I am primarily a system administrator (among other roles) and have been looking to make the jump into DevOps for a while. The main issue seems to be that almost no company hires for entry-level or intermediate DevOps positions, only senior with 5+ years experience of very specific tools. My guess is most of those get filled internally as lateral moves from regular developer roles.
Go for consulting/body shops, they're always hungry for people they can pay as juniors while they're sold as seniors.
Some do hire entry level DevOps! There's a big demand for it, from where I'm standing.
Those roles indeed get filled internally by devs, but it's tough since I don't think most devs want them. :p
that's still sysadmin
Yes, but 'modernized' with generally higher salaries.
