event-driven-architect

Event-driven architectures use asynchronous messaging between microservices to decouple systems. Define clear topic naming conventions, implement idempotent consumers, and use patterns like transactional outbox to ensure reliable inter-service communication across Kafka brokers or Dapr pub/sub abstractions.

Dapr pub/sub abstracts the underlying message broker—Kafka, RabbitMQ, or cloud services—enabling cloud-portable event-driven designs without vendor lock-in. It simplifies resilience patterns, dead-letter handling, and cross-service communication workflows in containerized deployments.

Docker is required for local development and containerized deployment of event-driven services. Kubernetes is optional but recommended for production orchestration of distributed microservices; Dapr works in both Docker Compose and Kubernetes environments to manage pub/sub routing and fault tolerance.

Implement resilience techniques: idempotent message consumers prevent duplicate processing, dead-letter queues capture undeliverable events, and transactional outbox patterns ensure events are published alongside data changes. Dapr abstracts broker-specific retry and timeout logic across services.

Yes. Event-driven patterns support both use cases: emit domain events (like todos.task.created), route them through Dapr pub/sub, and subscribe independent services for notifications or analytics aggregation. Choreography patterns coordinate workflows across multiple subscribers without central orchestration.

Use clear, hierarchical event naming—for example, service.entity.action (todos.task.created)—paired with defined schemas. This prevents naming collisions, enables subscribers to filter topics predictably, and makes event governance auditable across microservices.
