Discussing criticisms of the mainframe, because it remains integral countless global household names.
New technologies square measure perpetually being introduced into our lives solely to be taken a number of years later, however amidst all the toing-and-froing of the past few decades in massive enterprise IT, there has been one constant: the mainframe. Despite false claims of the death of the mainframe, it remains the bedrock of the many organisations, powering high-volume transactional workloads and mission important business functions. The mainframe’s strategic connection is merely growing within the digital age; indeed, sixty four per cent of mainframe-powered organisations are now planning to run more than half their mission-critical workloads on the platform, a rise from fifty seven per cent in 2018.
The reliability, power, measurability, security and transactional value potency of the mainframe square measure all business-critical virtues distinctive to the platform, and that they type the premise for why numberless organisations square measure protective the mainframe’s position in their IT atmosphere. However, despite its tested advantages and therefore the growing confidence enterprises have in its ability to power mission-critical workloads, some unashamed pundits still discussion its future. There upon in mind, let’s jest at a number of these fallacies by staring at the 3 biggest mainframe myths to uncover the fact-based truth regarding IT’s longest mainstay.
- The evolution of IT infrastructure – from mainframe to server-less
Myth 1 – you need to re-platform to require advantage of the cloud
Consumers don’t apprehend their mobile banking app is retrieving knowledge from a mainframe and making it available on their device via an app that’s hosted within the cloud, nor do they extremely care. the sole issue that matters to a shopper is that the merchandise or service they’re victimization is being delivered during a high-quality manner and helps them approach their lives easier. to supply the simplest client expertise, firms got to use the simplest attainable platform, and whereas some area unit higher than others at ending bound tasks, no single system is that the best for everything.
Adopting a two-platform, one-speed IT strategy supported the mainframe and the cloud is therefore useful. each platforms offer their several strengths, and each platforms will run at identical speed and un compromised quality needed from Agile and DevOps processes. This empowers development groups to initiate at identical speed, and with the essential quality, in spite of platform and while not the strain of migrating off systems that area unit verified to figure.
Some misguided people area unit fast to leap on the cloud-first bandwagon, once the actual fact is, history shows organisations that try migrations off the mainframe typically produce business disasters for themselves and therefore the customers they serve. Ultimately, two-platform, one-speed it’s a higher, cheaper and quicker method for mainframe-reliant organisations to form innovative progress in comparison to the risky different of migrating decades of important knowledge over to the cloud.

Myth 2 – Mainframe development groups can’t be agile
When it involves implementing Agile Development processes, it’s not simply a matter of whether or not the hardware is trendy enough. The culture, processes and tools close the platform square measure equally necessary because the hardware for enterprises making an attempt to boost the speed, quality and potency of their software system development and delivery.
Adopting Agile or DevOps practices, and modernizing tools and processes, can build it potential for developers of any expertise to act with the mainframe. Through this approach, enterprises will rest simple that the platform is well adaptable to new tools, compatible with new technologies and, crucially, accessible for developers new the mainframe. However, there isn’t a one-stop answer to modernizing mainframe software system delivery and therefore the tools at intervals it – it’s a method.
At the start of the journey, exchange obsolete green-screen environments with trendy, intuitive day is vital, as this creates associate improved developer expertise on the mainframe. Organisations will then begin automating advanced, repetitive processes, like testing. A comprehensive set up can ultimately alter siloed mainframe development and operations groups to make cross-platform Agile/DevOps groups and start to figure as a part of the broader IT department.
Myth 3 – COBOL contains asbestos
First, cobol is nothing over program syntax that once compiled into machine language drives calculate resources. Of the ever-increasing list of 1000+ syntax’s within the world, no single one is usually best. each program syntax has professionals and cons advisedly. What’s distinctive concerning Cobol is that the compiler. IBM has done a masterful job at unceasingly up the Cobol compiler each few months. These enhancements fine tune the ensuing machine language so it will most effectively and with efficiency drive the newest and greatest calculate resources within the engineering marvel that’s the mainframe. That’s why the world’s economy truly runs on over 220 billion lines of Cobol code, which variety is increasing on a daily basis.
Second, within the Age of software package, code that’s verified to be economical associate degreed effective is one among the best assets of an organisation. changing verified programming language code to unproved Java code can seemingly increase the lines of code by fifty per cent, decrease the performance and reliableness, increase security risks, and increase total prices. That’s on the far side crazy. Instead, associate degree organisation’s precious time, cash and energy ought to be endowed in delivering new options that customers care concerning and removing technical debt which will improve future flows inside your software package delivery method.
Third, today’s incoming developers square measure polyglot programmers. By necessity, they’re snug operating with a range of programming languages, and cobol is simply another one to feature to the list. For Cobol to fit seamlessly into the trendy programmer’s skill set, fashionable DevOps tools square measure needed to change developers to figure on multiple forms of programs with ease and confidence. fortuitously, these tools square measure without delay obtainable and growing. a contemporary IDE, for instance, provides developers a well-known and most well-liked expertise inside they will code in nearly any language on most platforms – demonstrating however programming language can find time for nicely with different languages the trendy developer uses ofttimes.
The modern mainframe reality
The mainframe continues to be an integral part within the IT infrastructure of myriad home names round the world, and – like humorist – rumours of its death are greatly exaggerated. However, it will still be tough for firms to grasp however the mainframe will be incorporated into their trendy IT strategy. firms don’t need to sacrifice the responsibility, security and power of the mainframe, nor do they need to. Through adopting trendy tooling and methodologies like Agile Development and DevOps, enterprises will retain the various advantages the mainframe has got to supply, integrate the platform with newer technologies, and succeed bigger rate, quality and potency in software package development and delivery.
