  • 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.
