Z Open Terminal Emulation

You can spend a lot of time working with the Z and not find much new in terminal emulation. But there actually are a few new things, mainly because times change and people work differently, using different devices and doing new things. Sure, it all goes back to the mainframe, but it is a new world.

Rocket Software’s latest wrinkle in terminal emulation is BlueZone Web, which promises to simplify using the mainframe by enabling users to access host-based applications anywhere and on any type of device. It is part of a broader initiative Rocket calls Open AppDev for Z. From DancingDinosaur’s perspective its strength lies in being Zowe-compliant, an open source development environment from the Open Mainframe Project.This makes IBM Z a valuable open platform for an enterprise DevOps infrastructure.

Zowe is the first open source framework for z/OS. It facilitates DevOps teams to securely manage, control, script and develop on the mainframe like any other cloud platform. Launched in a collaboration of initial contributors IBM, CA Technologies, and Rocket Software, and supported by the Open Mainframe Project. The goal is to cultivate the next generation of mainframe developers, whether or not they have Z experience. Zowe promotes a faster team on-ramp to productivity, collaboration, knowledge sharing, and communication.

This is the critical thing about Zowe: you don’t need Z platform experience. Open source developers and programmers can use a wide range of popular open source tools, languages, and technologies–the tools they already know. Sure it’d be nice to find an experienced zOS developer  but that is increasingly unlikely, making Zowe a much better bet.   

According to the Open Source Project, IBM’s initial contribution to Zowe was an extensible z/OS framework that provides REST-based services and APIs that will allow even inexperienced developers to rapidly use new technology, tools, languages, and modern workflows with z/OS. 

IBM continues to invest in the open source environment through Zowe and other open source initiatives.  Zowe also has help from Rocket Software, which provides a web user interface, and CA, which handles the Command Line Interface. You can find more about zowe here.

IBM introduced Linux, a leading open source technology, to the Z over 20 years ago. In time it has expanded the range of the Z through open-source tools that can be combined with products developed by different communities. This does create unintentional regulatory and security risks. Rocket Open AppDev for Z helps mitigate these risks, offering a solution that provides developers with a package of open tools and languages they want, along with the security, easy management, and support IBM Z customers require.

“We wanted to solve three common customer challenges that have prevented enterprises from leveraging the flexibility and agility of open software within their mainframe environment: user and system programmer experience, security, and version latency,” said Peter Fandel, Rocket’s Product Director of Open Software for Z. “With Rocket Open AppDev for Z, we believe we have provided an innovative secure path forward for our customers,” he adds. Businesses can now extend the mainframe’s capabilities through the adoption of open source software, making IBM Z a valuable platform for their DevOps infrastructure.”

But there is an even bigger question here that Rocket turned to IDC to answer. The question: whether businesses that run mission-critical workloads on IBM Z or IBMi should remain on these platforms and modernize them by leveraging the innovative tools that exist today or replatform by moving to an alternative on-premises solution, typically x86 or the cloud.

IDC investigated more than 440 businesses that have either modernized the IBM Z or IBMi or replatformed. The results: modernizers incur lower costs for their modernizing initiative than the replatformers.  Modernizers were more satisfied with the new capabilities of their modernized platform than replatformers; and the modernizers achieved a new baseline for which they paid less in hardware, software, and staffing. There is much more of interest in this study, which DancingDinosaur will explore in the weeks or months ahead.
