Virtualization

The first steps of virtualization date back to approximately half a century where concerns such as heterogeneity, portability, stability, and more efficient use of resources have begun to take their first steps. Desktop virtualization has a history of the 60's, while application virtualization is only a few years old.

It all started with IBM (International Business Machines Corporation) and its long list of varieties of systems with their successive generations creating some customer conflicts. Several problems have been emerging, always associated with sequential execution of processes, a real disorder for processing multiple tasks, so the Mainframe S/360, a single access system to maintain compatibility and respond to the need to perform multiple tasks (Batch Jobs) emerged.
