Well idk, im new from menagement sysadmin, and SSH offer me a terminal... SFTP i think shoul more security with regard that i go desallow ssh(lost terminal) and just upload files...

But on the cloud with out ssh i think i need Cloud SDK or other thing to manipulate system....

I done with SSH, and openssl.... Im not sure of their relationship but i do....

For while, im the team... I need learn to much more about permissions, users and groups
to move forward.
