughput |
| X-Large             | 16 vCPU - 32GB       | 64 GB                    | \~10Gbps throughput |

<Note>
  We recommend that you do not change the Edge VM resource allocation after
  deploying it. Aviatrix support may not be able to assist with any issue that
  occurs on a system with customized resource allocation.
</Note>

Over subscription of host resources can lead to a reduction of performance and
your instance could become unstable. We recommend that you follow the guidelines
and the best practices for your host hypervisor.

## Aviatrix Edge Gateway Ports and Protocols

The Aviatrix Edge Gateway requires outbound access to communicate with the
Aviatrix Controller. You must allow access on the specified ports on your
firewall.
