Event-Driven Architectures and AWS EventBridge
Explore the fundamentals of event-driven architectures and how AWS EventBridge enables seamless application integration through event buses and pipes. Learn to design decoupled systems using events, define event rules and filters, and optimize event routing. This lesson helps you understand how to connect services efficiently for resilient and scalable cloud applications.
We'll cover the following...
In an event-driven architecture, the decoupled services interact with each other through events. An event can be any substantial change or important business event, such as a transaction, adding reviews, or sensory information. This software design pattern is commonly used in architectures made out of microservices.
A typical event-driven architecture has three important components, which are as follows:
Event producer: The component or system responsible for generating and publishing events. It can be any microservice or third-party software application that emits events. Also, CloudTrail events can be used as a producer.
Event router: This component routes the events from producer to consumer. An example of the event router is an event bus that maps the producer’s events to consumers.
Event consumer: This is the component or ...
