Solo: A Mainframe Story (Special Edition)

In today’s world, it’s almost impossible for any mainframe operations to work solo: going it alone in terms of the expertise, skills and resources required to succeed, writes Mark Wilson, RSM Partners.

Digital Denial: Why You Can’t Trust the Application Economy

The NYSE and a major airline shut down and, in the case of the airline, shuts down twice is just over a month. Major retailers and a Federal employee databases get hacked. This seems like IT service levels from 1965 not 2015.

Does anyone still believe the application economy can actually work the way it should?

IBM z14 Model ZR1: A Smaller Mainframe for a Larger World

On April 10, 2018, IBM announced their latest mainframe offering, the IBM z14 Model ZR1. This announcement came hot on the heels of the original z14, which was delivered less than a year earlier in July 2017. So why the new model? And what does it mean to mainframe users out there?

What GDPR Means for Mainframe Storage, Archive and Backup

On April 27, 2016, the European Union passed regulation 2016/679, more popularly known as the General Data Protection Regulation (GDPR). On May 25, 2018, GDPR implementation began, and enforcement activities started. So which organizations are affected by GDPR regulation, and what are the most difficult IT hurdles to overcome?

Mainframe apps

While a large chunk of the world seems to think that mainframes are out of date and barely hanging on by the skin of their teeth in organizations that haven’t woken up to modern computing techniques, the rest of us know that mainframes, particularly the z14, are the most secure platforms for computing on the planet, and provide the backbone for 70 percent of the top 500 companies.

Lost on Z

Help! Lost on Z!

Is it a misconception that mainframe professionals find it hard to get help?  When we talk about non-mainframe technology, there seems to be a myriad of platforms with impressive worldwide community support, actively helping each other on a daily basis.  In other words, what you find there is, if you are struggling to find an answer to a problem, or simply trying to find some better ways do something, then you generally post a question online and seek feedback from the community. Do we mainframe professionals lack such an ecosystem? Is it because of a lack of enthusiasm from experts to chime in on discussions to help out? Is it because of a lack of a solid single social media platform to discuss our challenges? Or is because there are too many platforms, and that we all are stretched too thin on each one, and thereby lack strength in numbers to have meaningful discussion?

Demystifying Cloud for Mainframe Managers

The IBM 360 mainframe made its debut in April 1964. With the unprecedented ability to perform 229,000 calculations per second, it became the enterprise platform for transaction-heavy, critical applications. With the emergence in the mid-1980s of mid-range systems (such as SUN’s RISC processor) as well as PCs networked with servers, many thought the mainframe would go the way of the dinosaur. However, in the early 1990s IBM introduced the System/390 family with a groundbreaking computing capacity of 1,000 MIPS (million instructions per second). Since then mainframe computing capacity has increased by more than 30% year-over-year.

The Great Disconnect

Do CICS programmers / JavaScript programmers know what it is they’re working on?  Sure they know how their programs work and how they interface with other modules, and so on, but do they know exactly where in the business they are used, and do they know how important they are to the business?  And do business managers properly relay the critical nature of what they ask for to everyone down the line?

Betty White

Does McKinsey Hate Betty White?

Betty White rocks.  I mean, she hosted Saturday Night Live—and won an Emmy for it—at the age of 88.  At 93, she is still winning awards for shows like Hot in Cleveland and Off Their Rockers, where she is also executive producer.

McKinsey apparently thinks Betty White is out of line.  At least that’s the way it seems based on their advocacy of “two-speed IT,” wherein the mainframe is allowed to slowly plod along while Agile/DevOps innovation is restricted to newer web platforms.

Mainframe Batch

Mainframe batch challenges – and solutions

The ancient datacenter game of tug-of-war between the need for more computing power, and the need to more closely control ongoing IT costs is never-ending, and continues, as intensely as ever, in today’s large business datacenters.

And with the mainframe enclosed firmly within its no-holds-barred silo, the game is more dramatic than it has ever been.  With IT folks outside the silo reminding everyone that ongoing mainframe costs are a drag on the new agile development efforts, those IT folks within the silo remind others that the mainframe is responsible for 75% or more of business revenue, and that access from outside the silo is driving up their operational costs.  We’ve all heard these arguments, and to be fair, they’re all true.
