Welcome to the stack: the end of mainframe banking:
Many years ago, enterprise software was written to run on mainframe computers. […] The traditional banking business model mirrors the mainframe: a vertically integrated, all-in-one solution with all the resources and tools needed to deliver banking products and services in one big (black) box. In the context of the 20th century competitive and technological landscape this worked fine. It was the optimal solution. But like the mainframe of the computing world, the all-in-one “big iron” approach to banking is no longer the optimal business model with which to efficiently and profitably serve the banking customers of today. A new approach, predicated on assembling specialist providers of the component elements required to deliver end products and services will prove to be the new optimal business model for banking. Welcome to the (banking) stack.
Another industry ripe for disruption.
