BMC Mainframe Survey Confirms z System Is Here to Stay

November 11, 2016

No surprise there. BMC’s 11th annual mainframe survey covering 1,200 mainframe executives and tech professionals found 58% of respondents reported usage of the mainframe is increasing as they look to capitalize on every infrastructure advantage it provides and add more workloads. Another 23% consider the mainframe as the best option to run critical work.

Driving the continuing interest in the mainframe are the new demands for data handling, scalable processing, analytics, and more. According to the BMC survey nearly 60% of companies are seeing increased data and transaction volumes. They opt to stay with the mainframe for its highly secure, superior data handling and transaction serving, particularly as digital business adds unpredictability and volatility to workloads.

Overall respondents fell into three primary groups: 1) entrenched mainframe shops, 58% that are on board for the long haul; 2) shops, 23% that intend to maintain a steady amount of work on the mainframe; and 3) the 19% that are moving away from the mainframe.  The first two groups, committed mainframe shops, amount to just over survey 80% of the respondents.

Many companies surveyed are focused on addressing the increased workload demands, especially the rapidly growing demand for new applications. But surprisingly, the survey does not directly touch on hybrid cloud, cognitive computing or any of the latest technologies IBM has been promoting, not even DevOps, which can streamline mainframe application development and deployment. “We are not hearing much about a hybrid cloud environments or blockchain yet. Most companies seem to be in the early tire kicking stage, observed John McKenny, BMC Vice President, Strategy and Operations.

Eighty-eight percent of companies in the first group, entrenched mainframe shops, for example, are looking to increase the workloads they run on Java on the mainframe, primarily to address new application demands. It also doesn’t hurt that Java on the mainframe also can help lower data center costs by directing workloads to lower cost assist processors.

Other interesting BMC survey findings:

  • Half of the respondents report keeping 50% of their data on the mainframe and continue to invest in the platform for reasons you already know—security, availability, data serving capability
  • Continued steady growth of Linux in production on the z: 41% in 2014, 48% in 2015, 52% in 2016
  • Increased use of Java on the mainframe report as 67% of respondents cite need to meet growing application demand

Those looking to reduce mainframe presence cited three reasons: 1) perception of high cost, 2) outdated management understanding, and 3) looking for ways to reduce workloads over time.  DancingDinosaur has spoken with mainframe shops intending to migrate off the z and they cite the usual reasons, especially #1 above.

Top mainframe priorities for 2016 according to the BMC survey:  Cost reduction/optimization (65%); data privacy, compliance, security (50%); application availability (49%); application modernization (41%. Responses indicated the priorities for next year haven’t changed at all.

Surprisingly, many of the latest technologies for the z that IBM has touted recently have not yet shown up in the BMC survey responses, except maybe Java and Linux. This would include hybrid clouds, blockchain, IoT, and cognitive computing. IDC, for example, already is projecting cognitive computing to grow at a CAGR of 55.1% from 2016 to 2020. For z shops, however, cognitive computing appears almost invisible.

In some case with surveys like this you need to read between the lines. Where respondents report changes in activity levels driving application growth or the growth of interest in Java or the frequency of application changes and references to operational analytics they’re making oblique references to mobile or big data or even cognitive computing or other recent technologies for the z.

At its best, the BMC notes that digital technologies are transforming the ways in which mainframe shops conduct business and interact with their customers.  Adds BMC mainframe customer Credit Suisse: “IT departments are moving toward centralized, virtualized, and highly automated environments. This is being pursued to drive cost and processing efficiencies. Many companies realize that the Mainframe has provided these benefits for many years and is a mature and stable environment,” said Frank Cortell, Credit Suisse Director of Information Technology.

Compuware and BMC Aim to Lower Mainframe Cost

July 9, 2015

Last February, Compuware and BMC announced a joint initiative to coordinate the use of their respective tools, BMC Cost Analyzer, BMC MainView, and Compuware Strobe, to reduce mainframe software licensing cost. DancingDinosaur wrote about it here. The announcement made this week confirms that the necessary integration between the various tools has been completed and is working as promised. Compuware this month also introduced the latest rev of its Topaz graphical management toolset for the z.

The tight integration between the BMC and Compuware tools enables mainframe staff to quickly and easily identify tuning opportunities that will have the greatest impact on their monthly software licensing costs. They do this by applying BMC Cost Analyzer’s visual mapping to the detailed batch and transaction information provided by Compuware Strobe. The cost savings result from moving workloads to non-peak periods, running IBM subsystems on fewer LPARs, and capping LPAR utilization.

Driving the need for this is the continuing growth of mainframe workloads, which are being pushed today by mobile workloads and, down the road, by new IoT workloads. These workloads already are driving up the Monthly License Charge (MLC) for IBM mainframe software, which led IBM to initiate z/OS discounts for mobile workloads on the z as well as introduce its new ICAP and country multiplex pricing. Compuware estimates that the integrated tools alone can reduce an organization’s mainframe software licensing costs by 10% or more.

“Mainframe cost conservation is an imperative for public- and private-sector IT organizations attempting to fulfill customers’ escalating digital expectations within ever-limited budget constraints,” said Karen Robinson, a former CIO and now a consultant. “The work BMC and Compuware are doing together is a perfect fit for this universal imperative.”

Besides discounting mobile workloads, IBM also has been actively working to help organizations drive down mainframe costs in other ways. Moving workloads to z assist processors is a top choice. Another is to take advantage of a variety of IBM discounts; DancingDinosaur’s favorite is the Solution Edition program, which offers the deepest discounts if you can live with the constraints it imposes. And, of course using tools like those from Compuware and BMC can save money every month. At a time when mainframe workloads are growing—Did someone say the mainframe was going away?—this is a sure path to relief.

Compuware made a second announcement impacting the mainframe this month. This involved adding capabilities to Topaz, its set of graphical z management tools aimed at millennial workers. The new capabilities address Java on the z, which is a key way to cash in on the savings available by shifting workloads to z assist processors, specifically the zIIP. The announcement is here. Again, DancingDinosaur initially wrote about Topaz earlier this year here.

As Compuware describes it, Topaz for Java Performance delivers comprehensive visibility into the performance and behavior of Java batch programs and WebSphere transactions running on the mainframe—including peak CPU utilization of specific Java methods and classes; garbage collection issues such as memory leaks and excessively long collection intervals; and threads that are blocked or not actually doing useful work.

According to Tonya Robison, VP Legacy Integrations, Conversion, De-commission at Alfa Insurance:  “Topaz is enabling us for a multi-channel, multi-platform future. Its functionality will allow us to work with mainframe and non-mainframe data in a common, visual, and intuitive manner, providing our next-gen developers the same agility and speed as our seasoned IT pros.” Robison is convinced that “products like Topaz will protect our current investments and enable the next generation of application developers.” These are the millennials everyone is trying to attract to the mainframe.

The new release of Topaz, the third this year alone, delivers two capabilities that enhance customers’ ability to maximize value from their mainframe:

  1. Topaz for Program Analysis gives developers intuitive, accurate visibility into the flow of data within their COBOL or PL/l applications—including how data gets into a field; how that field is used to set other fields; and how that field is used in comparisons. This promises to be especially useful for Millennials who may not have a wealth of experience with IBM z Systems.
  1. Topaz for Enterprise Data brings high-speed, compression-enabled host-to-host data copying that exploits IBM z Systems zIIP processors, thus reducing the burden on its general processors. This fast, efficient copying enables developers to complete their work more quickly and at less cost.

Efforts of Compuware, BMC, and others are rapidly changing the mainframe into an agile platform that can rival distributed platforms. Let’s hope the Millennials notice.
