BMC Mainframe Survey Bolsters z-Hybird Computing

For the seventh year, BMC conducted a survey of mainframe shops worldwide. Find a copy of the study here and a video explaining it here. Most of the results probably won’t surprise you:

  • 90% of respondents consider the mainframe to be a long-term solution, and 50% expect it will attract new workloads.
  • Keeping IT costs down remains the top priority—not exactly shocking—as 69% report cost as a major focus, up from 60% from 2011.
  • 59% expect MIPS capacity to grow as they modernize and add applications to address expanding business needs.
  • More than 55% reported a need to integrate the mainframe into enterprise IT systems comprised of multiple mainframe and distributed platforms.

The last point especially suggests IBM is on the right track with hybrid computing. IBM also is on the right track in terms of keeping costs down, especially by enabling organizations to maximize the use of specialty engines in an effort to reduce consumption of costly GP MIPS.  The specialty engine advantage continues with the new zEC12, incorporating the same 20% price/performance boost, essentially more MIPS bang for the buck.

Two-thirds of the respondents were using at least one specialty engine. Of all respondents, 16% were using five or more engines, a few using dozens.  Not only do specialty engines deliver cheaper MIPS but they often are not considered in calculating software licensing charges, which lowers the cost even more.

About the only change noticeable in responses year-to-year is the jump in the respondent ranking of IT priorities. This year Business/IT alignment jumped from 7th to 4th in priority ranking. Priorities 1, 2, and 3 (Cost Reduction, Disaster Recovery, and Application Modernization respectively) remained the same.  Priorities 5 and 6 (Efficient Use of MIPS and Reduced Impact of Outages respectively) fell from a tie for 4th last year.

The greater emphasis on Business/IT alignment isn’t exactly new. Industry gurus have been harping on it for years.  Greater alignment between business and IT also suggests a strong need for hybrid computing, where varied business workloads can be mixed yet still be treated as a single system from the standpoint of efficiency management and operations. It also suggests IT needs to pay attention to business services management.

Despite the mainframe’s reputation for rock solid availability and reliability, the survey also noted that 39% of respondents reported unplanned outages. The primary causes for the outages were hardware failure (cited by 31% of respondents), system software failure (30%), in-house app failure (28%), and failed change process (22%). Of the respondents reporting outages, only 10% noted that the outage had significant impact. This was a new survey question this year so there is no comparison to previous years.

Respondents (59%) expect MIPS usage to continue to grow. Of that growth, 31% attribute it to increases in legacy and new apps while 9% attributed it to new apps. Legacy apps were cited by 19% of respondents.

In terms of modernizing apps, 46% of respondents planned to extend legacy code through SOA and web services while 43% wanted to increase the flexibility and agility of core apps.  Thirty-four percent of respondents hoped to reduce legacy app support costs through modernization.

Maybe the most interesting data point came where 60% of the respondents agreed that the mainframe needed to be a good IT citizen supporting varied workloads across the enterprise. That’s really what zEnterprise hybrid computing is about.

    Very well positioned the subject! Other good point to be considered is that nowadays companies, mainly financial industry, have to put zSeries into the middle of the circle when talking about app modernization. Mainframe can and have to coexist with all platforms. Of course that zBX brings a new way to do that, but all platforms have their space into the ecosystem. Application modernization is a good subject that connect all those things.
