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?

Mainframing in the 2020’s

There are a countless number of articles on the subject of mainframe computing, and whether or not you should stay with it or replace it with a “more modern” technology.  As you can probably well imagine, most vendors that are mainframe-specific will recommend that you stay on the platform because it is cheaper and more reliable than any other platform out there.  This is actually true, most particularly for the large-scale revenue-generating applications that are in use by the Fortune 500 today.  In fact BMC recently released its annual mainframe survey study which indicated that mainframe use is likely to continue in this year and beyond, and even increase somewhat.  I get opportunities to talk with many CFOs and CIOs of the largest companies in the world and I believe that point.  I am actually not hearing a lot of anti-mainframe sentiment; instead I hear more of the common issues facing business today — my business is hard, competition is tough, I need to cut costs and increase market share.

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users to have to wait two years for a new application to be written and delivered to a spec that, by then, is two years out of date.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?

Will Mainframers adopt DevOps?

Mainframes are under siege. You might like to picture the mainframe department as some medieval castle surrounded by invading troops. There’s no actual fighting going on, but gradually the forces of distributed computing are waiting for the survivors inside the fortress to die of hunger (or in our case, retire through old age). One day, there will be no-one left to defend the castle – one day, there will be no-one left to run the mainframe.
