Welcome to the Tearsheet Podcast. I'm Zack Miller, Tearsheet's editor in chief.

Building on top of a bank – the way Banking as a Service enables a tech company to do – has some interesting side effects. Who controls the traffic in the network? Regulators are increasingly interested in sorting out how financial institutions partner with tech firms and that means understanding how all these constituent parts fit together.

Today’s guest is Andrew Coward, general manager of IBM’s software networking business. His team works with financial institutions on SDN – or software defined networking – to bring control and policy management back into their infrastructure regardless of where their application lives. Andrew explains what SDN is and how we got here in history. We discuss how SDN plays into the future of financial services, too. I ask Andrew about the rollout of 5G and how that impacts banks and traditional FIs.

Andrew Coward is my guest today on the Tearsheet Podcast.
