What is Mainframe Modernization?


Technically speaking, mainframe modernization simply refers to the process of improving an enterprise’s existing mainframe footprint in several aspects, including interface, code, performance, maintainability, and cost. Some would say that modernizing the mainframe means replacement of these legacy systems with commodity servers, which is a bold claim since it calls for a drastic change.In mainframe modernization, one should look at the bigger picture because, ultimately, the goal is to achieve a connected ecosystem. A business should determine where and how resources should be allocated to create a computing framework that integrates implementations across the organization. Essentially, modernizing a mainframe system involves the adoption of applicable modern philosophies and methodologies using existing applications or installing modern hardware or software. The most cost-effective approach is to take a look at what’s currently working and build upon that; mainframe modernization should build upon existing COBOL systems and incrementally improve or add capabilities. Replacement should be a last resort so as to preserve the functionality of existing platforms.Modernization of COBOL systems can be achieved by integrating them with more modern cloud and mobile applications. Although referred to by many as a legacy system, COBOL applications are still used to power 65% of enterprise software …
