with cloud being the talk of the industry these days. how pervasive are SRE roles. I would wager a good system admin | SRE can save a company thousands if they provisioned their own hardware i.e colo instead of cloud instances etc
The decision for where the hardware will exist may be advised by SREs, but is generally not exactly in their wheelhouse. SREs tend more towards lowering the cost and maximizing the utilization of whatever methods the company as a whole decides to use.
