Event-Driven Microservices from the Trenches

Microservices are all the rage these days, with almost everyone aspiring to adopt this style of architecture. At Barclaycard, we have embarked on a journey to move from a traditional 3-tier system to a more modern set of isolated, reactive services. This talk recounts experiences developing an array of loosely coupled services that employ techniques such as domain-driven design, EDA, CQRS, and event sourcing, among others.
