In the enterprise IT landscape, there is a persistent myth that the mainframe is a legacy platform on its way out. However, as Bob Jeffcott, Principal Systems Engineer at Software AG, pointed out in a recent webinar, “The reports of the demise of the mainframe are greatly exaggerated.”<\/p>\n\n\n\n
The reality is that IBM Z workloads are actually growing. According to IBM and industry analysts, 70% of mainframe clients are increasing their workloads annually, and 95% of IBM installations still rely heavily on COBOL for their mission-critical applications. But this growth comes with a ceiling: maxed-out capacity, skyrocketing costs, and the constant threat of failing to meet critical Service Level Agreements (SLAs).<\/p>\n\n\n\n
How can organizations handle this growth without the massive disruption of migration? The answer lies in the hardware you already own.<\/p>\n\n\n\n
When faced with a capacity crunch on the General Processor (GP), many organizations feel compelled to undertake a COBOL workload modernization project. Typically, these strategies fall into a few categories:<\/p>\n\n\n\n
But these approaches are fraught with risk. They often involve unpredictable costs, long implementation timelines, and lost functionality when the new system can\u2019t replicate the decades of business logic baked into the original COBOL code. And, they\u2019re often all-or-nothing solutions, meaning that when modernization hits a roadblock, it\u2019s often too late to reconsider.<\/p>\n\n\n\n
