# Arm Virtual Hardware
- [Overview](./arm_virtual_hardware.md#overview)
- [Getting started](./arm_virtual_hardware.md#getting-started)
- [Useful Links](./arm_virtual_hardware.md#useful-links)
## Overview
Arm® Virtual Hardware is an accurate representation of a physical System on Chip and runs as a simple application in a
Linux environment for easy scalability in the cloud and removes dependency from silicon availability.
Powered by Amazon Web Services (AWS), developers can launch Amazon Machine Image
(AMI) running as a virtual server in the cloud. The Arm Virtual Hardware is configured with the Corstone™-300 MPS3
based Fixed Virtual Platform (FVP), compiler and other tools.
### Getting started
To take advantage of Arm Virtual Hardware, you would need to have an AWS account and follow the steps below:
1. Login to your AWS account.
2. Go to the AWS Marketplace and search for [Arm Virtual Hardware](https://aws.amazon.com/marketplace/pp/prodview-urbpq7yo5va7g).
3. Subscribe to the Arm Virtual Hardware Amazon Machine Image.
4. Launch the AWS instance.
To access the Arm Virtual Hardware AWS instance via ssh, accept the prompt to generate a *.pem* key
while creating the instance or add it later.
You can then access the AWS instance over ssh: `$ ssh -i <mykey.pem> ubuntu@<ec2-ip-address>`.
It may be necessary to change the permissions for mykey.pem with `$ chmod 400 mykey.pem`.
### Useful Links
Note that you can register to receive free AWS credits to use Arm Virtual Hardware from
[here](https://www.arm.com/company/contact-us/virtual-hardware).
You can find more information about Arm Virtual Hardware [here](https://arm-software.github.io/VHT/main/overview/html/index.html).
Once you have access to the AWS instance, we recommend starting from the
[quick start guide](../quick_start.md#Quick-start-example-ML-application) in order to get familiar
with the ml-embedded-evaluation-kit. Note that on the AWS instance, the FVPs are available under:
- `/opt/VHT/VHT_Corstone_SSE-300_Ethos-U55`
- `/opt/VHT/VHT_Corstone_SSE-300_Ethos-U65`
- `/opt/VHT/VHT_Corstone_SSE-310`
In order to view the FVP window when launching on the AWS instance a VNC is required.
