Learn how to do systems admin in the cloud your current employer/industry favors - as a longtime Microsoft platform admin who picked up PowerShell over the past decade to do AD/Exchange/Lync (Skype), Azure was easiest to slide into. Learn how that cloud’s networking works, especially with existing on-prem stuff, and do so in its command line interface. Learn how to do those things in Terraform and Ansible.

Be a sysadmin for developers. Help those bright young kids who are network-blind figure out why their stuff isn’t talking to other stuff. Help them when they can’t work out how to deal with the corporate web proxy or why their cloud bills are so high (did they check how many cores their database instance really needed? Did they pick a good VM size, or should they have gone with something with a higher RAM/CPU ratio?)
