Review the definitions for terms used across Cloudflare's Workflows documentation.
| Term | Definition |
| Durable Execution | "Durable Execution" is a programming model that allows applications to execute reliably, automatically persist state, retry, and be resistant to errors caused by API, network or even machine/infrastructure failures. Cloudflare Workflows provide a way to build and deploy applications that align with this model. |
| Event | The event that triggered the Workflow instance. A |
| instance | A specific instance (running, paused, errored) of a Workflow. A Workflow can have a potentially infinite number of instances. |
| step | A step is self-contained, individually retriable component of a Workflow. Steps may emit (optional) state that allows a Workflow to persist and continue from that step, even if a Workflow fails due to a network or infrastructure issue. A Workflow can have one or more steps up to the step limit. |
| Workflow | The named Workflow definition, associated with a single Workers script. |
