## What it is
Dapr is a portable, CNCF-graduated distributed application runtime that runs as a sidecar and exposes building-block APIs for service invocation, pub/sub, state management, actors, workflow orchestration, jobs, and agentic AI. It decouples application code from underlying infrastructure so microservices and durable AI agents run portably across cloud and edge environments.

## Use cases
- build resilient microservices with built-in service discovery and retries
- orchestrate durable long-running workflows that survive crashes
- add pub/sub messaging between services without vendor lock-in
- manage state across clouds with pluggable state stores
- build durable AI agents that recover from failures
- schedule jobs and automate business processes in code
- run event-driven applications on Kubernetes and edge
- implement the virtual actor pattern for stateful services

## When to choose
- you're building microservices on Kubernetes and want infrastructure-agnostic APIs
- you need durable workflow execution with tamper-evident history
- you want to swap message brokers or state stores without changing app code
- you're building AI agents that must survive failures and resume progress
- you want built-in security, tracing, and resiliency without boilerplate

## When to avoid
- you have a simple monolith or single-service app with no distributed needs
- you can't run a sidecar (e.g., some serverless or managed platforms)
- your team can't take on an additional runtime dependency and learning curve
- you need direct, fine-grained control over broker or database features
