I did save one company enough money to finance my salary for the year I worked there, just by removing dead servers provisioned but no longer used. Seems like my predecessors were blind to both cost and the past.
I felt bad for leaving so soon, but good for not having cost them a dime.
AWS architecting class years ago. Awesome instructor said if you want to save money, start deactivating servers. The ones people use... the admins will contact you right away. The others... people started up and forgot about.
