An Intellyx Brain Candy Brief
Everyone knows the mainframe is the beating heart of the enterprise. That’s why there is such high organizational resistance to anyone touching it, even if some of the changes necessary to modernize the codebase running on it in the context of the enterprise’s application stack are overdue.
PopUp Mainframe delivers code-and-component-complete virtual mainframe environments onto cloud or local hardware in minutes, so DevOps teams can safely observe changes and module installations, in order to predictably run functional, performance and reliability tests.
These “PopUps” are readily available turnkey emulators with identical codebases, captured using underlying modern IBM Z technologies such as IBM ZD&T and IBM TAZ, and running on x86 architectures, or now, on the IBM LinuxONE architecture, so the clones can be managed by Linux admins rather than requiring mainframe SMEs to take the time and expense of setting up another LPAR.
The service works with BMC and IBM mainframe development tools right out of the box, or just drop a PopUp call in the GitHub actions pipeline or Jenkins and it configures a fresh test mainframe target in your private or public cloud. Please note that as tempting as it may be, these simulated LPARs are set up for making fixes and improvements, and they will not handle production traffic loads.
