Their cloud management and firewall situation is quite terrible. Not any better or worse than AWS or GCP or Azure, but still quite terrible. It's actually quite neat for large deployments with thousands of containers so you don't need to manually interact with a billion firewalls by just generating all the cloud settings automatically, but for the free trial stuff you're going to need to brute force the security settings web interface until you've checked enough boxes to allow traffic on all ports. As for the 2FA thing, IMO any cloud company like Oracle should enforce that. Companies get stuck with giant bills all the time because someone got into their cloud accounts and started spinning up crypto miners like crazy. Jumping straight into the unnecessarily complicated world of Big Cloud seems like a challenging way to begin learning about servers, you'd probably be better off renting a small VPS somewhere instead. Or running a server in your home network, that'll also work just fine at first!
