Attract Young Techies to the Z

September 14, 2018

A decade ago DancingDinosaur was at a major IBM mainframe event and looked around at the analysts milling about and noticed all the gray hair and balding heads and very few women, and, worse, few appeared to be under 40, not exactly a crowd that would excite young male computer geeks. At the IBM introduction of the Z it had become even worse; more gray or balding heads, mine included, and none of the few Z professional female analysts that I knew under 40 were there at all.

An IBM analyst relations person agreed, noting that she was under pressure from IBM to get some young techies at Z events.  Sounded like Mission Impossible to me. But my thinking has changed in the last couple of weeks. A couple of discussions with 20-something techies suggested that Zowe has the potential to be a game changer as far as young techies are concerned.

DancingDinosaur covered Zowe two weeks ago here. It represents the first open source framework for z/OS. As such it provides solutions for development and operations teams to securely manage, control, script, and develop on the mainframe like any other cloud platform.

Or, to put it another way, with Zowe IBM and partners CA Technologies and Rocket Software are enabling users to access z/OS using a new open-source framework. Zowe, more than anything before, brings together generations of systems that were not designed to handle global networks of sensors and devices. Now, decades since IBM brought Linux to the mainframe IBM, CA, and Rocket Software are introducing Zowe, as a new open-source software framework that bridges the divide between modern challenges like IoT and the mainframe.

Says Sean Grady, a young (under 30) software engineer at Rocket Software: Zowe to me is really cool, the first time I could have a sustained mainframe conversation with my peers. Their first reactions were really cynical, he recalls. Zowe changed that. “My peers know Linux tools really well,” he notes.

The mainframe is perceived as separate thing, something my peers couldn’t touch, he added. But Linux is something his peers know really well so through Zowe it has tools they know and like. Suddenly, the mainframe is no longer a separate, alien world but a familiar place. They can do the kind of work they like to do, in a way they like to do it by using familiar tools.

And they are well paid, much better than they can get coding here-and-gone mobile apps for some startup. Grady reports his starting offers ran up to $85k, not bad for a guy just out of college. And with a few years of experience now you can bet he’s doing a lot better than that.

The point of Zowe is to enable any developer, but especially new developers who don’t know or care about the mainframe, to manage, control, script, and develop on the mainframe like any other cloud platform. Additionally, Zowe allows teams to use the same familiar, industry-standard, open-source tools they already know to access mainframe resources and services.

The mainframe is older than many of the programmers IBM hopes Zowe will attract. But it opens new possibilities for next generation applications for mainframe shops desperately needing new mission-critical applications for which customers are clamoring. Already it appears ready to radically reduce the learning curve for the next generation.

Initial open source Zowe modules will include an extensible z/OS framework that provides new APIs and z/OS REST services to transform enterprise tools and DevOps processes that can incorporate new technology, languages, and workflows. It also will include a unifying workspace providing a browser-based desktop app container that can host both traditional and modern user experiences and is extensible via the latest web toolkits. The framework will also incorporate an interactive and scriptable command-line interface that enables new ways to integrate z/OS in cloud and distributed environments.

These modules represent just the start. More will be developed over time, enabling development teams to manage and develop on the mainframe like any other cloud platform. Additionally, the modules reduce risk and cost by allowing teams to use familiar, industry-standard, open source tools that can accelerate mainframe integration into their enterprise DevOps initiatives. Just use Zowe to entice new mainframe talent.

IBM’s z13 Redefines Mainframe Performance, Economics, and Versatility

January 14, 2015

With the introduction of the new IBM z13, the latest rev of the 50-year old mainframe product line introduced today, it will be hard for IT people to persist in the mistaken belief that the mainframe can’t handle today’s workloads or that it is too expensive. Built around an 8 core, 22nm processor, the IBM z13’s 141 configurable cores (any mix of CP, IFL, zIIP, ICF, SAP) delivers a 40% total capacity improvement over the zEC12.

