Red Hat Senior Architects Marius Bogoevici and Christian Posta recently presented an overview of event-driven architecture, taking the audience from the basics of enterprise integration to microservices and serverless computing. Standing in front of a packed room at Red Hat Summit, their talk addressed four basic points:
- Event-driven architectures have been around for a while. What are they, why are they powerful, and why are back en vogue?
- Messaging is often used as a backbone for event-based distributed systems. What options do we have for cloud-native event-driven architectures?
- Integration is necessary for any organization. How do streaming, cloud-native architectures, and microservices fit in?
- Are Functions-as-a-Service (FaaS) the next utopian architecture? Where do functions fit in a world of microservices?
The entire session was done with three enterprise concerns in mind. First is the divide between agile systems and purpose-built systems. While the purpose-built system is optimized for a small set of use cases, it is very difficult to change if new use cases arise or the old use cases become irrelevant. We have to be agile to adapt to a constantly changing environment. Another concern is resource utilization. We want to eliminate waste and get the most out of our systems and resources, although the cloud in general and containers in particular make more distributed architectures practical. Finally, Christian made the observation that we cannot build complex systems from complex parts. The components we develop must be as simple and understandable as possible.
