Currently i am running Postfix on GCP, Ubuntu 18.04 LTS as Google Computer Engine. You can open INGRESS (port 25 inbond). However you cannot open ENGRESS (port 25 outbond). So you should use outside SMTP for sending. In my experience, Mailgun and Amazon SES are good for sending. They offer special ports such as 2525, 2587 for relaying.
