Reminiscing the old server days will remind you how servers used to occupy large floor space.

And business owners had to be very careful about the locality they would lease, power supply, full-time resources, and ensure availability of servers 24*7 to operate a business without any hiccup. And the system administrators would have to be alert all the time because a small issue in the server could put a lot of business things at stake. So, the system administrators had to ensure the good health of servers for critical business applications to function seamlessly.
