In my experience DevOps coming from a sysadmin background end up poisoning the well. They’re afraid of developing the right kind of abstractions, block any proposals to do these and before you blink you end up with a mediocre VendorOps team that can do nothing but integrate off the shelf solutions with an unmaintainable mess of yaml / hcl “code”.

They will replicate, the more capable DevOps engineers will leave in frustration and your platform will be taken hostage. Don’t let a single one in.
