You can get virtual server for $4/month. Installing proprietary software and registering to some service, that may "upgrade" to premium tier anytime, is pretty off-putting.

My home firewall blocks all traffic except for incoming SSH from 3 IP addresses in the world. One of those is my virtual server.
If I'm in a hotel with my laptop I run the first command to set up an SSH tunnel to my "home" computer through the cloud virtual server. That listens on my laptop to port 8888 and forwards it through the cloud virtual server to my home computer's SSH daemon listening on port 22
ssh -X -f -C -L 8888:home.mydomain.com:22 -N user@cloud.mydomain.com
ssh -p 8888 user@localhost
