The challenge


In today's Digital world, many organizations are facing significant challenges. Their decades-old, mainframe-centric application portfolio is expensive, monolithic, rigid, and slow to evolve. Mainframe monoliths have grown over the years with overwhelming complexity. They are usually several million lines of code comprised of a conglomeration of different legacy languages and data stores with various interfaces, evolving coding standards, and poor documentation.

The complexity of these architectures combined with the cost of removing technical debt helps explain why there are still hundreds of billions of lines of COBOL, PL/1 and Natural code being maintained today. It also helps explain why businesses are constrained and limited by their own legacy mainframes.

Mainframes host valuable assets such as processes and rules, data that can fuel innovation, and core-business value - if only they are agile and lean enough. So how do you transform mainframe assets to suppress technical debt, cut costs, and remove inefficiencies? In other words: How do you migrate mainframe assets to private or public Cloud in order to combine both the value of core-business IT assets and the value of Digital?
