About PopUp Mainframe
PopUp Mainframe is an enterprise software vendor that enables mainframe customers to deliver change faster and more cost effectively than ever. Our name is derived from our product’s ability to enable mainframe development teams with an immediately available, fully functioning mainframe. This “pop-up” behaves the same as physical mainframe environments, and supports all popular mainframe subsystem applications, data stores and 3rd party development tools. It revolutionizes mainframe delivery by removing the most commonplace of challenges – bottlenecks – and dramatically reduces the cost of change.
The PopUp Mainframe X and Z Editions provide a functionally equivalent environment to z/OS to ensure the behaviour is predictable, regardless of the platform chosen. Separate editions offer flexibility for customers who want to be able to choose between x86 / cloud-based platforms (X Edition) or running on LinuxONE, or inside the mainframe IFL/KVM Linux environment (Z Edition).
By providing you with your own low-cost, on-demand environments, PopUp Mainframe revolutionizes mainframe delivery.www.popup-mainframe.com
