Event-Driven Architecture (EDA) has quickly become a topic that is on the tip of the tongue of many technology professionals. With the popularization of architectural styles, such as microservices, EDA has emerged as a necessary pattern for loose coupling and increased scalability. Implementing EDA through a large, costly, big-bang approach is not the only way. EDA can be implemented through an iterative approach leveraged to drive implementation, while providing the flexibility to evolve over the life of the program. This presentation will offer a unique take on the experience of implementing changes through an EDA approach—directly from the perspective of someone in the trenches. It will identify how this approach is critical to the success of the overall solution for the multi-year program’s goal to create a new claims management system. This presentation will focus on two specific areas: how to capture events from a legacy system, and how to leverage those events as a pattern of integration for building modern business processes. It will provide an overview of the journey through transforming an aging, database-centric application to an event-based system with the ability to respond to changing business demand. It will also discuss EDA patterns such as publish/subscribe, event notification, and event-carried state transfer, which are key building blocks in defining a new ecosystem.
