Mainframe Modernization Survey 2021

Modernising the legacy application landscape should not necessarily involve complete replacement.

Business risks that make mainframe modernisation an imperative

Business risks

Tales of business application failure in the wake of departing mainframe personnel are legion – and are ringing alarm bells all the way to the board.
