[Architecture Summit Conf] Deep Dive into Cloud Native Dapr Building block

Dapr is an open-source, portable, event-driven runtime that helps developers build resilient, microservice-based applications. It abstracts common distributed system challenges—such as service discovery, state management, pub/sub messaging, and secure secrets access—through a set of language-agnostic building blocks.

Dapr runs as a sidecar process alongside your application, allowing seamless integration without modifying your business logic.

Key Dapr Building Blocks

1. Service Invocation

   • Enables secure, service-to-service communication using HTTP or gRPC.

   • Handles service discovery and load balancing.

2. Publish & Subscribe (Pub/Sub)

   • Facilitates event-driven architecture with support for multiple brokers (Kafka, Redis, Azure Service Bus).

   • Decouples services by letting them publish/subscribe to topics.

3. Actors

   • Implements the virtual actor model, useful for managing stateful objects.

   • Manages concurrency and lifecycle for distributed actors.

4. Observability

   • Integrates with telemetry tools to provide logs, metrics, and tracing out-of-the-box.

   • Compatible with OpenTelemetry.
