Attention, the question: who was at the origins of virtualization? For all the love for the products of this company, the answer "VMware" will be wrong. The pioneers in this market were General Electric, Bell Labs and IBM.
Creation of a virtual machine
Already in the early sixties, the IBM portfolio consisted of dozens of different systems. Each new generation was strikingly different from the previous one. Buyers tore their hair out in vain to keep up with the innovations and demands of the new iron. In addition, in those years, the paradigm “one computer at one sitting performs only one task” was still relevant. Need more? Be kind enough to resort to batch processing, when one job is executed on the computer after another without operator intervention. Inconvenient, right? But IBM didn't see this as a problem. Most of the users of their machines belonged to the scientific community. It was enough for them.
