Capgemini Revives Mainframes with a Shot of AI

Generative AI is giving new life to old mainframe computer systems by providing smarter coding helpers and automation tools that make it easier to manage and improve these aging setups. This week, Capgemini introduced a new toolkit to update old COBOL applications and databases, helping businesses modernize their mainframes. At the same time, Rocket Software, celebrating 35 years in enterprise IT, revealed new services like automated problem detection and an easy-to-use coding assistant that speaks plain language. According to a recent market study, many companies are now choosing to rework their mainframe applications using AI tools instead of moving everything to the cloud. John Schick from ISG explained that mainframes still play an important role for many businesses, and AI is helping these systems work better and last longer. Adding to this trend, IBM recently announced its newest mainframe, the z17, which includes powerful AI processors and will be available in June. IBM’s previous model, the z16, was very successful in the market. Big banks like Goldman Sachs and Bank of America have already seen benefits from AI-assisted coding tools that improve efficiency. A recent survey found that 80% of business and IT leaders are planning to use AI coding assistants to help manage and update their old systems. Rocket Software’s CEO, Milan Shetti, pointed out that one great thing about AI is that it can explain complex mainframe tasks in simple language anyone can understand. Rocket is also using AI to train new engineers and address the shortage of mainframe experts. IDC’s Stephen Elliot said AI is a key tool helping IT teams modernize core systems and work more efficiently, especially when skilled staff are hard to find. Capgemini is focused on helping companies move from mainframes to a mix of cloud and on-site systems. Their expert Franck Greverie said many businesses want to keep mainframes but also want safer ways to update their systems. Lisa Dyer from IT firm Ensono added that AI makes it easier for cautious companies to try new approaches without risking their critical applications. As AI technology improves, it offers businesses more flexible and safer ways to modernize their old but important systems.
