# Requirements
This chapter lists the prerequisites for an optimal use of Genymotion Cloud on Amazon Web Services, Google Cloud Platform, Alibaba Cloud or Microsoft Azure.
# Web browser
To use Genymotion Cloud and view your instances in a web browser, we recommend using Google Chrome 34+ (Mobile or Desktop). Genymotion Cloud is also known to work fine on the following browsers, but may not provide an optimal level of performance.
- Mozilla Firefox 30+
- Opera 22+
- Microsoft Edge 15+
- Safari 11+
- Microsoft Internet Explorer 11+
# Communication
To enable communication from your network to your instance, you need to:
- Allow the connection from your local network to the following ports of your instance (outgoing)
- Update your instance's security group or firewall configuration to allow connection to the following ports (ingoing)
| Rule Description | Port |
|---|---|
| SSH | TCP port 22 |
| HTTP | TCP port 80 |
| HTTPS/WSS | TCP port 443 |
Warning
We do not recommend opening the ADB port. The ADB connection is neither secured nor authenticated. Instead we recommend creating an SSH tunnel, as explained in section Accessing a virtual device from ADB. If you do decide to open the ADB connection, allow this port: Inbound ADB on TCP port 5555 only for your IP addresses.
If you are behind a very restrictive web proxy or a secured company network, please refer to Accessing a virtual device from an enterprise network (NAT).
# Amazon Web Services
Ports are configured in a security group that contains all the firewall rules. In case you need to edit those rules:
- Go to Network & Security > Security groups.
- Select the security group associated with your virtual device.
- From tabs Inbound or Outbound, click Edit.
- Edit rules according to your needs.
# Google Cloud Platform
Ports are configured in network tags that are specific to a firewall rule. Your instance is bound to various network tags.
To edit a firewall rule:
- Go to VPC network > Firewall rules.
- Edit an existing rule by clicking its name and Edit.
# Alibaba Cloud
Ports are configured in a security group that contains all the firewall rules.
In case you need to edit those rules:
- Go to Network & security > Security groups.
- Select the security group associated with your virtual device.
- Click on Configure rules.
- Edit rules according to your needs.
# Microsoft Azure
Ports are configured in Network security groups (NSG). NSGs are usually defined during a virtual machine setup (see Azure Quickstart and Network Security Groups but can also be changed afterwards:
- Go to Network security groups.
- Select the NSG associated with your virtual machine (
your_virtual_machine_name.nsg). - Edit your rules according to your needs in Inbound security rules and Outbound security rules.
