Z Acceptance Grows in BMC 2018 Survey

September 27, 2018

Did Zowe, introduced publicly just a few weeks ago, arrive in the nick of time, like the cavalry rescuing the mainframe from an aging workforce? In the latest BMC annual mainframe survey released in mid September, 95% of millennials are positive about the mainframe’s long-term prospects for supporting new and legacy applications. And 63% of respondents were under the age of 50, up ten points from the previous year.

The mainframe veterans, those with 30 or even 40 years of experience, are finally moving out. DancingDinosaur itself has been writing about the mainframe for about 35 years. With two recently married daughters even a hint of a grandchild on the way will be the signal for me to stop. In the meantime, read on.

Quite interesting from the BMC survey was the very high measures among executives believing in the long-term viability of the mainframe. More interesting to DancingDinosaur, however, was the interest in and willingness to use new mainframe technology like Linux and Java, which are not exactly new arrivals to the mainframe world; as we know, change takes time.

For example 28% of respondents cited as a strength the availability of new technology on the mainframe and their high level of confidence in that new technology. And this was before word about Zowe and what it could do to expand mainframe development got out. A little over a quarter of the respondents also cited using legacy apps to create new apps. Organizations are finally waking up to leveraging mainframe assets.

Also interesting was that both executives and technical staff cite application modernization among the top priorities. No complaints there. Similarly, BMC notes executive perception of the mainframe as a long-term solution is the highest in three years, a six point increase over 2016! While cost still remains a concern, BMC continues, the relative merits of the Z outweigh the costs and this perception continues to shift positively year after year.

The mainframe regularly has been slammed over the years as too costly. Yet. IBM has steadily lowered the cost of the mainframe in term of price performance. Now IBM is talking about applying AI to boost the efficiency, management, and operation of the mainframe data center.

The past May Gartner published a report confirming the value gains of the latest z14 and LinuxONE machines: The z14 ZR1 delivers an approximately 13% total capacity improvement over the z13’s maximum capacity for traditional z/OS environments. This is due to an estimated 10% boost in processor performance, as well as system design enhancements that improve the multiprocessor ratio. In the same report Gartner recommends including IBM’s LinuxONE Rockhopper II in RFPs for highly scalable, highly secure, Linux-based server solutions.

Several broad trends are coming together to feed the growing positive feelings the mainframe has experienced in recent years as revealed in the latest survey responses. “Absolute security and 24×7 availability have never been more important than now,” observes BMC’s John McKenny, VP of Strategy for ZSolutions Optimization. Here the Z itself plays a big part with pervasive encryption and secure containers.

Other trends, particularly digitization and mobility are “placing incredible pressure on both IT and mainframes to manage a greater volume, variety, and velocity of transactions and data, with workloads becoming more volatile and unpredictable,” said Bill Miller, president of ZSolutions at BMC. The latest BMC mainframe survey confirms executive and IT concerns in that area and the mainframe as an increasingly preferred response.

Bottom line: expect the mainframe to hang around for another decade or two at least. Long before then, DancingDinosaur will be a dithering grandfather playing with grandchildren and unable to get myself off the floor.

LinuxONE is a Bargain

September 21, 2018

LinuxONE may be the best bargain you’ll ever find this season, and you don’t have to wait until Santa brings it down your chimney. Think instead about transformation and digital disruption.  Do you want to be in business in 3 years? That is the basic question that faces every organization that exists today, writes Kat Lind, Chief Systems Engineer, Solitaire Interglobal Ltd, author of the white paper Scaling the Digital Mountain.

Then there is the Robert Frances Group’s  Top 10 Reasons to Choose LinuxONE. DancingDinosaur won’t rehash all ten. Instead, let’s selectively pick a few, starting with the first one, Least Risk Solution, which pretty much encapsulates the LinuxONE story. It reduces business, compliance, financial, operations, and project risks. Its availability, disaster recovery, scalability and security features minimize the business and financial exposures. In addition to pervasive encryption it offers a range of security capabilities often overlooked or downplayed including; logical partition (LPAR) isolation, and secure containers.

Since it is a z dedicated to Linux, unlike the z13 or z14 z/OS machines that also run Linux but not as easily or efficiently,  As the Robert Frances Group noted: it also handles Java, Python; and other languages and tools like Hadoop, Docker, other containers, Chef, Puppet, KVM, multiple Linux distributions, open source, and more.  It also can be used in a traditional legacy environment or used as the platform of choice for cloud hosting. LinuxONE supports tools that enable DevOps similar to those on x86 servers.

And LinuxONE delivers world class performance. As the Robert Frances Group puts it: LinuxONE is capable of driving processor utilization to virtually 100% without a latency impact, performance instabilities, or performance penalties. In addition, LinuxONE uses the fastest commercially available processors, running at 5.2GHz, offloads I/O to separate processors enabling the main processors to concentrate on application workloads, and enables much more data in memory, up to 32TB.

In addition, you can run thousands of virtual machine instances on a single LinuxONE server. The cost benefit of this is astounding compared to managing the equivalent number of x86 servers. The added labor cost alone would break your budget.

In terms of security, LinuxONE is a no brainer. Adds Lind from Solitaire:  Failure in this area erodes an organization’s reputation faster than any other factor. The impact of breaches on customer confidence and follow-on sales has been tracked, and an analysis of that data shows that after a significant incursion, the average customer fall-off exceeds 41% accompanied by a long-running drop in revenues. Recovery involves a significant outlay of service, equipment, and personnel expenses to reestablish a trusted position, as much as 18.6x what it cost to get the customer initially. And Lind doesn’t even begin to mention the impact when the compliance regulators and lawyers start piling on. Anything but the most minor security breach will put you out of business faster than the three years Lind asked at the top of this piece.

But all the above is just talking in terms of conventional data center thinking. DancingDinosaur has put his children through college doing TCO studies around these issues. Lind now turns to something mainframe data centers are just beginning to think about; digital disruption. The strategy and challenges of successfully navigating the chaos of cyberspace translates into a need to have information on both business and security and how they interact.

Digital business and security go hand in hand, so any analysis has to include extensive correlation between the two. Using data from volumes of customer experience responses, IT operational details, business performance, and security, Solitaire examined the positioning of IBM LinuxONE in the digital business market. The results of that examination boil down into three: security, agility, and cost. These areas incorporate the primary objectives that organizations operating in cyberspace today regard as the most relevant. And guess who wins any comparative platform analysis, Lind concludes: LinuxONE.

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.
