The combination of cloud, serverless and microservices has taken the service implementation to a different level. Though this has accelerated the monolith to microservices transformation, it has also introduced new complexities around service-to-service communication. With every new service added to the system, the order of communications complexity also increases.

Though AWS services such as SNS, SQS and others helped to some extend, they however failed to offer a flexible way to enable filtered routing of messages between microservices. This is where Amazon’s EventBridge makes its mark in alleviating many of these concerns.

AWS EventBridge promotes a hub-and-spoke communication model between microservices. With its flexible and powerful message filtering capability, services can have a renewed way of performing event-driven communication between them. This talk will start by explaining EventBridge and then, with the help of real use-case scenarios, explain how to enable message routing and filtering while working with the event bus.
