Lots of jobs during build. But after that, 10 guys on a security rotation 24/7, 5 guys on 'take stuff out of boxes and put it in racks to replace failed components' duty, and 5 more to do all the certifications and paperwork (who might be offsite).

I think an Amazon datacenter is going to have a few more people than that because it's so huge. I just looked at the satellite image of their Ashburn datacenter in Google Maps. I saw maybe like 50-ish cars.

One thing to note, as mentioned in my reply to your main comment, is that many of those cars are not owned by local jobholders in the community but rather contractors which travel to various data centers across the US as maintenance requires.
