Can you imagine how many documents need to be properly accessed and backed up for legal reasons. I have used it for damn near anything. School registration, rental, home buying, legal reasons. There have to be so many redundancies for me and I'm a nobody. Now imagine all that for a modest company? And how many exist. I can see a decent amount of employees to facilitate that.
That is not what I was talking about. There are still people that need to monitor the code and the storage spaces. Servers don't just magically have space. Especially if they are doing anything on the cloud. Making them accessable is a database feature that has to be daunting.
And I'd bet all that server management is done by a subcontractor in the data center (having worked in enterprise for decades, this is how it's done).
FTEs often don't even touch production, they work things out in Test/Pre-prod, then document it, and hand it off to Change Management and their change vendor (those folks in the data center).
Those change engineers do changes for multiple clients, which makes their time less expensive since they're fully utilized.
