ABSTRACT
Events are everywhere—an event can be anything from a new account created, an item placed
in a shopping cart, a financial document submitted, or a healthcare dataset uploaded. Events
are the center of an application in an event-driven architecture, powering communication
between integrated systems and development teams.
This guide introduces key concepts and patterns for event-driven architectures and identifies
the Amazon Web Services (AWS) solutions and services commonly used to implement them.
Additionally, it provides best practices for building event-driven architectures, from designing
event schemas to handling idempotency.
