It can sometimes feel frustrating to try to figure out how to do DevOps. That’s because DevOps is not about tools—there are lots of different tools that can help you succeed at DevOps. Nor is it about any really specific set of practices; although DevOps prioritizes things like automation and communication, it does not prescribe […]
The Competitive Advantages of Modern SCMs
Source code management (SCM) is not a new concept. It has been in existence since around 1980, when Revision Control System (RCS), one of the first major SCMs, was released. But that doesn’t mean SCM today is the same as it was decades ago. Modern SCM tools do much more than their predecessors. They handle […]
Shift-Left Testing, Continuous Integration and the Mainframe
“Mainframe” is one of the oldest terms in tech. “Shift-left” is much newer. You may not think, then, that mainframes and shift-left testing have much in common. But you’d be wrong. Shifting testing to the left can deliver tremendous benefits, even in the context of mainframe applications. Let us explain. What Is Shift-Left Testing? Shift-left […]
Discovering Business Logic in z/OS Applications
Change is constant, and it is the responsibility of those who manage information to adapt. As the economy grows and changes, and as our society implements new regulations and phases out older regulations, our applications need to change with them. We present two capabilities available from IBM that can enhance your ability to manage changes […]
Achieving Open and Integrated Development with IBM Z
“DevOps” and “mainframe” are not words you often hear in the same sentence. Yet, the reality is that even in our current age of DevOps, mainframes remain the mainstays of many companies’ IT infrastructure. That’s why it’s critical for organizations to find ways to bring mainframe software delivery up to speed with modern DevOps practices, […]
Going Cloud-Native with IBM Z as a Hybrid Cloud Platform
When people use the phrase “they don’t make ‘em like that anymore,” 100-year-old bridges, Jon Snow’s sword and American muscle cars often come to mind. If the topic of discussion happens to be computer technology, however, mainframes are without a doubt the Valyrian steel of the enterprise and lucky for us, are still in production […]
CAP Theorem No Match for Mainframes
One of the biggest problems in modern distributed computing is data management. These days data are spread out all over the place. As a result, getting the data you need, exactly when you need it, becomes a problem. Wider distribution creates more network latency. If you have a system in which some machines are in […]
IBM Extends z/OS Toward DevOps Again
A few months ago, I wrote about the release of Zowe, the first Open Source project based on z/OS. Zowe is a framework for including z/OS in your applications with less pain than we have traditionally suffered. IBM supported this project as part of its view that enterprises need to have interoperability between platforms. This […]
Mainframes: The Cloud Before the Cloud
Here’s something to think about: Despite the fact that IBM stopped manufacturing personal computers in 2005, deciding instead to focus on higher margin business services, the company continues to produce mainframes and by all estimates will continue manufacturing them well into the future. The question is, why? The answer: because there is still significant demand […]
ABO and the Mystical Art of Source Code Compilation
Compilation can make or break the performance quality of an application. A developer might spend weeks creating the most elegant, efficient algorithm known to man, only to have it run at a snail’s pace in production because the compiler used to create the application’s executable binary is old, and not optimized to take advantage of […]
