Concepts
Welcome to the Dapr concepts guide!
Dapr is built around durable execution: the guarantee that your code runs to completion despite crashes, restarts, and outages. At its core is a durable, verifiable workflow engine that orchestrates long-running business processes and powers durable AI agents, backed by a set of modular building blocks and pluggable components that solve the common challenges of building distributed systems.
This section explains the core ideas behind Dapr, from durable workflows, building blocks, and components to its security model, resiliency, and observability.
