In recent weeks, back-end infrastructure work and other backend-related issues impacted various online and consumer banking services, including DBS and Citibank in Singapore.

Simple front-facing customer experiences that we’ve become accustomed to today can often mask considerable complexity on the backend. The service delivery chain of technologies powering the front end often comprises a mix of on-premises assets, cloud services, containers, and APIs.

A degradation or outage to just one of those components can have massive impact. Depending on the architecture of the app and resilience of the backend, an incident in one part can be routed around in the best case scenario, or take down critical systems for hours in the worst case.

Tune in to this episode to learn more about how backend changes led to outages at DBS, Citibank, and a number of Japanese banks—and how other backend issues appeared to contribute to a Google Cloud VMware Engine disruption and potentially also a Microsoft Exchange incident.
