Optimize Your System z ROI with z Operational Insights (zOI)

Hopefully all System z users are aware of the Monthly Licence Charge (MLC) pricing mechanisms, where a recurring charge applies each month.  This charge includes product usage rights and IBM product support.  If only it was that simple!  We then encounter the “Alphabet Soup” of acronyms, related to the various and arguably too numerous MLC pricing mechanism options.  Some might say that 13 is an unlucky number and in this case, a System z pricing specialist would need to know and understand each of the 13 pricing mechanisms in depth, safeguarding the lowest software pricing for their organization!  Perhaps we could apply the unlucky word to such a resource.  In alphabetical order, the 13 MLC pricing options are AWLC, AEWLC, CMLC, EWLC, MWLC, MzNALC, PSLC, SALC, S/390 Usage Pricing, ULC, WLC, zELC and zNALC!  These mechanisms are commercial considerations, but what about the technical perspective?

Why Can’t You Buy IBMz Mainframe Services from AWS?

The IBMz mainframe is the most powerful, scalable and secure platform on the planet. It’s also the most TCO-efficient. If you have any doubts about that, just take a look at these blogs: “Turn Out The Lights…The Party’s Over! Mainframes Rout Commodity Servers!and “VMware’s Success = Distributed Computing’s Failure in Masquerading as a Mainframe.

Should you call time on your existing mainframe development environment?

The traditional 3270 mainframe development environment deserves respect. It has enabled developers to create and support some of the world’s most enduring business-critical software applications running on ‘Big Iron’ boxes around the word. Many of these core systems continue to deliver today for banks, government departments and large enterprises, decades after they first went live.

2020 vision

I was working recently with a mixed bag of people from a company, who were trying to predict the future and see how that company needed to change in order to get where they thought they ought to be going. One issue came up fairly quickly, and that was that 2020 isn’t that far ahead. As a result, the group started to think about 2025 as date for the changes to be made. The room had a mixture of IT people, execs, a variety of managers, and a number of people from different parts of the organization. I thought it would be interesting to contemplate some of the ideas that came up at the session.

The Mainframe: Three Dimensional Thinking In IT

This is not an article on multidimensional databases, 3D rendering, or spatial databases, but rather how CIOs in IT think, based on their education, experience and professional motivations.

A good friend of mine, Pete, recently asked me how many servers does it take to equal a mainframe? He’s actually quite a smart guy, a Salesman and former software Engineer, but has never worked in the mainframe business, and knows nothing about it. But it was a fair question, and I had to answer “x”—a variable. This did not satisfy him at all, as you might imagine, but that’s the truth—it depends upon many variables.

Settling for less

I was reading the news on CNN recently about a power outage in California, which reminded me of some serious black outs in Costa Rica a while back. A friend was there on business, and it ruined an important business meeting that he had spent months setting up. It also reminded me of the northeast blackout that happened here in 2003, which caused some problems for us at home.

Mainframe optimization on the high seas

Being in the mainframe business for about 10 years now, I hear interesting anecdotes from time to time, often from the most unlikely sources. I may have taken some liberty with the title, but it’s a true story, and it relates well to what I see in the mainframe business all the time.

Mainframes are used increasingly by major banks and financial institutions

Do you think the mainframe is dead? A dinosaur, an ancient piece of technology that has outlived its usefulness like cathode ray tubes, rotary dial telephones, and dial-up modems?

I have some news for you. The mainframe has adapted: it is alive and well with major banks and financial institutions continually growing their use of mainframes. In fact, mainframes are at the core of their technology strategies. The reason why? Mainframes deliver functionality and reliability unmatched by any other platform.

Data Centers, Mainframes and the rest

Data Centers, Mainframes and the rest!

When compared to an x86/distributed server environment, the operational costs of the power consumption versus IBM’s Mainframe z Systems are half, while the performance is 30 percent greater (using z Systems as an example.)

So let’s think about that for a minute!

X86/Distributed server power consumption is double that of an IBM Mainframe?

Bringing DevOps to your mainframe

The days of waterfall software development on a mainframe are coming to an end. It’s no longer tolerable for end users to have to wait two years for a new application to be written and delivered to a spec that, by then, is two years out of date. The inflexibility of the waterfall methodologies make them uncompetitive in the modern mainframe environment. What’s needed are the faster, more flexible, processes associated with Agile and DevOps ways of working. But what does an organization need to do in order to move from their old way of working to this new way – a way that can bring regular and frequent updates to any application to suit the needs of the users?
