From Zero to Hero: Event-Driven Architecture
Learn everything you need to start using Event-Driven Architecture
About This Course
Event-driven architecture is considered to be the holy grail of system design in many ways. Its
design is based on events, which are actions around which we can build reactive systems. This leads
to asynchronous, decoupled, persistent, fault-tolerant and scalable systems. In this course, Datadog
Developer Advocate (ex AWS) James Eastham will assume no prior knowledge of EDA and teach you the
fundamentals as well as advanced concepts on understanding, implementing and testing Event-Driven Architecture systems.
