I have run the command netstat -t in my host OS terminal window after I have stopped all services and the following is logged:

root@ba7c427:~# netstat -t
Active Internet connections (w/o servers)

So the host OS has setup some connections with amazon cloud.
Is this normal and if so why is it making those connections ?

Hi there, You can see the network requirements here: https://www.balena.io/docs/reference/OS/network/2.x/#network-requirements. We use AWS to host our services, and the requests you are seeing are either from the Supervisor (which comes bundled with balenaOS), which communicates with our API for various reasons (fetching environment variables, status checks, etc.), or from the VPN, which is used to be able to SSH into a device from the dashboard, for example.
