Dapr is a portable, open‑source runtime that abstracts common building blocks for distributed applications. It runs as a sidecar alongside each service, providing APIs for service invocation, pub/sub, state management, workflows, actors, and more.

Use cases

• Build microservices that need reliable service‑to‑service calls with built‑in retries and mTLS
• Implement event‑driven architectures using pub/sub without vendor lock‑in
• Create stateful applications with durable key/value storage across clouds
• Orchestrate long‑running business processes with Dapr Workflow
• Develop AI agents that require resilient, checkpointed execution

When to choose

• You need a language‑agnostic runtime that works on any cloud or edge environment
• Your architecture relies on multiple building blocks (service invocation, pub/sub, state) and you want them unified under one API
• You want built‑in observability, tracing, and security for microservice communication
• You prefer a sidecar model that adds capabilities without modifying existing code

When to avoid

• Your project is a simple monolith where the added sidecar overhead is unnecessary
• You require fine‑grained control over networking that conflicts with Dapr’s sidecar proxy
• You need a highly specialized messaging system not supported by Dapr’s pub/sub components
