In fact, such systems still exist today. These systems required a large footprint to house enough power and capacity to service a large number of users.

In an enterprise data center, you would see a mixture of these server-computing footprints, mainly because of the silo approach to computing and minimum computing requirements, to host and execute a particular vendor’s application. An enterprise utilizes applications from multiple vendors. Therefore, there is a mixture of Reduced Instruction Set Computing (RISC) and ...
