What are the benefits of event-driven architecture patterns?

See how event-driven architecture patterns can set up an enterprise application for adaptability in a way that monolithic architectures can't.

Event-driven architecture patterns can appear much more complex than application designs that use the Remote Procedure Call protocol and commands between client and server. There are more moving parts with event-driven architectures, but the payoff is in flexibility.

Unlike a call or command that is synchronous between client and server, an event is asynchronous. The application records a change in state as a new record. In a system, there are numerous creators and consumers of event data. This data is immutable and is the backbone of real-time operations and analysis efforts. Asynchronous operation is a key benefit of event-driven architecture adoption.

What are the benefits?

Enterprises can see benefits from event-driven architecture in many application types and scenarios. With distributed microservices, event-driven architecture patterns make up the fabric that enables different services to communicate with each other.

Its distributed design provides better separation of application components than client-server systems. As such, development teams looking for increased agility can evolve faster when they transition applications to an event-driven architecture.

Implementing event-driven patterns

Event-driven architecture patterns may manifest as one-time events in a stateful application, or as streaming events processed through a service like the serverless AWS Lambda or the distributed streaming platform Apache Kafka. 

As IoT systems become widely adopted in the enterprise and the world at large, the stage is set for event-driven architecture to become the norm. IoT sensors record event data, and that data can trigger even more events. Events have the potential to become the economy that powers enterprise application architecture. To make applications well-suited to this reality, enterprise IT organizations should start transitioning to event-driven architecture patterns today.
