For at least the last five years, there’s been a conversation rumbling on about skills shortages in enterprise IT. As a generation of software engineers reach retirement age, it’s becoming harder to hire people with expertise in older languages such as RPG. And as the dominance of Linux as a server operating system increases, admins with an intimate understanding of environments such as IBM i and IBM AIX are becoming thin on the ground.

This may be a controversial opinion for some members of the IBM Power Systems community, who argue that the problem is not a lack of skills, but the fact that companies have allowed old, undocumented code to become technical debt, instead of modernising it gradually over time.

Nevertheless, it’s still a concern for IT decision-makers: if the engineers who know how the code works are leaving the business, and the new generation of developers aren’t ready to take over, that’s a significant risk for the business.

There are several ways to address the problem. The first—and most drastic—is to move away from the Power Systems platform altogether, rewriting your core business systems on a totally different technology stack using the most popular modern platforms and tools.

However, that’s a hugely complex, expensive and risky move. You’re throwing away years of investment in a battle-tested system that has evolved over time to match your precise business needs—and replacing it with a new system that is a completely unknown quantity. When the business depends on it, most companies simply aren’t willing to take that risk.

A better option is a more gradual approach to modernisation. The Power Systems platform can run almost any set of technologies you need it to—so if you want to start building applications in Java, Python or JavaScript and running them on Linux, you can host them side-by-side with your core RPG or C systems on the same box. This makes it easier to replace legacy code component by component, avoiding the need for a “big bang” move to an entirely new application and significantly reducing risk.

Nevertheless, if you can’t—or don’t want to—maintain a team of Power Systems specialists in-house, you still need someone to look after the platform, handle patches and security updates, and develop enhancements for your older applications to ensure they can interact seamlessly with newer systems. That’s where the Meridian Power Cloud comes in.
