Do not go gentle into that excellent night…
COBOL, the programming language extensively applied to run Tier 1/mission-critical applications on mainframe pcs – and popularly imagined of in some trendy youthful corners to be a relic of the dark ages – is essentially in impolite excellent well being.
That’s in accordance to a new survey by Micro Target now, which finds that following much more than sixty decades in the output natural environment, COBOL code bases are – potentially startlingly to some – continuing to increase, as companies modernise applications.
In brief, if COBOL had been a man or woman it would now be holding a Independence Move – but producing much more use of it than lots of expected. (“Do not go gentle into that excellent night”)
COBOL Applications Common 9.9 Million Lines…
The common COBOL code foundation,now runs to 9.9 million strains, vs . 8.four million in 2017 – reflecting ongoing financial commitment, re-use and growth in core business techniques by individuals running applications published in the language, Micro Target uncovered.
Describing it as a “dependable resolution that will carry on to increase and thrive”, Chris Livesey, Micro Focus’s senior VP of application modernisation and connectivity explained: “Thanks to the authentic design’s readability, adaptability and portability, COBOL provides tremendous benefit for organizations as a trusted resolution.”
(The survey further more uncovered that 70 p.c of enterprises expect to modernise present applications as component of their strategic alter programmes, rather than retiring them, while sixty three p.c explained that they will be improving upon present COBOL techniques in 2020.)
So what do individuals modernising applications published in/around COBOL want to be notably conscious of? Computer Business Critique asked the experts…
Modernising Your COBOL Applications
Thilo Rockmann, Chairman and COO, Switzerland’s LzLabs, told us on a call: “The critical detail is that the new natural environment, wherever that sits, integrates neatly into the enhancement chain of whatever you are likely to develop…”
“If there are breaks from an business point of view concerning what you are likely to establish in just one space and [how that brings together with] a different enhancement chain, or enhancement approach, you will generally have friction.
“This is just one of the places in which companies ordinarily have troubles, as if you want to retain COBOL applications running on a mainframe that observe a different cycle to your Java, Python, enhancement, that can result in challenges.”

He additional: “The technique desires to be as incremental as attainable.
“The language by itself is less of an challenge. A very long time back I had to retain some COBOL code and it wasn’t that tricky, despite my generally (formerly) making use of C++ and Java.
“What is important for developers is the potential to check the new code that you wrote around the mainframe, and check it in the natural environment in which your developers sit, and not require specified hrs [time slots] to do it on the mainframe.
“[Modifications are often vital to] run your mainframe much more effectively: if you run it inefficiently you are likely to fork out a ton much more: big mainframe applications use a ton of CPU time…”
Keith Banham, mainframe R&D manager at Macro four, additional: “Modernising mainframe applications can contain a range of different possibilities. Enterprises should not mechanically go down the route of rewriting code or re-platforming devoid of acquiring an in general method that can take account a selection of different aspects.”
“Cost is definitely an important consideration.
“The assumption is that mainframe pricing is high relative to other platforms – so lots of organisations want to go as a great deal as attainable off the mainframe to cut down MIPS intake. Even so, IBM has introduced new pricing possibilities you should take into consideration. Now, if you are running new workloads, you can use the new Tailor-made Suit Pricing, which is more simple, frequently much more cost helpful and closer to the Cloud/SaaS intake design. So, never believe – do your sums and see if it is truly worth the go.”
In the end, of course, business leaders want to weigh up the challenges of re-producing code vs . the challenges of a long term lack of mainframe abilities weighing them up versus the challenges of business interruption posed by a main migration off mainframes.
Succession planning also has to be taken into account. Due to the fact there’s a whole ton of COBOL code out there and it clearly isn’t wafting off the cloud anytime shortly.
