Amazon Virtual Private Cloud (VPC) is a commercial cloud computing service. Users can create virtual private clouds, which can subsequently be connected to a local network and centrally managed over IPsec tunnels.
You can connect your Amazon VPC to your Sophos UTM on AWS if Sophos UTM on AWS has a static public IP address. The entire configuration of the VPN connections has to be done in the Amazon environment. Afterwards you just import the connection data using your Amazon access data or a configuration file.
