CHAPTER 2

Creating a Mainframe Virtualized Environment: Requirements and Choices

Several factors that drive the configuration of the mainframe virtualized environment need to be taken into account when you define the requirements for virtualized systems. The most salient requirement is the use case—the objective that is to be achieved by utilizing the virtual systems. Once you define the use case, you can finalize the other requirements. These include access to the systems, the number of systems, hardware specifications, and data sharing.

After the environment has been built, another important consideration is how software updates and upgrades ...