 IBM z113

The z13 looks like the zEC12 but under the hood it’s far more powerful

The IBM z13 will handle up to 8,000 virtual enterprise-grade Linux servers per system, more than 50 per core.  Remember when Nationwide Insurance consolidated 3000 x86 servers mainly running Linux on a System z and saved $15 million over three years, a figure later revised considerably higher. They got a lot of press out of that, including from DancingDinosaur as recently as last May. With the IBM z13 Nationwide could consolidate more than twice the number of Linux servers at a lower cost and the resulting saving would be higher still.

If you consider Linux VMs synonymous with cloud services, the new machine will enable superior Cloud services at up to 32% lower cost than an x86-based cloud. It also will cost up to 60% less than Public Cloud over three years. In almost every metric, the IBM z13 delivers more capacity or performance at lower cost.

IBM delivered an almost constant stream of innovations that work to optimize performance and reduce cost. For example, it boosted single thread capacity by 10% over the zEC12. It also delivers 3x more memory to help both z/OS and Linux workloads. The more memory combined with a new cache design, improved I/O bandwidth, and compression will boost analytics on the machine. In fact, with the z13 you can do in-memory analytics if you want it.

The one thing it doesn’t do is boast the fastest commercial processor in terms of sheer speed. The zEC12 processor still is the fastest but with all the optimizations and enhancements IBM has built in the z13 should beat the z12 in handling the workloads organizations most want to run. For instance, the z13 performs 2X faster than the most common server processors, 300 percent more memory, 100 percent more bandwidth and delivers vector processing analytics to speed mobile transactions. As a result, the z13 transaction engine is capable of analyzing transactions in real time.

Similarly, simultaneous multi-threading delivers more throughput for Linux and zIIP-eligible workloads while larger caches optimize data serving. It also improved on-chip hardware compression, which saves disk space and cuts data transfer time.  Also, there is new workload container pricing and new multiplex pricing, both of which again will save money.

In addition, IBM optimized this machine for both mobile and analytics, as well as for cloud. This is the new versatility of this redefined mainframe. Last year, IBM discounted the cost of mobile transactions on the z. The new machine continues to optimize for mobile with consolidated REST APIs for all z/OS transactions through z/OS Connect while seamlessly channeling z/OS transactions to mobile devices with the MobileFirst Platform. It also ensures end-to-end security from mobile device to mainframe with z/OS, RACF, and MobileFirst products.

For analytics, IBM continues to optimize Hadoop and expand the analytics portfolio on the z13. Specifically, the massive memory capability, up to 10TB, opens new opportunities for in-memory computing. The ability to perform analytics by combining data from different data sources and do it in-memory and in real-time within the platform drives more efficiencies, such as eliminating the need for ETL and the need to move data between platforms, as had previously often been the case. Now, just use Hadoop on z to explore data there within the secure zone of the mainframe. This opens a wide variety of analytics workloads, anything from fraud prevention to customer retention.

In addition to improved price/performance overall, IBM announced Technology Update Pricing for z13, including AWLC price reductions for z13 that deliver 5% price/performance on average in addition to performance gains in software exploitation of z13. DancingDinosaur will dig deeper into the new z13 software pricing in a subsequent post.

And the list of new and improved capabilities with the z13 just keeps going on and on.  With security IBM has accelerated the speed of encryption up to 2x over the zEC12 to help protect the privacy of data throughout its life cycle.  It also extended enhanced public key support for constrained digital environments using Elliptic Curve Cryptography (ECC), which helps applications like Chrome, Firefox, and Apple’s iMessage. In addition, the z13 sports a few I/O enhancements, like the first system to use a standards based approach for enabling Forward Error Correction for a complete end-to-end solution.

Finally, IBM has not abandoned hybrid computing, where you can mix a variety of blades, including x86 Windows blades and others in the zBX extension cabinet. With the z13 IBM introduced the new Mod 004 zBX cabinet, an upgrade from the previous Mod 002 and 003.

DancingDinosaur expects the introduction of the z13 along with structural organization changes, will drive System z quarterly financial performance back into the black as soon as deliveries roll. And if IBM stays consistent with past behavior within a year or so you can expect a scaled down, lower cost business class version of the z13 although it may be not be called business class. Stay tuned; it should be an exciting year.
